Certification of non-classicality in all links of a photonic star network without assuming quantum mechanics
Ning-Ning Wang, Alejandro Pozas-Kerstjens, Chao Zhang +6
Networks composed of independent sources of entangled particles that connect distant users are a rapidly developing quantum technology and an increasingly promising test-bed for fu…
Quantum Reference Frames for Lorentz Symmetry
Luca Apadula, Esteban Castro-Ruiz, Časlav Brukner
Since their first introduction, Quantum Reference Frame (QRF) transformations have been extensively discussed, generalising the covariance of physical laws to the quantum domain. D…
Lower Bounding Ground-State Energies of Local Hamiltonians Through the Renormalization Group
Ilya Kull, Norbert Schuch, Ben Dive +1
Given a renormalization scheme, we show how to formulate a tractable convex relaxation of the set of feasible local density matrices of a many-body quantum system. The relaxation i…
Variational theory of angulons and their rotational spectroscopy
Zhongda Zeng, Enderalp Yakaboylu, Mikhail Lemeshko +2
The angulon, a quasiparticle formed by a quantum rotor dressed by the excitations of a many-body bath, can be used to describe an impurity rotating in a fluid or solid environment.…
Indefinite causal order and quantum coordinates
Anne-Catherine de la Hamette, Viktoria Kabel, Marios Christodoulou +1
Classically the causal order of two timelike separated events A and B is fixed -- either A before B or B before A. This is no longer true in quantum theory, where it is possible to…
Characterizing entanglement dimensionality from randomized measurements
Shuheng Liu, Qiongyi He, Marcus Huber +2
We consider the problem of detecting the dimensionality of entanglement with the use of correlations between measurements in randomized directions. First, exploiting the recently d…
