Non-perturbative interactions (i.e., interactions too strong to be described by so-called perturbation theory) between light and matter have been the topic of numerous research studies. Yet the role that quantum properties ...
Scientists from the University of Birmingham and the University of Cambridge have developed a new method for detecting mid-infrared (MIR) light at room temperature using quantum systems.

What plagues quantum upscaling? Most quantum computing devices are dependent on using complex physical phenomena that are either very short-lived (~10-12 seconds) and/or only survive at ultra-low temperatures (e.g., 10-3 ...
Quantum teleportation allows quantum information to be transferred to a remote location by using quantum entanglement and classical communication. It has been achieved with varying rates of independent photons of quantum ...
