Fast and Parallel High-Rate STAR Architecture for Megaquop Quantum Simulation
Refaat Ismail, Milan Kornjača, Hong-Ye Hu +4
Fault-tolerant quantum simulation is approaching a phase where encoding overhead, logical Clifford operations, magic-state preparation, and rotation synthesis must be optimized tog…
Opportunities and challenges in scaling quantum error detection on hardware
Yanis Le Fur, Ethan Egger, Hong-Ye Hu +3
Quantum error detection can produce unbiased expectation values that exponentially converge to noiseless results as the code distance is increased. Despite this, its performance as…
Model-agnostic cooling algorithms for strongly interacting fermions
Henning Schlömer, Liyuan Chen, Susanne F. Yelin +1
Strongly interacting fermions underpin some of the most challenging problems in condensed matter physics, such as high-temperature superconductivity. The low-energy states of these…
Entanglement and information scrambling in long-range measurement-only circuits
Abigail McClain Gomez, Fiona Abney-McPeek, Hong-Ye Hu +2
Measurement-only circuits provide a minimal setting in which repeated local projections can either generate or suppress many-body entanglement, giving rise to measurement-induced p…
Ansatz-Free Learning of Lindbladian Dynamics In Situ
Petr Ivashkov, Nikita Romanov, Weiyuan Gong +3
Characterizing the dynamics of open quantum systems at the level of microscopic interactions and error mechanisms is essential for calibrating quantum hardware, designing robust si…
Universal Dynamics with Globally Controlled Analog Quantum Simulators
Hong-Ye Hu, Abigail McClain Gomez, Liyuan Chen +6
Analog quantum simulators with global control fields have emerged as powerful platforms for exploring complex quantum phenomena. Despite these advances, a fundamental theoretical q…
