Bulk and Boundary Quantum Phase Transitions in a Square Rydberg Atom Array
Marcin Kalinowski, Rhine Samajdar, Roger G. Melko +3
Motivated by recent experimental realizations of exotic phases of matter on programmable quantum simulators, we carry out a comprehensive theoretical study of quantum phase transit…
Limitations of Linear Cross-Entropy as a Measure for Quantum Advantage
Xun Gao, Marcin Kalinowski, Chi-Ning Chou +3
Demonstrating quantum advantage requires experimental implementation of a computational task that is hard to achieve using state-of-the-art classical systems. One approach is to pe…
Exact emergent quantum state designs from quantum chaotic dynamics
Wen Wei Ho, Soonwon Choi
We present exact results on a novel kind of emergent random matrix universality that quantum many-body systems at infinite temperature can exhibit. Specifically, we consider an ens…
Classical Shadow Tomography with Locally Scrambled Quantum Dynamics
Hong-Ye Hu, Soonwon Choi, Yi-Zhuang You
We generalize the classical shadow tomography scheme to a broad class of finite-depth or finite-time local unitary ensembles, known as locally scrambled quantum dynamics, where the…
The Measurement-induced Transition in Long-range Interacting Quantum Circuits
Maxwell Block, Yimu Bao, Soonwon Choi +2
The competition between scrambling unitary evolution and projective measurements leads to a phase transition in the dynamics of quantum entanglement. Here, we demonstrate that the…
Classically-Verifiable Quantum Advantage from a Computational Bell Test
Gregory D. Kahanamoku-Meyer, Soonwon Choi, Umesh V. Vazirani +1
We propose and analyze a novel interactive protocol for demonstrating quantum computational advantage, which is efficiently classically verifiable. Our protocol relies upon the cry…
