Coherence in quantum dynamics is at the heart of fascinating phenomena beyond the realm of classical physics, such as quantum interference effects, entanglement production and geometric phases.

Researchers from the National University of Singapore (NUS) have successfully simulated higher-order topological (HOT) lattices with unprecedented accuracy using digital quantum computers. These ...

Topology, which is a branch of mathematics, is rising as a universal notion in physics, from condensed matter physics to classical wave systems. Topology has been received particularly warmly in ...

A new state of matter, called quantum spin liquid, produces long-range quantum entanglement which might help make quantum computers. They could enable topological qubits. Bill Gates and Microsoft have ...
