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…
Can apparent superluminal neutrino speeds be explained as a quantum weak measurement?
M. V. Berry, N. Brunner, S. Popescu +1
Probably not.
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…
