A fidelity-driven approach to quantum circuit partitioning via weighted hypergraphs for noise-resilient computation

Awad Wehbe, Safiya Al Khatib, Abdel-Mehsen Ahmad·Jun 7, 2025

Effective circuit partitioning is critical for Noisy Intermediate-Scale Quantum (NISQ) devices, which are hampered by high error rates and limited qubit connectivity. Standard partitioning heuristics often neglect gate-specific error impacts, leading...

State Dependent Optimization with Quantum Circuit Cutting

Xinpeng Li, Ji Liu, Jeffrey M. Larson +4 more·Jun 6, 2025

Quantum circuits can be reduced through optimization to better fit the constraints of quantum hardware. One such method, initial-state dependent optimization (ISDO), reduces gate count by leveraging knowledge of the input quantum states. Surprisingly...

Transient and steady-state chaos in dissipative quantum systems

Debabrata Mondal, Lea F. Santos, S. Sinha·Jun 5, 2025

Dissipative quantum chaos plays a central role in the characterization and control of information scrambling, non-unitary evolution, and thermalization, but it still lacks a precise definition. The Grobe-Haake-Sommers conjecture, which links Ginibre ...
