Avoiding local minima in Variational Quantum Algorithms with Neural Networks
Javier Rivera-Dean, Patrick Huembeli, Antonio Acín +1
Variational Quantum Algorithms have emerged as a leading paradigm for near-term quantum computation. In such algorithms, a parameterized quantum circuit is controlled via a classic…
The original Wigner's friend paradox within a realist toy model
Matteo Lostaglio, Joseph Bowles
The original Wigner's friend paradox is a gedankenexperiment involving an observer described by an external agent. The paradox highlights the tension between unitary evolution and…
Experimental robust self-testing of the state generated by a quantum network
Iris Agresti, Beatrice Polacchi, Davide Poderini +7
Self-testing is a method of quantum state and measurement estimation that does not rely on assumptions about the inner working of the used devices. Its experimental realization has…
Bounding sets of sequential quantum correlations and device-independent randomness certification
Joseph Bowles, Flavio Baccari, Alexia Salavrakos
An important problem in quantum information theory is that of bounding sets of correlations that arise from making local measurements on entangled states of arbitrary dimension. Cu…
Device-independent certification of tensor products of quantum states using single-copy self-testing protocols
Ivan Šupić, Daniel Cavalcanti, Joseph Bowles
Self-testing protocols are methods to determine the presence of shared entangled states in a device independent scenario, where no assumptions on the measurements involved in the p…
Self-testing of quantum systems: a review
Ivan Šupić, Joseph Bowles
Self-testing is a method to infer the underlying physics of a quantum experiment in a black box scenario. As such it represents the strongest form of certification for quantum syst…
