Kyoto, Japan -- The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to a situation in which it is impossible to describe the physics of each ...

Scientists have finally unlocked a way to identify the elusive W state of quantum entanglement, solving a decades-old problem and opening paths to quantum teleportation and advanced quantum ...

The fragility and laws of quantum physics generally make the characterization of quantum systems time‑consuming. Furthermore, ...

Additionally, they detected phenomena such as nonclassical photon bunching, providing direct evidence of the dark state's formation. Although such states usually suppress photon emission, under ...

Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...
