Constructing quantum many-body scar Hamiltonians from Floquet automata
Pierre-Gabriel Rozon, Michael J. Gullans, Kartiek Agarwal
We provide a systematic approach for constructing approximate quantum many-body scars (QMBS) starting from two-layer Floquet automaton circuits that exhibit trivial many-body reviv…
Colloquium: Advances in automation of quantum dot devices control
Justyna P. Zwolak, Jacob M. Taylor
Arrays of quantum dots (QDs) are a promising candidate system to realize scalable, coupled qubit systems and serve as a fundamental building block for quantum computers. In such se…
Interactive Protocols for Classically-Verifiable Quantum Advantage
Daiwei Zhu, Gregory D. Kahanamoku-Meyer, Laura Lewis +15
Achieving quantum computational advantage requires solving a classically intractable problem on a quantum device. Natural proposals rely upon the intrinsic hardness of classically…
How to engineer a quantum wavefunction
Peter W. Evans, Dominik Hangleiter, Karim P. Y. Thébault
In a conventional experiment, scientists typically aim to learn about target systems by manipulating source systems of the same material type. In an analogue quantum simulation, by…
Tight bounds on the convergence of noisy random circuits to the uniform distribution
Abhinav Deshpande, Pradeep Niroula, Oles Shtanko +3
We study the properties of output distributions of noisy, random circuits. We obtain upper and lower bounds on the expected distance of the output distribution from the "useless" u…

The National Aeronautics and Space Administration's Deep Space Quantum Link mission concept enables a unique set of science experiments by establishing robust quantum optical links…
Efficient Product Formulas for Commutators and Applications to Quantum Simulation
Yu-An Chen, Andrew M. Childs, Mohammad Hafezi +3
We construct product formulas for exponentials of commutators and explore their applications. First, we directly construct a third-order product formula with six exponentials by so…
Two-qubit silicon quantum processor with operation fidelity exceeding 99%
A. R. Mills, C. R. Guinn, M. J. Gullans +4
Silicon spin qubits satisfy the necessary criteria for quantum information processing. However, a demonstration of high fidelity state preparation and readout combined with high fi…
Hamiltonian simulation with random inputs
Qi Zhao, You Zhou, Alexander F. Shaw +2
The algorithmic error of digital quantum simulations is usually explored in terms of the spectral norm distance between the actual and ideal evolution operators. In practice, this…
Negative quasiprobabilities enhance phase estimation in quantum-optics experiment
Noah B. Lupu-Gladstein, Batuhan Y. Yilmaz, David R. M. Arvidsson-Shukur +4
Operator noncommutation, a hallmark of quantum theory, limits measurement precision, according to uncertainty principles. Wielded correctly, though, noncommutation can boost precis…
Generalization in quantum machine learning from few training data
Matthias C. Caro, Hsin-Yuan Huang, M. Cerezo +4
Modern quantum machine learning (QML) methods involve variationally optimizing a parameterized quantum circuit on a training data set, and subsequently making predictions on a test…
