Robust self testing of the 3-qubit state
Xingyao Wu, Yu Cai, Tzyh Haur Yang +3
Self-testing is a device independent method which can be used to determine the nature of a physical system or device, without knowing any detail of the inner mechanism or the physi…
Robust and versatile black-box certification of quantum devices
Tzyh Haur Yang, Tamás Vértesi, Jean-Daniel Bancal +2
Self-testing refers to the fact that, in some quantum devices, both states and measurements can be assessed in a black-box scenario, on the sole basis of the observed statistics, i…
Physical characterization of quantum devices from nonlocal correlations
Jean-Daniel Bancal, Miguel Navascués, Valerio Scarani +2
In the device-independent approach to quantum information theory, quantum systems are regarded as black boxes which, given an input (the measurement setting), return an output (the…
Robust Self Testing of Unknown Quantum Systems into Any Entangled Two-Qubit States
Tzyh Haur Yang, Miguel Navascues
Self testing is a device independent approach to estimate the state and measurement operators, without the need to assume the dimension of our quantum system. In this paper, we sho…
Robust Self Testing of the Singlet
Matthew McKague, Tzyh Haur Yang, Valerio Scarani
In this paper, we introduce a general framework to study the concept of robust self testing which can be used to self test EPR pairs and local measurement operators. The result is…
Information Causality and Extremal Tripartite Correlations
Tzyh Haur Yang, Daniel Cavalcanti, Mafalda Almeida +2
We study the principle of information causality for the set of extremal correlations in the tripartite scenario. We show that all but one nonlocal extremal correlations in this sce…
