Witnessing quantum memory in dynamics using quantum processors — •Krishna Palaparthy, Charlotte Bäcker, and Walter Strunz — TUD Dresden University of Technology, Dresden, Germany

Quantum simulations on noisy quantum computers can help us understand the role of quantum memory in quantum dynamics, for quantum computations and information processing tasks. To demonstrate local disclosure of quantum memory on the NISQ quantum processors, our simulation makes use of a collision model of sequentially applied two-qubit unitaries realizing the dynamics of a non-Markovian amplitude-damping channel. We investigate the relaxation dynamics and its influence on the entanglement dynamics with ancilla that are crucial for the proof of quantum memory.
