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.

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.

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.
