Future quantum computing will require correlations between distant modules—a feature known as distributed entanglement.

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 centimeter-sized crystal has revealed clear signs of quantum entanglement, showing that large, everyday objects can display ...

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 ...

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 ...

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 ...

Quantum entanglement, a bewildering phenomenon where particles become interconnected regardless of the distance separating them, challenges our fundamental understanding of reality. It has puzzled ...

One of the most surprising predictions of physics is entanglement, a phenomenon where objects can be some distance apart but still linked together. The best-known examples of entanglement involve tiny ...

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 ...

Adiabatic quantum computing An example problem represented by an energy landscape. Each point on the landscape represents a candidate solution. The deepest valley represents the actual solution with ...

SLAC and Stanford scientists uncovered a quantum spin liquid, a state of matter that may have applications for quantum information. The blue-green lab-grown crystals look like solid rocks, but their ...
