internetQuantum Entangled Computer Memory Over 30 Miles Enables Quantum Internet

Chinese scientists have transmitted quantum computer memory between two entangled clouds of atoms over 50 kilometers. They developed an efficient atom-photon entanglement source that is suitable for low-loss transmission in fibers. This means a quantum internet could span a large …

physicsChip-to-chip Quantum Teleportation and Multi-photon Entanglement in silicon

Silicon is a compelling platform for classical optical telecommunications as well as quantum communications, both through optical fibers. In general, the silicon-based integrated quantum transceivers could provide possible low-cost and high-performance secure communication networks. A reliable transfer of single photon …

physicsQuantum Simulations That Are Ten Thousand Times Faster

Researchers at the University of Warwick and University of Oxford have developed a new way to simulate quantum systems of many particles, that allows for the investigation of the dynamic properties of quantum systems fully coupled to slowly moving ions. …

futureIronbridge Quantum Communication

Cambridge Quantum Computing uses photonics and quantum entanglement to generate truly random numbers. They also constantly verify that quantum randomness is being maintained. Failure to of quantum randomness tests indicates that there has been interference and tampering. Brian Wang Brian Wang …

chinaRussian Quantum Hacking Lab

There is a Quantum hacking lab which is a site of the Russian Quantum Center. This site has a collection of videos, research papers and presentations about quantum cryptography and quantum security. Vadim Makarov worked at the University of Waterloo …

diamondsQuantum Control in Nanodiamonds

Quantum coherence control usually requires low temperature environments. Even for nitrogen-vacancy center spins in diamond, a remarkable exception, the coherence signal is limited to about 700 K due to the quench of the spin-dependent fluorescence at a higher temperature. Here …

militaryGlobal Quantum Communication Network has Been Proven Feasible With 20,000 km Transmissions

The first exchange of a few photons per pulse has been performed between two different satellites 20,000 kilometers apart. This was between the Russian GLONASS constellation and the Space Geodesy Centre of the Italian Space Agency. The longest channel length …

militarySuper-precise Quantum navigation using lasers and super cold atoms

The UK’s first quantum accelerometer for navigation has been demonstrated by a team from Imperial College London and M Squared. Losing GPS (global positioning satellites) service for one day would cost the UK £1 billion. Losing GPS is also a …

futureTen year $1.275 billion US National Quantum Initiative proposed to get more quantum engineers

There is a proposed $1.275 billion National Quantum Initiative to accelerating research and training in quantum computing. The funding would be provided over ten years. Several centers of excellence for quantum computing would help train many quantum engineers. Chris Monroe, …
