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…
Non-Abelian Quantum Low-Density Parity Check Codes and Non-Clifford Operations from Gauging Logical Gates via Measurements
Maine Christos, Chiu Fan Bowen Lo, Vedika Khemani +1
In this work, we introduce constructions for non-Abelian qLDPC codes obtained by gauging transversal Clifford gates using measurement and feedback. In particular, we identify two q…
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…
Classifying One-Dimensional Quantum States Prepared by a Single Round of Measurements
Rahul Sahay, Ruben Verresen
Measurements and feedback have emerged as powerful resources for creating many-body quantum states. However, a detailed understanding has been restricted to fixed-point representat…
Finite-Depth Preparation of Tensor Network States from Measurement
Rahul Sahay, Ruben Verresen
Although tensor network states constitute a broad range of exotic quantum states, their realization is challenging and often requires resources whose depth scales with system size.…
