Reversing Lindblad Dynamics via Continuous Petz Recovery Map

Understand

An important issue in developing quantum technology is that quantum states are so sensitive to noise.

• We propose a protocol that introduces reverse dynamics, in order to precisely control quantum systems against noise described by the Lindblad master equation.
• The reverse dynamics can be obtained by constructing the Petz recovery map in continuous time.
• By providing the exact form of the Hamiltonian and jump operators for the reverse dynamics, we explore the potential of utilizing the near-optimal recovery of the Petz map in controlling noisy quantum dynamics.
