A Heterogeneous Distributed Architecture for Quantum Simulation
John Stack, Sitong Liu, Abhinav Anand +6
Architectural specialization and distribution can help scale fault-tolerant quantum computers, but may also introduce substantial overheads from communication, routing, and resourc…
Learning and Generating Mixed States Prepared by Shallow Channel Circuits
Fangjun Hu, Christian Kokail, Milan KornjaÄa +5
Learning quantum states from measurement data is a central problem in quantum information and computational complexity. In this work, we study the problem of learning to generate m…
Towards Deploying Optimistic Quantum Fourier Transforms: An Architecture-Algorithm Co-Design Study
Pedro L. S. Lopes
We present an architecture-algorithm co-design study of the Optimistic Quantum Fourier Transform (OQFT) under a surface-code fault-tolerant execution model for reconfigurable neutr…
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…
