Electrical control of nuclear spin qubits

Using a spin cascade in single-molecule magnet, the  scientists demonstrated how nuclear spins can be manipulated with  electric fields. Electric manipulation allows for a quick and specific  switching of quantum bits. The experimental results are now reported in  the journal <i>Science</i> .         <br />                           <div>             </div>One of the most ambitious goals of nanotechnology is to realize a quantum computer. Such a computer based on <a href="http://phys.org/tags/quantum+mechanics/" rel="tag">quantum mechanics</a> principles is to solve tasks much more efficiently than a classical  computer. While the latter works with bits that assume the value of zero  or one, a quantum computer uses so-called quantum bits, briefly  referred to as qubits, as smallest computation units. They may also  assume values in between. Qubits may rely on nuclear spins, i.e.  intrinsic angular momentums of atomic nuclei. They orient relative to a <a href="http://phys.org/tags/magnetic+field/" rel="tag">magnetic field</a> in upward (up) or downward (down) direction. Interlinkage of qubits  with each other results in mixed quantum states, on the basis of which  many calculation steps can be executed in parallel.<br /> To integrate nuclear spin-based qubits into <a href="http://phys.org/tags/electronic+circuits/" rel="tag">electronic circuits</a> and specifically trigger novel information processes, specific electric  manipulation of nuclear spins is required. A team of scientists of the  KIT and the Centre National de la Recherche Scientifique (CNRS) in  Grenoble and Strasbourg recently succeeded for the first time in  manipulating a single nuclear spin in a purely electric manner. "Use of  electric instead of magnetic fields paves the way to addressing quantum  states in conventional electronic circuits," explains Professor Mario  Ruben, Head of the Molecular Materials Research Group of KIT's Institute  of Nanotechnology (INT). "There, quantum states can be manipulated  specifically by so-called displacement currents. Then, they can be  directly read out electronically."<br /> For their experiments, the researchers used a nuclear spin-qubit  transistor that consists of a single-molecule magnet connected to three  electrodes (source, drain, and gate). The single-molecule magnet is a  TbPc2 molecule – a single metal ion of terbium that is enclosed by  organic phthalocyanine molecules of carbon, nitrogen, and hydrogen  atoms. The gap between the electric field and the spin is bridged by the  so-called hyperfine-Stark effect that transforms the electric field  into a local magnetic field. This quantum mechanics process can be  transferred to all <a href="http://phys.org/tags/nuclear+spin/" rel="tag">nuclear spin</a> systems and, hence, opens up entirely novel perspectives for  integrating quantum effects in nuclear spins into electronic circuits.<br />Reference :<br />http://phys.org/news/2014-06-electrical-nuclear-qubits.html </div>

Proteins 'ring like bells'

<div dir="ltr" style="text-align: left;"><br />          As far back as 1948, Erwin Schrödinger—the inventor of modern  quantum mechanics—published the book "What is life?"<br /><br />In it, he suggested  that quantum mechanics and coherent ringing might be at the basis of  all biochemical reactions. At the time, this idea never found wide  acceptance because it was generally assumed that vibrations in protein  molecules would be too rapidly damped.<br /><br /><div></div>Now, scientists at the University of Glasgow have proven he was on the right track after all.<br />Using modern laser spectroscopy, the scientists have been able to  measure the vibrational spectrum of the enzyme lysozyme, a protein that  fights off bacteria. They discovered that this enzyme rings like a bell  with a frequency of a few terahertz or a million-million hertz. Most  remarkably, the ringing involves the entire protein, meaning the ringing  motion could be responsible for the transfer of energy across proteins.<br />The experiments show that the ringing motion lasts for only a  picosecond or one millionth of a millionth of a second. Biochemical  reactions take place on a picosecond timescale and the scientists  believe that evolution has optimised enzymes to ring for just the right  amount of time. Any shorter, and biochemical reactions  would become inefficient as energy is drained from the system too  quickly. Any longer and the enzyme would simple oscillate forever:  react, unreact, react, unreact, etc. The picosecond ringing time is just  perfect for the most efficient reaction.<br /><br /><br />These tiny motions enable proteins to morph quickly so they can  readily bind with other molecules, a process that is necessary for life  to perform critical biological functions like absorbing oxygen and  repairing cells.<br />The findings have been published in <i>Nature Communications</i>.<br /><br /><br />Klaas Wynne, Chair in Chemical Physics at the University of Glasgow  said: "This research shows us that proteins have mechanical properties  that are highly unexpected and geared towards maximising efficiency.  Future work will show whether these mechanical properties can be used to understand the function of complex living systems."<br /><br />Reference :<br />http://phys.org/news/2014-06-proteins-bells.html </div>

