Quantum Differential Privacy: An Information Theory Perspective
read the original abstract
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 as a quantum divergence. A main advantage of this approach is that differential privacy becomes a property solely based on the output states of the computation, without the need to check it for every measurement. This leads to simpler proofs and generalized statements of its properties as well as several new bounds for both, general and specific, noise models. In particular, these include common representations of quantum circuits and quantum machine learning concepts. Here, we focus on the difference in the amount of noise required to achieve certain levels of differential privacy versus the amount that would make any computation useless. Finally, we also generalize the classical concepts of local differential privacy, Renyi differential privacy and the hypothesis testing interpretation to the quantum setting, providing several new properties and insights.

Integral representations of $f$-divergences for general von Neumann algebras
The f_0-divergence defined via Jordan decomposition integrals coincides with Araki's relative entropy on arbitrary von Neumann algebras, extending Frenkel's finite-dimensional formula.

Quantum Shannon theory made robust: a tale of three protocols for almost i.i.d. sources
Robust protocols are identified for three quantum Shannon tasks under three notions of almost i.i.d. structure that preserve i.i.d. rates, along with new concepts of almost i.i.d. process and club distance.

Quantum Shannon theory made robust: a tale of three protocols for almost i.i.d. sources
Robust protocols exist for hypothesis testing, compression, and channel coding that attain optimal rates for arbitrary almost i.i.d. sources, via a new club distance and almost i.i.d. process notion.
