• Graphene joins the race to redefine the ampere

  A new joint innovation by the National Physical Laboratory (NPL) and the University of Cambridge could pave the way for redefining the ampere in terms of fundamental constants of physics. The world's first graphene single-electron pump (SEP), described in a paper in Nature Nanotechnology, provides t more

• UCLA physicists' technique for cooling molecules may be a stepping stone to quantum computing
  

  The next generation of computers promises far greater power and faster processing speeds than today's silicon-based based machines. These "quantum computers" — so called because they would harness the unique quantum mechanical properties of atomic particles — could draw their computing power from a more

• Quantum computers counting on carbon nanotubes
  

  Carbon nanotubes can be used as quantum bits for quantum computers. A study by physicists at the Technische Universitaet Muenchen (TUM) has shown how nanotubes can store information in the form of vibrations. Up to now, researchers have experimented primarily with electrically charged particles. Bec more

• Tunable Surface Electron Spin Splitting with Electric Double-Layer Transistors Based on InN

  Electrically manipulating electron spins based on Rashba spin–orbit coupling (SOC) is a key pathway for applications of spintronics and spin-based quantum computation. Two-dimensional electron systems (2DESs) offer a particularly important SOC platform, where spin polarization can be tuned with an e more

• Quantum Iterative Deepening with an Application to the Halting Problem

  by Luís Tarrataca, Andreas Wichert Classical models of computation traditionally resort to halting schemes in order to enquire about the state of a computation. In such schemes, a computational process is responsible for signaling an end of a calculation by setting a halt bit, which needs more

• Reduced-Dimensional Quantum Computations for the Rotational–Vibrational Dynamics of F––CH4 and F––CH2D2

  Variational rotational–vibrational quantum chemical computations are performed for the F––CH4 and F––CH2D2 anion complexes using several reduced-dimensional models in a curvilinear polyspherical coordinate system and utilizing an accurate ab initio potential energy surface (PES). The implementation more
