Some quantum cryptographers want to find ways to keep messages secret even if the rules of quantum mechanics don’t hold. The ...

Quantum mechanics is extremely successful at describing the behavior of matter at the atomic level. This success forces one ...

A key question in physics is whether gravity follows quantum rules, but testing this is difficult because gravitational ...

In quantum physics, objects can exist in multiple states at the same time—a phenomenon known as quantum superposition, where ...

A number of experiments have been proposed to generate and witness gravitational entanglement, but Aziz and Howl’s work suggests that the presence of gravitational entanglement is not a ‘smoking gun’ ...

Mehdi Namazi wants to sell you quantum entanglement. He and his colleagues at Qunnect have spent nearly a decade building devices that make sharing quantum-entangled particles of light, or photons, ...

A new quantum battery prototype demonstrates fast, scalable charging using quantum effects, bringing the technology closer to ...
