The quantum sensing (not computing!) they're referring to is more likely related to capabilities such as this: Room-Temperature Solid-State Maser Amplifier [...] Here, we report on a continuous-wave solid-state maser amplifier operating at room temperature. We achieve this feat using a practical setup that includes an ensemble of nitrogen-vacancy center spins in a diamond crystal, a strong permanent magnet, and a simple laser diode. We describe important amplifier characteristics including gain, bandwidth, compression power, and noise temperature and discuss the prospects of realizing a room-temperature near-quantum-noise-limited amplifier with this system. Finally, we show that in a different mode of operation the spins can be used to reduce the microwave noise in an external circuit to cryogenic levels, all without the requirement for physical cooling. https://journals.aps.org/prx/abstract/10.1103/PhysRevX.14.041066 https://journals.aps.org/prx/abstract/10.1103/PhysRevX.14.04... https://www.unsw.edu.au/newsroom/news/2024/12/Boosting_weak_microwave_signals_purple_diamonds https://www.unsw.edu.au/newsroom/news/2024/12/Boosting_weak_... The "near-quantum-noise-limited" aspect means that these systems might eliminate thermal noise assosciated with traditional electronic amplifiers & drastically improve the performance of radio receivers & detectors (among other things).
