• Heat Dissipation at the Atomic Level Studied Through Nanotechnology

  
  — Authority:
  Researchers at the University of Michigan are studying the effects of heat at the nanoscale; between atoms. This study will help in understanding how heat behaves in nanoscale systems. Moores Law states that the number of transistors on integrated circuits doubles approximately every two years. This equates to ...

• Closing the last Bell-test loophole for photons

  
  — Authority:
  An international team of researchers has reached a milestone in experimental confirmation of a key tenet of quantum mechanics, using ultra-sensitive photon detectors devised by PML scientists. The work, reported last month in Nature, eliminates the last remaining potential obstacle to a quantum-mechanical ...

• Physicists show self-correcting quantum computers are theoretically possible

  
  — Authority:
  Using exotic components such as color codes, new phases of quantum matter, and extra dimensions, a team of physicists has shown that it’s theoretically possible to construct a quantum computer that has the ability to correct itself whenever an error occurs. “The greatest significance of our work is showing that ...

• Optical quantum Hall effect in graphene

  
  — Authority:
  Graphene is a monolayer sheet of carbon atoms bound in the form of a honeycomb lattice, for experiments on which a Nobel prize was awarded in 2010. Curiously, an electron in graphene behaves like a relativistic (Dirac) particle with zero mass (hence it has been dubbed a neutrino in a solid), and at about 1/300 times ...

  — Authority:
  ‘Quantum ATM’ aims to make us all rich The green uranium-glass core of the ATM If you’ve spent much time looking into the peculiar world of quantum physics and the notion of a so-called quantum superposition that theoretically allows a particle to be everywhere at once, you’ve surely thought of some ways that ...

• Quantum teleportation between atomic systems over long distances

  
  — Authority:
  Researchers have been able to teleport information from light to light at a quantum level for several years. In 2006, researchers at the Niels Bohr Institute succeeded in teleporting between light and gas atoms. Now the research group has succeeded in teleporting information between two clouds of gas atoms and to ...

• Spooky action put to order

  
  — Authority:
  A property known as «entanglement» is a fundamental characteristic of quantum mechanics. Physicists and mathematicians at ETH Zurich show now how different forms of this phenomenon can be efficiently and systematically classified into categories. The method should help to fully exploit the potential of novel quantum ...

• First Observation of Spin Hall Effect in a Quantum Gas Is Step Toward ‘Atomtronics’

  
  — Authority:
  Researchers at the National Institute of Standards and Technology (NIST) have reported* the first observation of the “spin Hall effect” in a Bose-Einstein condensate (BEC), a cloud of ultracold atoms acting as a single quantum object. As one consequence, they made the atoms, which spin like a child’s top, skew ...

• May the force be with us? Precise measurements test quantum electrodynamics, constrain possible fifth fundamental force

  
  — Authority:
  Quantum electrodynamics (QED) – the relativistic quantum field theory of electrodynamics – describes how light and matter interact – achieves full agreement between quantum mechanics and special relativity. (QED can also be described as a perturbation theory of the electromagnetic quantum vacuum.) QED solves the ...

• Most experiments that claim to show the quantum Zeno paradox fall short, study says

  
  — Authority:
  By their very nature, unstable particles will eventually decay, some faster than others. But according to the quantum Zeno paradox (QZP), an unstable particle that is observed continuously has been said to never decay. Though counterintuitive, this effect has been claimed to show up experimentally in numerous ways. ...
