Absolute zero in the quantum computer: Formulation for the third law of thermodynamics
When many quantum particles interact, complex systems can be formed. And this complexity allows reaching a temperature of absolute zero—at least in principle.

Exceptional points are a distinct type of spectral singularity in non-Hermitian systems and their intriguing physics are in study with optical exceptional points. Exceptional points are singularities in the energy functions ...
Scientists have, for the first time, developed a quantum experiment that allows them to study the dynamics, or behavior, of a special kind of theoretical wormhole. The experiment has not created an actual wormhole (a rupture ...
