Catalysis and activation of magic states in fault tolerant architectures
Earl T. Campbell
In many architectures for fault tolerant quantum computing universality is achieved by a combination of Clifford group unitary operators and preparation of suitable nonstabilizer s…
Non-adaptive Measurement-based Quantum Computation and Multi-party Bell Inequalities
Matty J. Hoban, Earl T. Campbell, Klearchos Loukopoulos +1
Quantum correlations exhibit behaviour that cannot be resolved with a local hidden variable picture of the world. In quantum information, they are also used as resources for inform…
Absence of Thermalization in Nonintegrable Systems
Christian Gogolin, Markus P. Mueller, Jens Eisert
We establish a link between unitary relaxation dynamics after a quench in closed many-body systems and the entanglement in the energy eigenbasis. We find that even if reduced state…
Directly estimating non-classicality
A. Mari, K. Kieling, B. Melholt Nielsen +2
We establish a method of directly measuring and estimating non-classicality - operationally defined in terms of the distinguishability of a given state from one with a positive Wig…
Temperature dependence of the plasmonic Casimir interaction
F. Intravaia, H. Haakh, C. Henkel
We investigate the role of surface plasmons in the electromagnetic Casimir effect at finite temperature, including situations out of global thermal equilibrium. The free energy is…
A derivation of quantum theory from physical requirements
Lluis Masanes, Markus P. Mueller
Quantum theory is usually formulated in terms of abstract mathematical postulates, involving Hilbert spaces, state vectors, and unitary operators. In this work, we show that the fu…
