A new method reveals hidden order in quantum systems, potentially transforming how they are measured and used. A long-standing challenge in quantum physics may finally have a practical solution. Researchers in Japan have developed a new way to identify complex quantum states in a single step, potentially removing one of the biggest bottlenecks in building [...]

A team of physicists has uncovered a hidden topological structure within one of the most widely used sources of quantum entanglement. Researchers from the University of the Witwatersrand in South Africa, working together with scientists from Huzhou University, have identified an unexpected property in a widely used quantum optics technique. Experiments that routinely generate entangled [...]

A team in China has demonstrated the simultaneous teleportation of multiple sideband qumodes in a continuous-variable system, overcoming a longstanding technical barrier. Quantum teleportation is one of the key tricks behind entanglement-based quantum communication. It does not move matter from place to place. Instead, it transfers the information that defines a quantum state from one [...]
