quantum entanglement

Researchers report a quantum memory that has stored single photons for a record length of time, a result described as a major step towards building a quantum internet. Long-lived storage of individual light particles is a key requirement for quantum repeaters, the devices needed to send entangled signals across continental distances. The achievement is drawing attention as a milestone in quantum communication research.

Researchers have quantum-entangled a tiny levitating glass nanoparticle with light at room temperature, a milestone in quantum physics. Achieving entanglement without extreme cooling brings the quantum behaviour of larger objects closer to everyday conditions, with potential implications for quantum sensing and computing. The result is drawing attention across the science community.

Researchers publishing in Nature report a deterministic and programmable fusion technique for generating photonic graph states at scale. Photonic graph states are entangled light states central to photonic quantum computing, networking and repeaters. Making fusion deterministic rather than probabilistic, while keeping it programmable, is presented as a step toward scalable quantum photonics. The finding matters because scaling entangled photon sources has been a key bottleneck for optical quantum technologies.
