Characterizing and controlling high-order correlation of quantum systems is key for developing quantum devices and switching technologies. Although conventional static and ultrafast spectroscopy gives ...

In recent years, entangled photons—a popular quantum light source—have been widely used in quantum imaging, optical interferometry, quantum computing, quantum communication, and other fields.

The motion of atoms is at the heart of any chemical or structural transformation in molecules and materials. Upon activation of this motion by an external source, several (usually many) vibrational ...

In a breakthrough for antimatter research, the BASE collaboration at CERN has kept an antiproton—the antimatter counterpart of a proton—oscillating smoothly between two different quantum states for ...

An Osaka Metropolitan University-led research team investigated the decay time of coherent longitudinal optical (LO) phonons both in a GaAs 1−x N x epilayer and in a GaAs single crystal, to clarify ...

Bachana Lomsadze is an associate professor of physics at Santa Clara University and a recipient of the National Science Foundation’s CAREER Award and SCU’s Professor Joseph Bayma, S.J. Scholarship ...

The demonstration of the first antimatter quantum bit paves the way for substantially improved tests of nature’s fundamental symmetries. Particles such as the antiproton, which has the same mass but ...

Ultrafast laser spectroscopy allows the ascertainment of dynamics over extremely short time scales, making it a very useful tool in many scientific and industrial applications. A major disadvantage is ...
