(Phys.org)—It was an interesting week for physics as a combined team of researchers from China and Singapore demonstrated new violations of local realism—they have shown that all mixed entangled states that conform to ...
(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 ...
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 ...
