Quantum entanglement has shifted from a philosophical puzzle to a design brief for engineers working at the scale of atoms, photons and phonons. As researchers learn to control this fragile ...

Space rarely gives up its secrets easily. For instance, what looks like a single ...

Many quantum researchers are working toward building technologies that allow for the existence of a global quantum internet, in which any two users on Earth would be able to conduct large-scale ...

Adiabatic quantum computing An example problem represented by an energy landscape. Each point on the landscape represents a candidate solution. The deepest valley represents the actual solution with ...

Fig.1 Schematic of the experimental setup for continuous-variable entanglement-assisted quantum comumication. Alice encodes classical signals on the ancilla beam by an amplitude modulator (AM) and a ...
