Future Quantum Computers Could be Connected to a 'Quantum Internet'

Future Quantum Computers Could be Connected to a 'Quantum Internet'

In the same way as we now connect computers in networks through optical signals, it could also be possible to connect future quantum computers in a 'quantum internet'. The optical signals would then consist of individual light particles or photons. One prerequisite for a working quantum internet is control of the shape of these photons. [More]
Compact, High-Value Resistors for Nanoscale Quantum Circuits

Compact, High-Value Resistors for Nanoscale Quantum Circuits

Researchers from the London Centre for Nanotechnology have made new compact, high-value resistors for nanoscale quantum circuits. The resistors could speed the development of quantum devices for computing and fundamental physics research. The researchers describe the thin-film resistors in an article in the Journal of Applied Physics, from AIP Publishing. [More]

Controlled Emission and Splitting into Separate Electron Pairs from Semiconductor Quantum Dot

In quantum optics, generating entangled and spatially separated photon pairs (e.g. for quantum cryptography) is already a reality. So far, it has, however, not been possible to demonstrate an analogous generation and spatial separation of entangled electron pairs in solids. [More]

Diamond and Graphene for Quantum Computers

Nitrogen-vacancy centers in diamonds could be used to construct vital components for quantum computers. But hitherto it has been impossible to read optically written information from such systems electronically. [More]
Researchers Demonstrate More Robust Technique for Approximate Quantum Dynamics

Researchers Demonstrate More Robust Technique for Approximate Quantum Dynamics

The most widely used approximate techniques to simulate quantum dynamical effecst for atomic nuclei (CMD and RPMD) exhibit major artefacts when simulating vibrational spectra of molecular compounds, particularly at low temperature. Recent methodological advances make it possible to fix these problems, extending the range of applicability of these simulations. [More]

Oxford-Led NQIT Hub to Develop Technologies for Fully-Functional Quantum Computer

A consortium of academic and industrial partners led by Oxford University will deliver quantum technologies including building a fully-functional prototype quantum computer. [More]
Atomic Memory with Outstanding Parameters for Quantum Information Technologies

Atomic Memory with Outstanding Parameters for Quantum Information Technologies

Neither quantum computers nor quantum cryptography will become prevalent technologies without memory systems able to manipulate quantum information easily and effectively. The Faculty of Physics at the University of Warsaw has recently made inroads into popularizing quantum information technologies by creating an atomic memory with outstanding parameters and an extremely simple construction.
