Additive Resource Scaling in Quantum Circuits for Search in Cryptanalysis
Year: 2026
Type: conference-paper
Abstract: Quantum search algorithms are often analyzed in idealized, isolated models, yet real hardware and cryptanalytic applications involve communication channels and residual entanglement. We develop a unified circuit framework that models these effects explicitly, introducing a controllable quantum-channel interaction between system and environment registers. The resulting non-isolated circuits exhibit additive time-space behavior, instead of standard multiplicative scaling. We provide circuit schematics, simulation data, and performance visualization demonstrating how a single-qubit environment modifies Grover oscillations and success probability trajectories of cryptographic attacks. The proposed framework connects algorithmic tradeoffs with measurable circuit phenomena, offering a practical methodology for quantum-classical hybrid circuits design.
