Nuclear Quantum Entangled States Sensors – NuQuESTS

Identifying and characterizing new physical systems suitable as improved quantum resources is at the heart of the next generation of quantum research and technology. For example, spin based implementations controlled by light allow for applications in optical quantum communication, hybrid optomechanical spin probing for quantum metrology, precision spectroscopy, new time and frequency standards as well as laboratory searches of new physics and hold promise for future quantum memories. Creating, controlling and using quantum resources on relevant timescales necessitates the use of matter, which requires a fine degree of control and, more importantly, exquisite isolation. As quantum information is quite fragile, typical systems are limited to short timescales and need to be cooled to very low temperatures or isolated to high degrees. Here we propose storing and manipulating quantum resources via the nuclear spin of noble gas atoms, which due to the closed electronic shell offer a splendidly isolated system with hours of coherence time even at room temperature.
