Unified Probe of Quantum Chaos and Ergodicity from Hamiltonian Learning
Nik O. Gjonbalaj, Christian Kokail, Susanne F. Yelin +1
Developing measures of quantum ergodicity and chaos stands as a foundational task in the study of quantum many-body systems. In this work, we propose metrics for these effects base…
Engineering quantum criticality and dynamics on an analog-digital simulator
Alexandra A. Geim, Nazli Ugur Koyluoglu, Simon J. Evered +14
Understanding emergent phenomena in out-of-equilibrium interacting many-body systems is an exciting frontier in physical science. While quantum simulators represent a promising app…
A New Angle on Quantum Subspace Diagonalization for Quantum Chemistry
Xeno De Vriendt, Jacob Bringewatt, Nik O. Gjonbalaj +5
Quantum subspace diagonalization and quantum Krylov algorithms offer a feasible, pre- or early-fault tolerant alternative to quantum phase estimation for using quantum computers to…
Shortcuts to Analog Preparation of Non-Equilibrium Quantum Lakes
Nik O. Gjonbalaj, Rahul Sahay, Susanne F. Yelin
The dynamical preparation of exotic many-body quantum states is a persistent goal of analog quantum simulation, often limited by experimental coherence times. Recently, it was show…
Modifying cooperative decay via disorder in atom arrays
Nik O. Gjonbalaj, Stefan Ostermann, Susanne F. Yelin
Atomic arrays can exhibit collective light emission when the transition wavelength exceeds their lattice spacing. Subradiant states take advantage of this phenomenon to drastically…
