Noise-robust proofs of quantum network nonlocality
Sadra Boreiri, Bora Ulu, Nicolas Brunner +1
Quantum networks allow for novel forms of quantum nonlocality. By exploiting the combination of entangled states and entangled measurements, strong nonlocal correlations can be gen…
Custom Bell inequalities from formal sums of squares
Victor Barizien, Pavel Sekatski, Jean-Daniel Bancal
Bell inequalities play a key role in certifying quantum properties for device-independent quantum information protocols. It is still a major challenge, however, to devise Bell ineq…
Towards the device-independent certification of a quantum memory
Pavel Sekatski, Jean-Daniel Bancal, Marie Ioannou +2
Quantum memories represent one of the main ingredients of future quantum communication networks. Their certification is therefore a key challenge. Here we develop efficient certifi…
Calibration-Independent Certification of a Quantum Frequency Converter
Matthias Bock, Pavel Sekatski, Jean-Daniel Bancal +5
We report on a method to certify a unitary operation with the help of source and measurement apparatuses whose calibration throughout the certification process needs not be trusted…
Compatibility of projective measurements subject to white noise and loss
Pavel Sekatski
It is well known that when two or more quantum measurements suffer from imperfections they may lose their incompatibility. For a quantum system of finite dimension d we study the i…
Unlimited One-Way Steering
Pavel Sekatski, Florian Giraud, Roope Uola +1
This work explores the asymmetry of quantum steering in a setup using high-dimensional entanglement. We construct entangled states with the following properties: one party (A…
