According to recent research from the United States, "From microwave and resonant tunneling spectroscopy measurements we independently obtained all device parameters needed to reconstruct the Hamiltonian of an rf-SQUID flux qubit."
"Energy relaxation of the qubit as a function of flux bias and temperature was investigated experimentally. It is found that the energy relaxation rate at different flux biases scales to a universal temperature dependence," wrote W. Qui and colleagues, University of Kansas.
The researchers concluded: "This universal T-dependence of T-1 time agrees well with a theoretical model in which the thermal equilibrium population of ...
