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

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.
