Quantum computing systems are moving from experimental to commercial phases, necessitating architecture-agnostic performance metrics for comparison across platforms. Researchers have proposed Peaked Random Circuits (PRCs) as a means to demonstrate quantum advantage on Near-Term Intermediate-Scale Quantum (NISQ) devices, leveraging a quantum processor's ability to detect a single, peaked output state amidst background noise. This approach enables the evaluation of system-level fidelity, a crucial metric for assessing quantum computing performance. The use of PRCs allows for a more accurate comparison of quantum systems, regardless of their underlying architecture1. As quantum developments, such as quantum advantage, narrow the timeline for cryptographic migration, the urgency for planning and implementing post-quantum cryptography (PQC) increases. This makes the evaluation of system-level fidelity using PRCs a critical step in preparing for the transition to quantum-resistant cryptographic systems, thereby ensuring the long-term security of sensitive information.
