Quantum Information Causality [PDF]
Physical Review Letters, 2013 How much information can a transmitted physical system fundamentally communicate? We introduce the principle of quantum information causality, which states the maximum amount of quantum information that a quantum system can communicate as a function of its dimension, independently of any previously shared quantum physical resources.

Distribution of high-dimensional entanglement via an intra-city free-space link
Nature Communications, 2017 Increasing the dimensionality of entangled states improves robustness and capacity of secure quantum communications, but it requires suitably modified setups.

Quantum Information Elicitation
Proceedings of the 24th ACM Conference on Economics and Computation, 2023 In the classic scoring rule setting, a principal incentivizes an agent to truthfully report their probabilistic belief about some future outcome. This paper addresses the situation when this private belief, rather than a classical probability distribution, is instead a quantum mixed state.

Relationship between Information Scrambling and Quantum Darwinism
, 2023 A quantum system interacting with a multipartite environment can induce redundant encoding of the information of a system into the environment, which is the essence of quantum Darwinism.

Quantum information theory and the foundations of quantum mechanics
, 2004 This thesis is a contribution to the debate on the implications of quantum information theory for the foundational problems of quantum mechanics. In Part I an attempt is made to shed some light on the nature of information and quantum information theory.

Noiseless photonic non-reciprocity via optically-induced magnetization
Nature Communications, 2021 Optical nonreciprocity through magneto-optical effects requires bulky apparatuses and strong magnetic fields, while magnetic-free approaches are difficult to implement. Here, the authors use optically-induced magnetisation in an atomic ensemble to get 50

Persistence of quantum information [PDF]
Physics Letters A, 2007 There is an increasing interest in the role of macroscopic environments to our understanding of the basics of quantum theory. The knowledge of the implications of the quantum theory to other theories, especially to the statistical mechanics and the domain of validity has captivated scientists from the beginning of quantum description. In such a context,

Single ion qubit with estimated coherence time exceeding one hour
Nature Communications, 2021 Extending qubit coherence times represent one of the key challenges for quantum technologies. Here, after properly suppressing magnetic-field fluctuations, frequency instability and leakage of the microwave reference-oscillator, the authors infer ...
