Light is usually described using quantum mechanics when phenomena like entanglement enter the picture. But a new paper shows ...
Physicists have long relied on elegant theorems to connect the abstract math of quantum theory with the tangible behavior of ...
A team of researchers at the University of Waterloo have made a breakthrough in quantum computing that elegantly bypasses the ...
Quantum information theory is a field of study that examines how quantum technologies store and process information. Over the ...
Fifty years ago, John Bell made metaphysics testable, but quantum scientists still dispute the implications. Howard Wiseman proposes a way forward. In 1964, Northern Irish physicist John Bell proved ...
The Lieb-Schultz-Mattis (LSM) theorem is an important result in condensed matter physics. The LSM theorem states that a spin chain with half-integer spin and translation and rotation symmetry can not ...
