Heisenberg Echo Symmetrization for Gate-Insertion Error Mitigation
Raam Uzdin
Gate insertion (GI) quantum error mitigation replaces involutory gates such as CZ and CX with 2j+1 repetitions of the same gates to nominally amplify noise by the same factor. Anal…
Orders of magnitude sampling overhead reduction in quantum error mitigation
Raam Uzdin
Quantum error mitigation (QEM) infers noiseless expectation values from noisy variants of a target quantum circuit. Unlike quantum error correction, QEM requires no additional hard…
Drift-resilient mid-circuit measurement and state preparation error mitigation for dynamic circuits
Jader P. Santos, Raam Uzdin
Quantum error mitigation (QEM) for dynamic circuits, i.e., those incorporating mid-circuit measurements and feedforward, is important for two key reasons. First, quantum error corr…

We present methods for evaluating the rate of change in quantities during quantum evolution due to coupling to the environment (dissipation hereafter). The protocol is based on rep…
Thermometric machine for ultraprecise thermometry of low temperatures
Ivan Henao, Karen V. Hovhannisyan, Raam Uzdin
Thermal equilibrium states are exponentially hard to distinguish at very low temperatures, making equilibrium quantum thermometry in this regime a formidable task. We present a the…

Tanmoy Pandit, Alaina M. Green, C. Huerta Alderete +2
Periodically-driven systems are ubiquitous in science and technology. In quantum dynamics, even a small number of periodically-driven spins leads to complicated dynamics. Hence, it…
