An international team, including Chinese researchers, has demonstrated a large-scale integrated quantum photonic circuit, which may pave the way for manufacturing massive components for the realization of an optical quantum computer, according to a study recently released by the University of Bristol.
Researchers from Google are testing a quantum computer with 72 quantum bits, or qubits, scientists reported at a meeting of the American Physical Society — a big step up from the company’s previous nine-qubit chip.
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated that quantum physics might enable communications and mapping in locations where GPS and ordinary cellphones and radios don't work reliably or even at all, such as indoors, in urban canyons, underwater and underground.
Scientists claim to have produced the first-ever blueprint for a large-scale quantum computer in a development that could bring about a technological revolution on a par with the invention of computing itself.
In a step that brings silicon-based quantum computers closer to reality, researchers at Princeton University have built a device in which a single electron can pass its quantum information to a particle of light. The particle of light, or photon, can then act as a messenger to carry the information to other electrons, creating connections that form the circuits of a quantum computer.
