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

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 ...

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 ...

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 ...

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 ...

Researchers have demonstrated a new way to make spatially separated lasers synchronize and act as a single coherent light source—without extreme conditions or complex materials.

We say a message is incoherent when we can’t make it out, or when it doesn’t make sense. A scribbled note, a drunken argument or a conversation taking place five tables down in a crowded cafe might ...

Quantum biology is a relatively new field of study in quantum mechanics which can use quantum theory in some aspects of biology that classical physics cannot describe precisely. In the beginning, it ...

The Nobel Prize in Physics in 2005 was awarded half to Roy J. Glauber for his contribution to the quantum theory of optical coherence. The other half went to T. W. Hänsch and John L. Hall for their ...
