In a quantum system of arrayed two-level atoms interacting with light, the interacted (dressed) photon is propagating in a periodic medium and its eigenstate ought to be of Bloch type with lattice ...

A layered magnetic semiconductor called CrSBr converted microwave-driven magnetic excitations into coherent optical signals ...

Just as a leaf drifts along with a stream, objects in other moving fluids normally drift along with the flow. That is, unless ...

Physicists have confirmed the two foundational postulates of Richard Feynman’s path-integral approach to quantum mechanics in ...

Quantum technologies have long been limited by an awkward mismatch: the wavelengths where quantum light sources work best are ...

Radiofrequency pulses kept a crystal quantum memory coherent long enough to preserve individual photons across ...

Scientists have, for the first time, experimentally proven that angular momentum is conserved even when a single photon splits into two, pushing quantum physics to its most fundamental limits. Using ...

Cold atom experiments are among the most powerful and precise ways of investigating and measuring the universe and exploring the quantum world. By trapping atoms and exploiting their quantum ...

For nearly half a century, resonance fluorescence has served as one of the cleanest and most fundamental laboratories in all of quantum optics. Shine a laser on a single two-level atom, tuned ...

Physicists have developed a spectral-filtering technique that strips away unwanted extra photons from quantum light sources, tackling one of the most persistent obstacles in quantum optics. The method ...

This opens the door to a new way of doing science, one in which humans are not the sole architects of experimentation. Artificial intelligence has begun to tackle a task once thought to be uniquely ...
