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…

Adaptive t Design Dummy-Gate Obfuscation for Cryogenic Scale Enforcement

Samuel Punch, Krishnendu Guha

Cloud quantum services can reveal circuit structure and timing through scheduler metadata, latency patterns, and co-tenant interference. We introduce NADGO (Noise-Adaptive Dummy-Ga…

MAESTROCUT: Dynamic, Noise-Adaptive, and Secure Quantum Circuit Cutting on Near-Term Hardware

Samuel Punch, Krishnendu Guha

We present MaestroCut, a closed-loop framework for quantum circuit cutting that adapts partitioning and shot allocation to device drift and workload variation. MaestroCut tracks a…

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…
