Shorter unentangled proofs for Ground State Connectivity
Libor Caha, Daniel Nagaj, Martin Schwarz
Can one considerably shorten a proof for a quantum problem by using a protocol with a constant number of unentangled provers? We consider a frustration-free variant of the QCMA-com…
The European Quantum Technologies Roadmap
Antonio Acín, Immanuel Bloch, Harry Buhrman +15
Within the last two decades, Quantum Technologies (QT) have made tremendous progress, moving from Noble Prize award-winning experiments on quantum physics into a cross-disciplinary…
Experimental Demonstration of Quantum Tunneling in IBM Quantum Computer
Narendra N. Hegade, Nachiket L. Kortikar, Bikramaditya Das +2
Quantum computers are the promising candidates for simulation of large quantum systems, which is a daunting task to perform in a classical computer. Here, we report the experimenta…
What it takes to shun equilibration
R. Gallego, H. Wilming, J. Eisert +1
Numerous works have shown that under mild assumptions unitary dynamics inevitably leads to equilibration of physical expectation values if many energy eigenstates contribute to the…
Rates of multi-partite entanglement transformations and applications in quantum networks
A. Streltsov, C. Meignant, J. Eisert
The theory of the asymptotic manipulation of pure bipartite quantum systems can be considered completely understood: The rates at which bipartite entangled states can be asymptotic…
Lattice Surgery with a Twist: Simplifying Clifford Gates of Surface Codes
Daniel Litinski, Felix von Oppen
We present a planar surface-code-based scheme for fault-tolerant quantum computation which eliminates the time overhead of single-qubit Clifford gates, and implements long-range mu…
A fermionic de Finetti theorem
C. Krumnow, Z. Zimboras, J. Eisert
Quantum versions of de Finetti's theorem are powerful tools, yielding conceptually important insights into the security of key distribution protocols or tomography schemes and allo…
Statistical ensembles without typicality
Paul Boes, Henrik Wilming, Jens Eisert +1
Maximum-entropy ensembles are key primitives in statistical mechanics from which thermodynamic properties can be derived. Over the decades, several approaches have been put forward…
WavePacket: A Matlab package for numerical quantum dynamics. II: Open quantum systems, optimal control, and model reduction
Burkhard Schmidt, Carsten Hartmann
WavePacket is an open-source program package for numeric simulations in quantum dynamics. It can solve time-independent or time-dependent linear Schrödinger and Liouville-von Neuma…
Anticoncentration theorems for schemes showing a quantum speedup
Dominik Hangleiter, Juan Bermejo-Vega, Martin Schwarz +1
One of the main milestones in quantum information science is to realise quantum devices that exhibit an exponential computational advantage over classical ones without being univer…
Universal extensions of restricted classes of quantum operations
Michał Oszmaniec, Zoltán Zimborás
For numerous applications of quantum theory it is desirable to be able to apply arbitrary unitary operations on a given quantum system. However, in particular situations only a sub…
Structure of the resource theory of quantum coherence
Alexander Streltsov, Swapan Rana, Paul Boes +1
Quantum coherence is an essential feature of quantum mechanics which is responsible for the departure between classical and quantum world. The recently established resource theory…
Towards local equilibration in closed interacting quantum many-body systems
H. Wilming, M. Goihl, C. Krumnow +1
One of the main questions of research on quantum many-body systems following unitary out of equilibrium dynamics is to find out how local expectation values equilibrate in time. Fo…
Strong coupling corrections in quantum thermodynamics
M. Perarnau-Llobet, H. Wilming, A. Riera +2
Quantum systems strongly coupled to many-body systems equilibrate to the reduced state of a global thermal state, deviating from the local thermal state of the system as it occurs…
Conditional quasi-exact solvability of the quantum planar pendulum and of its anti-isospectral hyperbolic counterpart
Simon Becker, Marjan Mirahmadi, Burkhard Schmidt +2
We have subjected the planar pendulum eigenproblem to a symmetry analysis with the goal of explaining the relationship between its conditional quasi-exact solvability (C-QES) and t…
Precision bounds for gradient magnetometry with atomic ensembles
Iagoba Apellaniz, Inigo Urizar-Lanz, Zoltan Zimboras +2
We study gradient magnetometry with an ensemble of atoms with arbitrary spin. We calculate precision bounds for estimating the gradient of the magnetic field based on the quantum F…
Finite-time quantum entanglement in propagating squeezed microwaves
Kirill G. Fedorov, S. Pogorzalek, U. Las Heras +13
Two-mode squeezing is a fascinating example of quantum entanglement manifested in cross-correlations of incompatible observables between two subsystems. At the same time, these sub…

One of the main aims in the field of quantum simulation is to achieve a quantum speedup, often referred to as "quantum computational supremacy", referring to the experimental reali…
Third Law of Thermodynamics as a Single Inequality
Henrik Wilming, Rodrigo Gallego
The third law of thermodynamics in the form of the unattainability principle states that exact ground-state cooling requires infinite resources. Here we investigate the amount of n…
Guaranteed recovery of quantum processes from few measurements
Martin Kliesch, Richard Kueng, Jens Eisert +1
Quantum process tomography is the task of reconstructing unknown quantum channels from measured data. In this work, we introduce compressed sensing-based methods that facilitate th…
