Quantum probing beyond pure dephasing

25 Aug 2020 Tamascelli Dario Benedetti Claudia Breuer Heinz-Peter Paris Matteo G. A.

Quantum probing is the art of exploiting simple quantum systems interacting with a complex environment to extract precise information about some environmental parameters, e.g. the temperature of the environment or its spectral density. Here we analyze the performance of a single-qubit probe in characterizing Ohmic bosonic environments at thermal equilibrium... (read more)
