This research introduces a novel optical reset model using time-bin interferometers to dynamically control quantum circuits based on classical measurement history. By synchronizing these optical operations with classical memory devices, the study significantly reduces uncertainty in future measurements, offering a viable path for dynamical circuits beyond current superconducting hardware. The work identifies specific information-theoretic measures for multi-time correlations and proposes applications ranging from boson sampling to experimental tests of Landauer's principle.
Quantum-optical reset with classical memory
arXiv:2509.02980v3 Announce Type: replace Abstract: Dynamic quantum circuits generate states that depend on the measurement results obtained during circuit execution. To date such a quantum computing model has mainly been implemented with qubit-based superconducting hardware utilizing reset operations and classical logic. Here we develop a model of optical reset by using time-bin self-looped interferometers demonstrated in recent experiments. Synchronizing the optical reset with a simple classical device storing history of measurement results allows one to decrease uncertainty of future measurements, which suggests new possibilities for constructing dynamical circuits on optical platforms. Information flow with significant multi-time correlations and memory depth is identified through distinct information-theoretic measures. We discuss potential applications of the proposed reset model, including the realization of boson sampling and experimental tests of the quantum-mechanical formulation of Landauer's principle.
