In 2024, scientists demonstrated quantum teleportation through a laboratory optical cable carrying high-speed internet traffic. ・A new study sent entangled photons through a busy fiber-optic cable ...

A small yet innovative experiment is taking place at CERN. Its goal is to test how the CERN-born optical timing signal—normally used in the Laboratory's accelerators to synchronize devices with ...

A research team led by Prof. Lin Yiheng from the University of Science and Technology of China (USTC), collaborating with Prof. Yuan Haidong from the Chinese University of Hong Kong, succeeded in ...

Ronald Hanson is at QuTech and the Kavli Institute of Nanoscience, Delft University of Technology, Delft 2628 CJ, the Netherlands. The authors show that for a 10-km fibre link, entanglement between ...

Just over 200 years after French engineer and physicist Sadi Carnot formulated the second law of thermodynamics, an international team of researchers has unveiled an analogous law for the quantum ...

Nearly a century ago, the physicist Erwin Schrödinger called attention to a quirk of the quantum world that has fascinated and vexed researchers ever since. When quantum particles such as atoms ...

A centimeter-sized crystal has revealed clear signs of quantum entanglement, showing that large, everyday objects can display surprisingly deep quantum behavior. The discovery could help solve the ...

Quantum entanglement — once dismissed by Albert Einstein as “spooky action at a distance” — has long captured the public imagination and puzzled even seasoned scientists. But for today’s quantum ...

Entanglement is a defining feature of quantum physics, but not all entangled states are equal. What techniques can be used to generate maximally entangled states? Artistic impression of quantum ...
