Team takes giant step forward in generating optical qubits

An optical chip developed at INRS by Prof. Roberto Morandotti's team overcomes a number of obstacles in the development of quantum computers, which are expected to revolutionize information processing. An international research ...

Researchers take two big steps toward quantum computing

(Phys.org)—"Spooky action at a distance," Einstein's famous, dismissive characterization of quantum entanglement, has long been established as a physical phenomenon, and researchers are keen to develop practical applications ...

Physicists demonstrate new violations of local realism

(Phys.org)—Erwin Schrödinger once famously stated that quantum entanglement is "the characteristic trait of quantum mechanics" that distinguishes it from classical theories. Now in a new paper, physicists have demonstrated ...

An efficient approach to concentrate arbitrary N-particle W state

Entanglement is an important quantum resource in both quantum communication and computation. The applications of entanglement information processing such as quantum teleportation, quantum key distribution (QKD), quantum dense ...
