A team in China has demonstrated the simultaneous teleportation of multiple sideband qumodes in a continuous-variable system, overcoming a longstanding technical barrier.

Researchers at the University of Tuebingen, working with an international team, have developed an artificial intelligence that designs entirely new, sometimes unusual, experiments in quantum physics ...

New evidence suggests a rare triplet superconductor may help quantum computers stay in sync by preserving electron spin ...

A new ultra-fast monitoring system reveals that quantum computer qubits can change from stable to unstable in mere milliseconds.

A pair of photons enters an optical maze, and sometimes they leave as something new. Not new in the everyday sense, since both were still photons when they came out.

While the basic form of QKD enables information to be transmitted securely, it does have some weak points. One of them is ...

A series of quantum physics experiments and theoretical papers now suggest that heat can flow spontaneously from a cold ...

Quantum experiments keep stripping away our everyday intuitions, replacing them with a picture of reality in which cause, effect and even “facts” depend on how we look. New tests of entanglement, ...
