Information causality beyond the random access code model

Baichu Yu, Valerio Scarani

The paper introduces a new quantifier for information causality based on redundant information, which closes several gaps between the principle and the quantum set of correlations,…

Fast quantum measurement tomography with optimal error bounds

Leonardo Zambrano, Sergi Ramos-Calderer, Richard Kueng

We present a two-step protocol for quantum measurement tomography that is light on classical co-processing cost and still achieves optimal sample complexity. Given measurement data…

Gaussian time-translation covariant operations: structure, implementation, and thermodynamics

Xueyuan Hu, Lea Lautenbacher, Giovanni Spaventa +3

Time-translation symmetry strongly constrains physical dynamics, yet systematic characterization for continuous-variable systems lags behind its discrete-variable counterpart. We c…

Detection of quantum entanglement across the event horizon

Patryk Michalski, Andrzej Dragan

We investigate the problem of distinguishing between separable and entangled states of two quantum wave packets, one of which falls into a black hole. Intuitively, one might expect…

Near-Optimal Parameter Tuning of Level-1 QAOA for Ising Models

V Vijendran, Dax Enshan Koh, Eunok Bae +3

The Quantum Approximate Optimisation Algorithm (QAOA) tackles combinatorial optimisation problems by encoding their solutions into the ground state of an Ising Hamiltonian prepared…

Partially smoothed information measures

Anurag Anshu, Mario Berta, Rahul Jain +1

Smooth entropies are a tool for quantifying resource trade-offs in (quantum) information theory and cryptography. In typical bi- and multi-partite problems, however, some of the su…
