Quantum Hamiltonian Identification With Classical Colored Measurement Noise

In this brief, we present a Hamiltonian-identification method for closed quantum system whose time-trace observables are measured with colored measurement noise. The dynamics of the described by Liouville equation that can be converted into coherence vector representation. Since process is disturbed classical noise, introduce an augmented model to describe total dynamics, where noise parameterized. Based on as well data, find realization unknown parameters employing eigenstate-realization algorithm. identified using transfer-function-based technique. An example two-qubit shown verify effectiveness our method.
