From Bell Products to Greenberger-Horne-Zeilinger states: Quantum Memories via emergent Hamiltonians
Anubhab Sur, Qiujiang Guo, Rubem Mondaini
With the advent of exquisite quantum emulators, storing highly entangled many-body states becomes essential. While entanglement typically builds over time when evolving a quantum s…
Fock space prethermalization and time-crystalline order on a quantum processor
Zehang Bao, Zitian Zhu, Yang-Ren Liu +31
Periodically driven quantum many-body systems exhibit a wide variety of exotic nonequilibrium phenomena and provide a promising pathway for quantum applications. A fundamental chal…
Onset of Quantum Chaos and Ergodicity in Spin Systems with Highly Degenerate Hilbert Spaces
Mahmoud Abdelshafy, Rubem Mondaini, Marcos Rigol
We show that in systems with highly degenerate energy spectra, such as the 2D transverse-field Ising model (2DTFIM) in the strong-field limit, quantum chaos can emerge in finite sy…
Observation of Quantum Darwinism and the Origin of Classicality with Superconducting Circuits
Zitian Zhu, Kiera Salice, Akram Touil +9
The transition from quantum to classical behavior is a central question in modern physics. How can we rationalize everyday classical observations from an inherently quantum world?…
Quantum highway: Observation of minimal and maximal speed limits for few and many-body states
Zitian Zhu, Lei Gao, Zehang Bao +30
Tracking the time evolution of a quantum state allows one to verify the thermalization rate or the propagation speed of correlations in generic quantum systems. Inspired by the ene…
Quantum State Transfer in Interacting, Multiple-Excitation Systems
Alexander Yue, Rubem Mondaini, Qiujiang Guo +1
Quantum state transfer (QST) describes the coherent passage of quantum information from one node in a network to another. Experiments on QST span a diverse set of platforms and cur…
