Quantum bath suppression in a superconducting circuit by immersion cooling

Quantum bath suppression in a superconducting circuit by immersion cooling

Abstract Quantum circuits interact with the environment via several temperature-dependent degrees of freedom. Multiple experiments to-date have shown that most properties of superconducting devices appear to plateau out at T ≈ 50 mK – far above the refrigerator base temperature. This is for example reflected in the thermal state population …
