Resolving Structure in Prethermal Floquet Dynamics with Precision Quantum Computation
Eyal Leviatan, Tasneem Watad, Roy Perry +38
Periodically driven interacting quantum many-body systems can exhibit long-lived prethermal dynamics, where local observables retain coherent structure even as entanglement and ope…
Near-Optimal Learning of Local Lindbladians
Itai Arad, Zhili Chen, Naixu Guo +2
We study the problem of learning local Lindbladians from black-box access to the physical evolution, where the goal is to estimate all Hamiltonian and dissipative coefficients. For…
Quantum landscape tomography for efficient single-gate optimization on quantum computers
Matan Ben-Dov, Itai Arad, Emanuele G. Dalla Torre
Circuit optimization is a fundamental task for practical applications of near-term quantum computers. In this work we address this challenge through the powerful lenses of tensor n…
Reliable high-accuracy error mitigation for utility-scale quantum circuits
Dorit Aharonov, Ori Alberton, Itai Arad +36
Error mitigation is essential for unlocking the full potential of quantum algorithms and accelerating the timeline toward quantum advantage. As quantum hardware progresses to push…
Exploring the performance of superposition of product states: from 1D to 3D quantum spin systems
Apimuk Sornsaeng, Itai Arad, Dario Poletti
Tensor networks (TNs) are one of the best available tools to study many-body quantum systems. TNs are particularly suitable for one-dimensional local Hamiltonians, while their perf…
Area laws and tensor networks for maximally mixed ground states
Itai Arad, Raz Firanko, Rahul Jain
We show an area law in the mutual information for the maximally-mixed state in the ground space of general Hamiltonians, which is independent of the underlying ground space de…
