Information Propagation in Rydberg Arrays via Analog OTOC Calculations
Goksu Can Toga, Siva Darbha, Ermal Rrapaj +2
Out-of-time-order correlators (OTOCs) are the main tool for probing quantum chaos and scrambling, and have become crucial probes in many areas of quantum computing. However, the me…
Observation of an anomaly in the statistics of Kibble-Zurek defects
Jan Balewski, Alexey Khudorozhkov, Siva Darbha +8
The Kibble-Zurek mechanism quantifies defect formation during adiabatic passage across a continuous phase transition, providing key insights into universality in quantum many-body…
Probing emergent prethermal dynamics and resonant melting on a programmable quantum simulator
Siva Darbha, Alexey Khudorozhkov, Pedro L. S. Lopes +11
The dynamics of isolated quantum systems following a sudden quench plays a central role in many areas of material science, high-energy physics, and quantum chemistry. Featuring com…
Quantum Computing Technology Roadmaps and Capability Assessment for Scientific Computing -- An analysis of use cases from the NERSC workload
Daan Camps, Ermal Rrapaj, Katherine Klymko +6
The National Energy Research Scientific Computing Center (NERSC), as the high-performance computing (HPC) facility for the Department of Energy's Office of Science, recognizes the…
Estimating Eigenenergies from Quantum Dynamics: A Unified Noise-Resilient Measurement-Driven Approach
Yizhi Shen, Daan Camps, Aaron Szasz +5
Ground state energy estimation in physical, chemical, and materials sciences is one of the most promising applications of quantum computing. In this work, we introduce a new hybrid…
Long-lived oscillations of metastable states in neutral atom systems
Siva Darbha, Milan KornjaÄa, Fangli Liu +7
Metastable states arise in a range of quantum systems and can be observed in various dynamical scenarios, including decay, bubble nucleation, and long-lived oscillations. The pheno…
