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 [...]

Quantum systems may hide memory in unexpected ways. An international team of scientists has taken a closer look at how memory functions in quantum systems and their time evolution. Their study reveals that whether a quantum process appears to have memory depends on how it is examined. From one angle, the process may seem completely [...]

A laser-written glass chip shows how fragile quantum signals can be decoded with high stability and low loss, offering a new path toward practical quantum communication systems. As progress in quantum computing accelerates, many of the encryption methods used today could eventually be rendered ineffective. Quantum cryptography offers a fundamentally different approach to security by [...]
