Nitrogen Vacancy Center Diamond Defect Plays a Big Role in Design of Universal Quantum Computer

In the race to design the world's first universal quantum computer, a special kind of diamond defect called a nitrogen vacancy (NV) center is playing a big role. NV centers consist of a nitrogen atom and a vacant site that together replace two adjacent carbon atoms in diamond crystal.

Novel Method to Control Atoms for Future Quantum Computer Networks

In order to develop future quantum computer networks, it is necessary to hold a known number of atoms and read them without them disappearing. To do this, researchers from the Niels Bohr Institute have developed a method with a trap that captures the atoms along an ultra thin glass fiber, where the atoms can be controlled. The results are published in the scientific journal, Physical Review Letters.

Breakthrough Discovery Could Prompt Ideas for New Applications of Wave-Particle Duality

Here's a nice surprise: quantum physics is less complicated than we thought. An international team of researchers has proved that two peculiar features of the quantum world previously considered distinct are different manifestations of the same thing. The result is published 19 December in Nature Communications.

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.

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.

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.

Heriot-Watt University to Play Major Role in Quantum Technology Hubs Network

Heriot-Watt University will play a leading role in a new national network of Quantum Technology Hubs that has received almost £30m funding.

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.

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.
