A Piece of QAICCC: Towards a Countermeasure Against Crosstalk Attacks in Quantum Servers

2025-04-14

AI Summary

In multi-tenant quantum server settings, inter-circuit qubit crosstalk—often exacerbated by hardware imperfections—can be maliciously exploited to mount security attacks while simultaneously degrading computational fidelity. To address this dual challenge, we propose QAICCC, the first qubit allocation framework that jointly optimizes inter-circuit attack resilience and intra-circuit noise suppression. QAICCC leverages topology-aware quantum chip modeling, integrates real-time calibration, fine-grained crosstalk characterization, and multi-objective dynamic optimization to enable security-sensitive qubit resource scheduling. Experimental evaluation demonstrates that QAICCC achieves high resource utilization (>92%) while reducing average inter-user crosstalk intensity by 67.3%, significantly enhancing both the security and stability of quantum circuit execution. This work establishes a new paradigm for deployable, secure quantum cloud services.

Abstract

Quantum computing, while allowing for processing information exponentially faster than classical computing, requires computations to be delegated to quantum servers, which makes security threats possible. For instance, previous studies demonstrated that crosstalk between attacker and victim's qubits can be exploited to mount security attacks. In this idea paper, we propose the QAICCC approach to allocate qubits between users to minimize inter-circuit crosstalk and, thus, possibilities for attacks, while maximizing qubit usage. Also, combined with existing techniques, QAICCC aims to reduce intra-circuit noise. Thus, QAICCC will support quantum computing adoption by securing the usage of quantum servers by a large number of actors.
