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 ...

Quantum teleportation has moved from science fiction into laboratory reality, but not in the way popular culture imagines. Instead of beaming people or objects across space, physicists are learning ...

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 ...
