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…
Stronger Welch Bounds and Optimal Approximate -Designs
Riccardo Castellano, Dmitry Grinko, Sadra Boreiri +2
The question of how well a finite ensemble of quantum states can approximate Haar randomness is relevant in many areas of quantum physics. Here we consider this problem from a geom…
A Quantum Mechanical Pendulum Clock
Matteo Brunelli, Mohammad Mehboudi, Nicolas Brunner +1
We investigate an optomechanical system as a model of an autonomous mechanical pendulum clock in the quantum regime, whose operation relies only on incoherent (thermal) resources.…
Symmetric observations without symmetric causal explanations
Christian William, Patrick Remy, Jean-Daniel Bancal +3
Inferring causal models from observed correlations is a challenging task, crucial to many areas of science. In order to alleviate the computational effort when sifting through poss…
Certifying high-dimensional quantum channels
Sophie Engineer, Suraj Goel, Sophie Egelhaaf +9
The use of high-dimensional systems for quantum communication opens interesting perspectives, such as increased information capacity and noise resilience. In this context, it is cr…
Virtual qubits, virtual temperatures, and the foundations of thermodynamics
Nicolas Brunner, Noah Linden, Sandu Popescu +1
We argue that thermal machines can be understood from the perspective of `virtual qubits' at `virtual temperatures': The relevant way to view the two heat baths which drive a therm…
