For years, researchers have tried various ways to coax quantum bits—or qubits, the basic building blocks of quantum computers—to remain in their quantum state for ever-longer times, a key step in ...

Optical coherence extends beyond lasers, with partially coherent light enhancing imaging, communication, and photonic ...

In a novel experiment, physicists have observed long range quantum coherence effects due to Aharonov-Bohm interference in a topological insulator-based device. This finding opens up a new realm of ...

Scientists from DTU have shown that a Fano laser, a new type of microscopic laser, has fundamental advantages compared to other types of lasers. The discovery can be important for many future ...

Scientists work to sync up quantum objects for high-resolution sensing and complex computation. (Nanowerk News) We say a message is incoherent when we can’t make it out, or when it doesn’t make sense.

New research shows that the unique properties of atomic Bose-Einstein condensates extend to the internal spin states of the atoms from which the condensates are formed. Bose-Einstein condensates are ...
