Microscopic bath effects on noise spectra in semiconductor quantum dot qubits
Microscopic bath effects on noise spectra in semiconductor quantum dot qubits
When a system is thermally coupled to only a small part of a larger bath, statistical fluctuations of the temperature (more precisely, the internal energy) of this ``sub-bath'' around the mean temperature defined by the larger bath can become significant. We show that these temperature fluctuations generally give rise to …
