Constructive interference at the edge of quantum ergodic dynamics
Dmitry A. Abanin, Rajeev Acharya, Laleh Aghababaie-Beni +262
Quantum observables in the form of few-point correlators are the key to characterizing the dynamics of quantum many-body systems. In dynamics with fast entanglement generation, qua…
Experimentally Informed Decoding of Stabilizer Codes Based on Syndrome Correlations
Ants Remm, Nathan Lacroix, Lukas Bödeker +9
High-fidelity decoding of quantum error correction codes relies on an accurate experimental model of the physical errors occurring in the device. Because error probabilities can de…
Scaling and logic in the color code on a superconducting quantum processor
Nathan Lacroix, Alexandre Bourassa, Francisco J. H. Heras +212
Quantum error correction is essential for bridging the gap between the error rates of physical devices and the extremely low logical error rates required for quantum algorithms. Re…
Quantum optimal control of superconducting qubits based on machine-learning characterization
Elie Genois, Noah J. Stevenson, Noah Goss +2
Implementing fast and high-fidelity quantum operations using open-loop quantum optimal control relies on having an accurate model of the quantum dynamics. Any deviations between th…
Characterizing Coherent Errors using Matrix-Element Amplification
Jonathan A. Gross, Elie Genois, Dripto M. Debroy +4
Repeating a gate sequence multiple times amplifies systematic errors coherently, making it a useful tool for characterizing quantum gates. However, the precision of such an approac…
Optimal control in large open quantum systems: the case of transmon readout and reset
Ronan Gautier, Élie Genois, Alexandre Blais
We present a framework that combines the adjoint-state method together with reverse-time backpropagation to solve prohibitively large open-system quantum control problems. Our appr…
Stable Quantum-Correlated Many Body States through Engineered Dissipation

Engineered dissipative reservoirs have the potential to steer many-body quantum systems toward correlated steady states useful for quantum simulation of high-temperature supercondu…
Phase transition in Random Circuit Sampling
A. Morvan, B. Villalonga, X. Mi +182
Undesired coupling to the surrounding environment destroys long-range correlations on quantum processors and hinders the coherent evolution in the nominally available computational…
Context Aware Fidelity Estimation
Dripto M. Debroy, Elie Genois, Jonathan A. Gross +6
We present Context Aware Fidelity Estimation (CAFE), a framework for benchmarking quantum operations that offers several practical advantages over existing methods such as Randomiz…
Realizing Repeated Quantum Error Correction in a Distance-Three Surface Code
Sebastian Krinner, Nathan Lacroix, Ants Remm +13
Quantum computers hold the promise of solving computational problems which are intractable using conventional methods. For fault-tolerant operation quantum computers must correct e…
Quantum-tailored machine-learning characterization of a superconducting qubit
Élie Genois, Jonathan A. Gross, Agustin Di Paolo +5
Machine learning (ML) is a promising approach for performing challenging quantum-information tasks such as device characterization, calibration and control. ML models can train dir…
Fast and differentiable simulation of driven quantum systems
Ross Shillito, Jonathan A. Gross, Agustin Di Paolo +2
The controls enacting logical operations on quantum systems are described by time-dependent Hamiltonians that often include rapid oscillations. In order to accurately capture the r…
