Work and entropy production in generalised Gibbs ensembles
M. Perarnau-Llobet, A. Riera, R. Gallego +2
Recent years have seen an enormously revived interest in the study of thermodynamic notions in the quantum regime. This applies both to the study of notions of work extraction in t…
Adiabatic electronic flux density: a Born-Oppenheimer Broken Symmetry ansatz
Vincent Pohl, Jean Christophe Tremblay
The Born-Oppenheimer approximation leads to the counterintuitive result of a vanishing electronic flux density upon vibrational dynamics in the electronic ground state. To circumve…
Contextuality and Wigner function negativity in qubit quantum computation
Robert Raussendorf, Dan E. Browne, Nicolas Delfosse +2
We describe a scheme of quantum computation with magic states on qubits for which contextuality is a necessary resource possessed by the magic states. More generally, we establish…
Genuine quantum coherence
Julio I. de Vicente, Alexander Streltsov
Any quantum resource theory is based on free states and free operations, i.e., states and operations which can be created and performed at no cost. In the resource theory of cohere…
Cellular automaton decoders of topological quantum memories in the fault tolerant setting
M. Herold, M. J. Kastoryano, E. T. Campbell +1
Active error decoding and correction of topological quantum codes - in particular the toric code - remains one of the most viable routes to large scale quantum information processi…
An exponential time upper bound for Quantum Merlin-Arthur games with unentangled provers
Martin Schwarz
We prove a deterministic exponential time upper bound for Quantum Merlin-Arthur games with k unentangled provers. This is the first non-trivial upper bound of QMA(k) better than NE…
Towards resource theory of coherence in distributed scenarios
Alexander Streltsov, Swapan Rana, Manabendra Nath Bera +1
The search for a simple description of fundamental physical processes is an important part of quantum theory. One example for such an abstraction can be found in the distance lab p…
Weak values are quantum: you can bet on it
Alessandro Romito, Andrew N. Jordan, Yakir Aharonov +1
The outcome of a weak quantum measurement conditioned to a subsequent postselection (a weak value protocol) can assume peculiar values. These results cannot be explained in terms o…
Thermodynamics of weakly measured quantum systems
Jose Joaquin Alonso, Eric Lutz, Alessandro Romito
We consider continuously monitored quantum systems and introduce definitions of work and heat along individual quantum trajectories that are valid for coherent superpositions of en…
Characterizing and Quantifying Quantum Chaos with Quantum Tomography
Vaibhav Madhok, Carlos A. Riofrío, Ivan H. Deutsch
We explore quantum signatures of classical chaos by studying the rate of information gain in quantum tomography. The tomographic record consists of a time series of expectation val…
The maximum efficiency of nano heat engines depends on more than temperature
Mischa P. Woods, Nelly Ng, Stephanie Wehner
Sadi Carnot's theorem regarding the maximum efficiency of heat engines is considered to be of fundamental importance in thermodynamics. This theorem famously states that the maximu…
Advances in Quantum Teleportation
Stefano Pirandola, Jens Eisert, Christian Weedbrook +2
Quantum teleportation is one of the most important protocols in quantum information. By exploiting the physical resource of entanglement, quantum teleportation serves as a key prim…
Continuous matrix product state tomography of quantum transport experiments
G. Haack, A. Steffens, J. Eisert +1
In recent years, a close connection between the description of open quantum systems, the input-output formalism of quantum optics, and continuous matrix product states in quantum f…
Thermodynamic work from operational principles
R. Gallego, J. Eisert, H. Wilming
In recent years we have witnessed a concentrated effort to make sense of thermodynamics for small-scale systems. One of the main difficulties is to capture a suitable notion of wor…
Fermionic orbital optimisation in tensor network states
C. Krumnow, L. Veis, Ö. Legeza +1
Tensor network states and specifically matrix-product states have proven to be a powerful tool for simulating ground states of strongly correlated spin models. Recently, they have…
Renormalising entanglement distillation
Stephan Waeldchen, Janina Gertis, Earl T. Campbell +1
Entanglement distillation refers to the task of transforming a collection of weakly entangled pairs into fewer highly entangled ones. It is a core ingredient in quantum repeater pr…
Equilibration, thermalisation, and the emergence of statistical mechanics in closed quantum systems
C. Gogolin, J. Eisert
We review selected advances in the theoretical understanding of complex quantum many-body systems with regard to emergent notions of quantum statistical mechanics. We cover topics…
Resilience of hybrid optical angular momentum qubits to turbulence
Osvaldo Jiménez Farías, Vincenzo D'Ambrosio, Caterina Taballione +6
Recent schemes to encode quantum information into the total angular momentum of light, defining rotation-invariant hybrid qubits composed of the polarization and orbital angular mo…
Decoherence in open Majorana systems
Earl T. Campbell
Coupling to a thermal bath leads to decoherence of stored quantum information. For a system of Gaussian fermions, the fermionic analog of linear or Gaussian optics, these dynamics…
Bulk-edge correspondence of one-dimensional quantum walks
C. Cedzich, F. A. Grünbaum, C. Stahl +3
We outline a theory of symmetry protected topological phases of one-dimensional quantum walks. We assume spectral gaps around the symmetry-distinguished points +1 and -1, in which…
