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, …

artifiicial intelligenceBecoming an exponential winner – SU Summit 2018

Amin Toufani is an economist who discussed that there will be exponential winners and losers. He discusses what it takes for individuals and companies to be future winners. Amin gave parts of the SU Summit 2018 at two other events. …

air forceFaster weapons development and rollout critical with rise of hypersonics and anti-stealth technology

The US Air Force is finishing engineering details on an aggressive plan to prototype, test and deploy hypersonic weapons on a faster schedule. Having a faster development and rollout of offensive military capabilities is critical with decline of stealth and …

lasersPhotonic precision measurement chip shows mass production of quantum sensors is possible

Researchers at the National Institute of Standards and Technology (NIST) have created a chip on which laser light interacts with a tiny cloud of atoms to serve as a miniature toolkit for measuring important quantities such as length with quantum …

laserAnalog quantum simulation based on laser-trapped circular Rydberg atoms

State-of-the-art techniques make it possible to build a spin-chain quantum simulator based on laser-trapped circular Rydberg atoms. This simulator combines the flexibility of atomic lattices and the individual atomic observable read-out typical of ion trap, together with the strong dipole-dipole …

darpaDARPA aims for 100-fold performance improvement for defense-related sensors and devices

The performance and reliability of quantum sensors and devices is dependent on the length of time the underlying quantum states can remain coherent. If you wait long enough, interactions with the environment will make the state behave like a conventional …

materialsNIST creates spectrometer with 10,000 times more precision than standard devices

A new NIST (National Institute of Standards and Technology) spectrometer measures single photons with great precision. The device could help bring about “quantum communications” networks, which would use individual particles of light to send bits of information. Because each bit …
