Quantum Differential Privacy: An Information Theory Perspective. (arXiv:2202.10717v2 [quant-ph] UPDATED)

Differential privacy has been an exceptionally successful concept when it
comes to providing provable security guarantees for classical computations.
More recently, the concept was generalized to quantum computations. While
classical computations are essentially noiseless and differential privacy is
often achieved by artificially adding noise, near-term quantum computers are
inherently noisy and it was observed that this leads to natural differential
privacy as a feature. In this work we discuss quantum differential privacy in
an information theoretic framework by casting it …
