Entanglement in quantum spin chains is strictly finite at any temperature
Ainesh Bakshi, Soonwon Choi, Saúl Pilatowsky-Cameo
Entanglement is the hallmark of quantum physics, yet its characterization in interacting many-body systems at thermal equilibrium remains one of the most important challenges in qu…
Measuring gravitational lensing time delays with quantum information processing
Zhenning Liu, William DeRocco, Shiming Gu +6
The gravitational fields of astrophysical bodies bend the light around them, creating multiple paths along which light from a distant source can arrive at Earth. Measuring the diff…
The vast world of quantum advantage
Hsin-Yuan Huang, Soonwon Choi, Jarrod R. McClean +1
The quest to identify quantum advantages lies at the heart of quantum technology. While quantum devices promise extraordinary capabilities, from exponential computational speedups…
2D Quon Language: Unifying Framework for Cliffords, Matchgates, and Beyond
Byungmin Kang, Chen Zhao, Zhengwei Liu +2
Simulating generic quantum states and dynamics is practically intractable using classical computers. However, certain special classes -- namely Clifford and matchgate circuits -- p…
Quantum Computing Enhanced Sensing
Richard R. Allen, Francisco Machado, Isaac L. Chuang +2
Quantum computing and quantum sensing represent two distinct frontiers of quantum information science. In this work, we harness quantum computing to solve a fundamental and practic…
Quantum Algorithm to Prepare Quasi-Stationary States
Samuel J. Garratt, Soonwon Choi
Quantum dynamics can be analyzed via the structure of energy eigenstates. However, in the many-body setting, preparing eigenstates associated with finite temperatures requires time…
