Efficient Quantum Measurements: Computational Max-and Measured Rényi Divergences and Applications
Quantum information processing is limited, in practice, to efficiently implementable operations. This motivates the study of quantum …

Catalytic Activation of Bell Nonlocality
The correlations of certain entangled states can be perfectly simulated classically via a local model. Hence such states are termed …

Robustly self-testing all maximally entangled states in every finite dimension
We establish a device-independent, noise-tolerant certification of maximally entangled states in every finite dimension $d$. The core …

Strict hierarchy between $n$-wise measurement simulability, compatibility structures, and multi-copy compatibility
The incompatibility of quantum measurements, i.e. the fact that certain observable quantities cannot be measured jointly is widely …

A complexity transition in displaced Gaussian Boson sampling
Abstract Gaussian Boson Sampling (GBS) is the problem of sampling from the output of photon-number-resolving measurements of squeezed …
