Our work on measureing effective temperature of qubits is published in PRL

In our recent work published in Physical Review Letters, we have proposed a new technique to measure the effective temperature of a qubit by taking advantange of the correlation generated between two sequential measurements. We experimentally demonstrated measurement of spurious qubit population with accuracy of up to 0.01%. This accuracy enabled us to perform “temperature spectroscopy” of the qubit which helps to shed light on sources of the decoherence and better the initializing of qubit to ground state.
