Efficient Decoders for Qudit Topological Codes
Hussain Anwar, Benjamin J. Brown, Earl T. Campbell +1
Qudit toric codes are a natural higher-dimensional generalization of the well-studied qubit toric code. However standard methods for error correction of the qubit toric code are no…
Detecting nonlocality of noisy multipartite states with the CHSH inequality
Rafael Chaves, Antonio Acín, Leandro Aolita +1
The Clauser-Horne-Shimony-Holt inequality was originally proposed as a Bell inequality to detect nonlocality in bipartite systems. However, it can also be used to certify the nonlo…
Topological insulators with arbitrarily tunable entanglement
J. C. Budich, J. Eisert, E. J. Bergholtz
We elucidate how Chern and topological insulators fulfill an area law for the entanglement entropy. By explicit construction of a family of lattice Hamiltonians, we are able to dem…
Thermal machines beyond the weak coupling regime
R. Gallego, A. Riera, J. Eisert
How much work can be extracted from a heat bath using a thermal machine? The study of this question has a very long tradition in statistical physics in the weak-coupling limit, app…
Breakdown of quasilocality in long-range quantum lattice models
J. Eisert, M. van den Worm, S. R. Manmana +1
We study the non-equilibrium dynamics of correlations in quantum lattice models in the presence of long-range interactions decaying asymptotically as a power law. For exponents lar…
Locality of temperature
M. Kliesch, C. Gogolin, M. J. Kastoryano +2
This work is concerned with thermal quantum states of Hamiltonians on spin and fermionic lattice systems with short range interactions. We provide results leading to a local defini…
Bohm Trajectories as Approximations to Properly Fluctuating Quantum Trajectories
Pisin Chen, Hagen Kleinert
We explain the approximate nature of particle trajectories in Bohm's quantum mechanics. They are streamlines of a superfluid in Madelung's reformulation of the Schrödinger wave fun…
Nonlocality in sequential correlation scenarios
Rodrigo Gallego, Lars Erik Würflinger, Rafael Chaves +2
As first shown by Popescu [S. Popescu, Phys. Rev. Lett. 74, 2619 (1995)], some quantum states only reveal their nonlocality when subjected to a sequence of measurements while givin…
Lieb-Robinson bounds for spin-boson lattice models and trapped ions
J. Juenemann, A. Cadarso, D. Perez-Garcia +2
We derive a Lieb-Robinson bound for the propagation of spin correlations in a model of spins interacting through a bosonic lattice field, which satisfies itself a Lieb-Robinson bou…
Boson-Sampling in the light of sample complexity
C. Gogolin, M. Kliesch, L. Aolita +1
Boson-Sampling is a classically computationally hard problem that can - in principle - be efficiently solved with quantum linear optical networks. Very recently, a rush of experime…
Photonic polarization gears for ultra-sensitive angular measurements
V. D'Ambrosio, N. Spagnolo, L. Del Re +7
Quantum metrology bears a great promise in enhancing measurement precision, but is unlikely to become practical in the near future. Its concepts can nevertheless inspire classical…
Lieb-Robinson bounds and the simulation of time evolution of local observables in lattice systems
Martin Kliesch, Christian Gogolin, Jens Eisert
This is an introductory text reviewing Lieb-Robinson bounds for open and closed quantum many-body systems. We introduce the Heisenberg picture for time-dependent local Liouvillians…
Observation of non-Markovian micro-mechanical Brownian motion
S. Groeblacher, A. Trubarov, N. Prigge +3
All physical systems are to some extent open and interacting with their environment. This insight, basic as it may seem, gives rise to the necessity of protecting quantum systems f…
Majorana fermions and non-locality
Earl T. Campbell, Matty J. Hoban, Jens Eisert
Localized Majorana fermions emerge in many topologically ordered systems and exhibit exchange statistics of Ising anyons. This enables noise-resistant implementation of a limited s…
Standard and Null Weak Values
Oded Zilberberg, Alessandro Romito, Yuval Gefen
Weak value (WV) is a quantum mechanical measurement protocol, proposed by Aharonov, Albert, and Vaidman. It consists of a weak measurement, which is weighed in, conditional on the…
Rapid mixing implies exponential decay of correlations
Michael J. Kastoryano, Jens Eisert
We provide an analysis of the correlation properties of spin and fermionic systems on a lattice evolving according to open system dynamics generated by a local primitive Liouvillia…
Quantum speed limit for non-Markovian dynamics
Sebastian Deffner, Eric Lutz
We derive a Margolus-Levitin type bound on the minimal evolution time of an arbitrarily driven open quantum system. We express this quantum speed limit time in terms of the operato…
Propagation and spectral properties of quantum walks in electric fields
C. Cedzich, T. Rybár, A. H. Werner +3
We study one-dimensional quantum walks in a homogeneous electric field. The field is given by a phase which depends linearly on position and is applied after each step. The long ti…
Information gain in tomography - A quantum signature of chaos
Vaibhav Madhok, Carlos A. Riofrío, Shohini Ghose +1
We find quantum signatures of classical chaos in various metrics of information gain in quantum tomography. We employ a quantum state estimator based on weak collective measurement…
Robust amplification of Santha-Vazirani sources with three devices
Piotr Mironowicz, Rodrigo Gallego, Marcin Pawlowski
We demonstrate that amplification of arbitrarily weak randomness is possible using quantum resources. We present a randomness amplification protocol that involves Bell experiments.…
Mutual information area laws for thermal free fermions
H. Bernigau, M. J. Kastoryano, J. Eisert
We provide a rigorous and asymptotically exact expression of the mutual information of translationally invariant free fermionic lattice systems in a Gibbs state. In order to arrive…
