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 city network. They entangled two clouds of a billion atoms then extracted a photon from …
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 qubits from one silicon device to another has already been shown, and the distribution of …
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. Effectively, they have made the simulation of the quantum electrons so fast that it could …
Quantum Supremacy Using a Programmable Superconducting Processor
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 WangBrian Wang is a Futurist Thought Leader and a popular Science blogger with 1 million readers per …
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 for many years and recently has been in Shanghai and Moscow. Brian WangBrian Wang is …
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 researchers overcome this limit and demonstrate quantum coherence control of the electron spins of nitrogen-vacancy …
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 previously demonstrated was around 7,000 km, in an experiment using a Medium-Earth-Orbit (MEO) satellite that …
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 large concern for advanced militaries. Precision warfare depends upon GPS. UK team has demonstrated a …
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, cofounder of IonQ, was one of the authors. IonQ is developing a general-purpose trapped ion …
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. Amin has updated and expanded his thesis. There are more powerful business models with more …
