Unboxing Quantum Black Box Models: Learning Non-Markovian Dynamics
Stefan Krastanov, Kade Head-Marsden, Sisi Zhou +3
Characterizing the memory properties of the environment has become critical for the high-fidelity control of qubits and other advanced quantum systems. However, current non-Markovi…
Asymptotic theory of quantum channel estimation
Sisi Zhou, Liang Jiang
The quantum Fisher information (QFI), as a function of quantum states, measures the amount of information that a quantum state carries about an unknown parameter. The (entanglement…
An exact correspondence between the quantum Fisher information and the Bures metric
Sisi Zhou, Liang Jiang
The quantum information and the Bures metric are equivalent to each other, except at points where the rank of the density matrix changes. Here we show that by slightly modifying th…
Optimal approximate quantum error correction for quantum metrology
Sisi Zhou, Liang Jiang
For a generic set of Markovian noise models, the estimation precision of a parameter associated with the Hamiltonian is limited by the scaling where is the total p…
Optimal probes and error-correction schemes in multi-parameter quantum metrology
Wojciech Gorecki, Sisi Zhou, Liang Jiang +1
We derive a necessary and sufficient condition for the possibility of achieving the Heisenberg scaling in general adaptive multi-parameter estimation schemes in presence of Markovi…
Stochastic Estimation of Dynamical Variables
Stefan Krastanov, Sisi Zhou, Steven T. Flammia +1
Estimating the parameters governing the dynamics of a system is a prerequisite for its optimal control. We present a simple but powerful method that we call STEADY, for STochastic…
