A quantum Szilard engine that can achieve two-level system hyperpolarization

https://phys.org/news/2023-07-quantum-szilard-two-level-hyperpolarization.html

"converts information into energy, 2-level system hyperpolarization of a qubit environment... operates on an individual quantum bit... induces hyperpolarization of qubit environment...  energy relaxation time above 50 ms., can cool to reduce qubit population below 20 mK temperature of cryostat and heated create environment with qubit population 80%... TLSs virtually lossless... orders magnitude longer relaxation times... goal remove all TLSs from environment and improve qubit coherence, quadruple qubit T1"