Space-based experiment could test gravity's effects on quantum entanglement

<div dir="ltr" style="text-align: left;"><div style="clear: both; text-align: center;"><a href="http://beva.tk/wp-content/uploads/2014/05/becorbits.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="290" src="http://beva.tk/wp-content/uploads/2014/05/becorbits.jpg" width="320" /></a></div>                    <br />                               (Phys.org) —Physicists are continually looking for ways to unify  the theory of relativity, which describes large-scale phenomena, with  quantum theory, which describes small-scale phenomena. In a new proposed  experiment in this area, two toaster-sized "nanosatellites" carrying  entangled condensates orbit around the Earth, until one of them moves to  a different orbit with a different gravitational field strength. As a  result of the change in gravity, the entanglement between the  condensates is predicted to degrade by up to 20%. Experimentally testing  the proposal may be possible in the near future.         <br />                           <div>             </div>The paper, which is published in a recent issue of the <i>New Journal of Physics</i> by David Edward Bruschi, et al., theoretically demonstrates how relativistic effects impact the quantum world. <br /> "Our work shows that it is possible to test gravitational effects,  which are thought to affect classical systems at large and very large  scales, with genuinely (small) entangled quantum systems," Bruschi told <i>Phys.org</i>. "Our results aid the understanding of the effects of relativity on entanglement, an important resource for quantum information processing. Since we lack a theory that merges quantum theory  and relativity, our work can help direct future theoretical and  experimental efforts that investigate quantum effects at large scales."<br /> Besides being of fundamental interest, understanding how gravity and other relativistic features affect quantum entanglement will help physicists develop quantum technologies  for space-based applications. In a sense, space-based quantum  technologies will take classical space-based technologies such as GPS  into the quantum regime. It's well-known that GPS satellites require  relativistic corrections to accurately determine time and position, and  the same will hold true for quantum technologies.<br /> While GPS is widespread, however, quantum technologies have not yet  been developed for the space environment, although several ideas have  been proposed. While most of these proposals fall under the framework of  the theory of quantum mechanics, the new proposal differs in that is  developed within the framework of quantum field theory. This theory  merges quantum theory and relativity in the sense that matter and  radiation are quantized, while space time is treated as a classical  background. The physicists here argue that quantum field theory provides  a better model for understanding the effects of gravity on quantum  properties. <br />                  <div>                                                                         </div>                          Using a quantum field theory framework, the physicists have  expanded upon previous research that showed that changes in acceleration  affect entanglement. Due to the equivalence principle, this means that  changes in gravity should also affect entanglement. <br /> This is exactly what the physicists found in their analysis. Their  proposed experiment involves two space experimentalists, whom the  scientists call Valentina and Yuri—named after Valentina Tereshkova and  Yuri Gagarin, the first woman and man to go to space. Valentina and Yuri  each prepare a Bose-Einstein condensate (BEC), an ultracold group of  atoms occupying their lowest energy state, which allows quantum effects  to become visible on the macroscopic scale. The BECs' phonon modes are  then entangled with each other.<br />                           Each BEC, which together with its enclosing and maintaining  apparatuses has a volume of 0.5 liters, is then loaded onto its own 20  cm x 20 cm nanosatellite. Currently, researchers are working on the CanX  4 and CanX 5 nanosatellites with these dimensions. The nanosatellites  start out by moving in the same circular orbit but in opposite  directions. Then one of them receives a "velocity kick"—a change in  velocity that moves it to an elliptical orbit. After navigating half of  this new orbit, a second velocity kick puts the satellite into another  circular orbit, different from the first one. Now the two satellites are  in different orbits.<br /> The degradation of entanglement between the BECs is expected to occur  immediately after the orbit-hopping BEC undergoes its first change in  velocity, and can be observed any time that BEC is moving in a different  orbit. Although detecting entanglement between the phonon modes in BECs  has not yet been achieved, it is currently a topic of great interest  and may be possible in the near future. Since CanX 4 and CanX 5 are  designed to determine positions with an accuracy of cm, even a small  change in orbit should lead to an observable effect on the initial  quantum entanglement. <br />                           Although entanglement can suffer a relatively large degradation due  to a change in gravity, there is a bright side to the effect. The  researchers also found that the strength of the entanglement oscillates  periodically with respect to the gravitational difference between the  two orbits. This means that it may be possible to find a situation in  which entanglement  is not degraded by accurately controlling the satellites' positions.  This is one way in which the results will allow researchers to maximize  the potential uses of future space-based quantum technologies.<br /> "I believe that our results can be employed to develop future quantum  communication and positioning technologies, ultraprecise accelerometers  and navigation systems which would benefit from our better  understanding of the interplay between quantum physics and relativity  theory," Bruschi said.<br /> In the future, the researchers plan to further investigate both the  fundamental and practical aspects of quantum and relativistic effects.<br />                          "My goal is to develop space-based relativistic quantum technologies  that will exploit both quantum and relativistic effects to bring the  game to the next level," Bruschi said. "I believe that there is much to  learn about the overlap of quantum mechanics and relativity theory at  large scales and that the applications can be far reaching: from  providing a theoretical basis for future space technologies to deepening  our understanding of the laws of nature."<br /><br />Reference :<br />                 http://phys.org/news/2014-05-space-based-gravity-effects-quantum-entanglement.html </div>

