The cost of classically simulating quantum communication is as high as it could be
Riccardo Castellano, Pavel Sekatski, Nicolas Brunner
A long-standing open question is to characterize the classical communication cost of simulating the correlations arising from measurements on finite-dimensional quantum systems. We…
Quantifying the fidelity of a quantum memory
Victor Barizien, Sophie Egelhaaf, Angelo Gelmini Rodriguez +5
Quantum memories are key ingredients for future quantum networks. Developing methods for their certification is therefore an important, yet challenging, problem. In this work, we p…
The bottleneck dimension of quantum operations
Pavel Sekatski
Programmable quantum devices nominally act on a Hilbert space whose dimension grows exponentially with the number of constituents, but the presence of noise makes it unlikely that…
Entanglement distribution and quantum storage of more than 8000 modes over a metropolitan network
Angelo Gelmini Rodriguez, Louis Nicolas, Théo Sanchez Mejia +6
Entanglement generation between telecommunication photons and matter is central to fibre-based quantum repeaters. Achieving practical communication rates requires multiplexing, whi…
Hybrid Quantum Neural Networks: Theory, Implementations, and Applications
Léo Monbroussou, Maniraman Periyasamy, Viacheslav Kuzmin +4
Artificial intelligence has been transformed by deep neural networks, yet the search for new learning architectures continues. Quantum machine learning offers one such direction, a…
Self-testing Quantum Supermaps
Victor Barizien, Cyril Branciard, Alastair A. Abbott +2
By certifying quantum operations from measurement statistics directly, without any assumption on the internal workings of the devices involved, self-testing enables a uniquely reli…
Certification of the genuine resolution of photon number resolving detectors
Jef Pauwels, Towsif Taher, Roope Uola +3
Photon-number-resolving (PNR) detectors are essential components of photonic quantum technologies, yet thus far, no practical metric exists to certify how many photons they can gen…
Superactivation of genuine multipartite Bell nonlocality from two-party entanglement
Markus Miethlinger, Riccardo Castellano, Pavel Sekatski +1
Characterizing the relation between entanglement and Bell nonlocality is a long-standing open problem, notably challenging in the multipartite case. Here we investigate the effect…
Information plane and compression-gnostic feedback in quantum machine learning
Nathan Haboury, Mo Kordzanganeh, Alexey Melnikov +1
The information plane (Tishby et al. arXiv:physics/0004057, Shwartz-Ziv et al. arXiv:1703.00810) has been proposed as an analytical tool for studying the learning dynamics of neura…
An exponentially-growing family of universal quantum circuits
Mo Kordzanganeh, Pavel Sekatski, Leonid Fedichkin +1
Quantum machine learning has become an area of growing interest but has certain theoretical and hardware-specific limitations. Notably, the problem of vanishing gradients, or barre…
