Balanced Routing for Symmetric Quantum Circuits
Samuel Punch
Mapping quantum programs to restricted physical chips requires SWAP operations, incurring depth and error penalties. In symmetric programs, this routing overhead breaks theoretical…

Post-Cut Metadata Inference Attacks on Quantum Circuit Cutting Pipelines
Samuel Punch, Krishnendu Guha, Utz Roedig
Quantum cloud providers can identify a user's algorithm and secret problem structure without ever seeing actual quantum data, simply by analyzing routine metadata collected for bil…

Simulating Mass-Dependent Decoherence in Quantum Computers: Baseline Signatures for Testing Gravity-Induced Collapse
Viswak R Balaji, Samuel Punch
We present a quantum computing simulation study of mass-dependent decoherence models inspired by Penrose's gravity-induced collapse hypothesis. According to objective reduction (OR…
