In a recent study, researchers at the University of Colorado have resolved phonon Fock states in the spectrum of a superconducting qubit coupled to a multimode acoustic cavity. Fock states (or number states) are quantum states ...
(PhysOrg.com) -- Researchers at MIT and elsewhere have succeeded in creating a synthetic crystal that can very effectively control the transmission of heat -- stopping it in its tracks and reflecting it back. This advance ...

(Phys.org)—A team of researchers with members from institutions in the U.S. and Austria has succeeded in building a device that shows a clear step towards the development of an optical single-phonon detector. In their paper ...
There has been a lot of progress and development in the superconductivity (zero electrical resistance) front owing to its wide range of applications in MRI machines, particle accelerators, and low-loss power cables. However, ...
