The extraction of work (i.e., usable energy) from quantum processes is a key focus of quantum thermodynamics research, which explores the application of thermodynamics laws to quantum systems.

A series of quantum physics experiments and theoretical papers now suggest that heat can flow spontaneously from a cold object to a hot one, provided the right quantum conditions are in place. This ...

Understanding the boundary between classical and quantum physics has long been a central question in science. While thermal light fields have traditionally been viewed as classical, the team ...

Scientists have developed a new way to build rare-earth crystals that boosts quantum coherence to tens of milliseconds. This leap could extend quantum communication distances from city blocks to ...