Observation of unexpectedly deformed neutron-rich magnesium nuclei prompts rethink of nuclear shell structure

<div dir="ltr" style="text-align: left;"><div style="clear: both; text-align: center;"><a href="http://beva.tk/wp-content/uploads/2014/01/nuclearislan.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="246" src="http://beva.tk/wp-content/uploads/2014/01/nuclearislan.jpg" width="400" /></a></div>               Although much is known about atoms and their nuclei, scientists continue  to make surprising discoveries as they probe the properties of some of  the more exotic isotopes. Pieter Doornenbal from the RIKEN Nishina  Center for Accelerator-Based Science (RNC) and co‐workers have made  another such discovery with the observation that magnesium nuclei with a  large number of neutrons appear to lose the nuclear shell structure  that has become fundamental to our understanding of the nucleus.<br />         <br />           The protons and neutrons that make up an atomic nucleus are kept together by a balance of nuclear forces. When the number of neutrons is similar to the number of protons, the nucleus is generally stable and the nucleons arrange themselves in shells as a consequence of the laws of quantum mechanics.<br />         <br />          Nuclear physicists now widely accept that nuclei with 2, 8, 20, 28, 50, 82 or 126 neutrons or protons are particularly stable due to the complete filling of these shells. Nuclei with such 'magic numbers' of protons or neutrons are spherical, whereas nuclei with numbers of nucleons that diverge from these magic values are increasingly deformed. <br /><br />          Doornenbal and his colleagues investigated the shape of magnesium nuclei with 22, 24 or 26 neutrons—a significant imbalance of neutrons against magnesium's 12 protons. "Studying such nuclei is now possible thanks to the RNC's Radioactive Isotope Beam Factory, which provides the world's highest-intensity radioactive isotope beams," says Doornenbal. The results indicate that the magic numbers for neutron-rich nuclei—and hence the filling of nuclear shells—might differ from those of the naturally occurring stable nuclei, in which the numbers of protons and neutrons are roughly equal.<br /><br />         The beams of magnesium nuclei were produced by first bombarding a high-energy beam of calcium nuclei against a thin beryllium target. The collision created a multitude of different nuclei that were then screened using magnetic fields to select precursor nuclei—aluminum-37, aluminum-39 and silicon-40. The desired magnesium nuclei were then obtained by bombarding the precursor nuclei against a carbon target to knock out additional nucleons.<br /><br />        The researchers probed the shape of the magnesium nuclei by measuring the high-energy electromagnetic waves that they emit. By comparing these results to theoretical calculations and previous experimental work, the team inferred a large 'island' of deformation in the isotope chart for neutron-rich nuclei with 20 to 28 neutrons. "This behavior is also expected to occur for larger magic numbers," says Doornenbal. "However, we do not yet have the experimental tools to study it in these regions."<br /><a href="http://phys.org/news/2014-01-unexpectedly-deformed-neutron-rich-magnesium-nuclei.html" target="_blank"><br /></a><a href="http://phys.org/news/2014-01-unexpectedly-deformed-neutron-rich-magnesium-nuclei.html" target="_blank"><br /></a><a href="http://phys.org/news/2014-01-unexpectedly-deformed-neutron-rich-magnesium-nuclei.html" target="_blank">Reference:</a><br /><div style="left: -99999px; position: absolute;">The protons and <a href="http://phys.org/tags/neutrons/" rel="tag">neutrons</a> that make up an atomic nucleus are kept together by a balance of  nuclear forces.
