Short Paper: Device- and Locality-Specific Fingerprinting of Shared NISQ Quantum Computers. (arXiv:2202.12731v1 [cs.CR])

Fingerprinting of quantum computer devices is a new threat that poses a
challenge to shared, cloud-based quantum computers. Fingerprinting can allow
adversaries to map quantum computer infrastructures, uniquely identify
cloud-based devices which otherwise have no public identifiers, and it can
assist other adversarial attacks. This work shows idle tomography-based
fingerprinting method based on crosstalk-induced errors in NISQ quantum
computers. The device- and locality-specific fingerprinting results show
prediction accuracy values of $99.1\%$ and $95.3\%$, respectively.
