Quantum simulation of open-system dynamical maps with trapped ions
P. Schindler, M. Müller, D. Nigg +7
Dynamical maps describe general transformations of the state of a physical system, and their iteration can be interpreted as generating a discrete time evolution. Prime examples in…
Experimental Boson Sampling
Max Tillmann, Borivoje Dakić, René Heilmann +3
Universal quantum computers promise a dramatic speed-up over classical computers but a full-size realization remains challenging. However, intermediate quantum computational models…
Real-Time Imaging of Quantum Entanglement
Robert Fickler, Mario Krenn, Radek Lapkiewicz +2
Quantum Entanglement is widely regarded as one of the most prominent features of quantum mechanics and quantum information science. Although, photonic entanglement is routinely stu…
Highly efficient heralding of entangled single photons
Sven Ramelow, Alexandra Mech, Marissa Giustina +8
Single photons are an important prerequisite for a broad spectrum of quantum optical applications. We experimentally demonstrate a heralded single-photon source based on spontaneou…
Quantum optics experiments to the International Space Station ISS: a proposal
Thomas Scheidl, Eric Wille, Rupert Ursin
We propose performing quantum optics experiments in an ground-to-space scenario using the International Space Station, which is equipped with a glass viewing window and a photograp…
Undoing a quantum measurement
Philipp Schindler, Thomas Monz, Daniel Nigg +6
In general, a quantum measurement yields an undetermined answer and alters the system to be consistent with the measurement result. This process maps multiple initial states into a…
Can different quantum state vectors correspond to the same physical state? An experimental test
Daniel Nigg, Thomas Monz, Philipp Schindler +7
A century on from the development of quantum theory, the interpretation of a quantum state is still discussed. If a physicist claims to have produced a system with a particular wav…
Deterministic generation of arbitrary symmetric states and entanglement classes
L. Lamata, C. E. Lopez, B. P. Lanyon +3
We propose a method to generate arbitrary symmetric states of N qubits, which can be easily associated with their entanglement classes. It is particularly suited to quantum optics…
A Classical Framework for Nonlocality and Entanglement
Gerhard Groessing, Siegfried Fussy, Johannes Mesa Pascasio +1
Based on our model of quantum systems as emerging from the coupled dynamics between oscillating "bouncers" and the space-filling zero-point field, a sub-quantum account of nonlocal…
Single-photon nonlinearities in two-mode optomechanics
P. Kómár, S. D. Bennett, K. Stannigel +4
We present a detailed theoretical analysis of a weakly driven multimode optomechanical system, in which two optical modes are strongly and near-resonantly coupled to a single mecha…
Experimental quantum teleportation over a high-loss free-space channel
Xiao-Song Ma, Sebastian Kropatschek, William Naylor +5
We present a high-fidelity quantum teleportation experiment over a high-loss free-space channel between two laboratories. We teleported six states of three mutually unbiased bases…
Real-Vector-Space Quantum Theory with a Universal Quantum Bit
Antoniya Aleksandrova, Victoria Borish, William K. Wootters
We explore a model of the world based on real-vector-space quantum theory. In our model the familiar complex phase appearing in quantum states is replaced by a single binary object…
Bound entanglement helps to reduce communication complexity
Michael Epping, Caslav Brukner
We present a simple communication complexity problem where three parties benefit from sharing bound entanglement. This demonstrates that entanglement distillability of the shared s…
Attacks on quantum key distribution protocols that employ non-ITS authentication
Christoph Pacher, Aysajan Abidin, Thomas Lorünser +4
We demonstrate how adversaries with unbounded computing resources can break Quantum Key Distribution (QKD) protocols which employ a particular message authentication code suggested…
Quantum control of spin-correlations in ultracold lattice gases
P. Hauke, R. J. Sewell, M. W. Mitchell +1
We demonstrate that it is possible to prepare a lattice gas of ultracold atoms with a desired non-classical spin-correlation function using atom-light interaction of the kind routi…
Parallel execution of quantum gates in a long linear ion chain via Rydberg mode shaping
Weibin Li, Alexander W. Glaetzle, Rejish Nath +1
We present a mechanism that permits the parallel execution of multiple quantum gate operations within a single long linear ion chain. Our approach is based on large coherent forces…
Impact of turbulence in long range quantum and classical communications
I. Capraro, A. Tomaello, A. Dall'Arche +4
The study of the free-space distribution of quantum correlations is necessary for any future application of quantum as classical communication aiming to connect two remote location…
Atom-atom entanglement by single-photon detection
L. Slodička, G. Hétet, N. Röck +3
A scheme for entangling distant atoms is realized, as proposed in the seminal paper by Cabrillo et al. [Phys. Rev. A 59, 1025 (1999)]. The protocol is based on quantum interference…
Condition for macroscopic realism beyond the Leggett-Garg inequalities
Johannes Kofler, Caslav Brukner
In 1985, Leggett and Garg put forward the concept of macroscopic realism (macrorealism) and, in analogy to Bell's theorem, derived a necessary condition in terms of inequalities, w…
Quantum Entanglement of High Angular Momenta
Robert Fickler, Radek Lapkiewicz, William N. Plick +4
Single photons with helical phase structures may carry a quantized amount of orbital angular momentum (OAM) and their entanglement is important for quantum information science and…
Hardware-efficient autonomous quantum error correction
Zaki Leghtas, Gerhard Kirchmair, Brian Vlastakis +3
We propose a new method to autonomously correct for errors of a logical qubit induced by energy relaxation. This scheme encodes the logical qubit as a multi-component superposition…
Nonlocal appearance of a macroscopic angular momentum
G. S. Paraoanu, R. Healey
We discuss a type of measurement in which a macroscopically large angular momentum (spin) is "created" nonlocally by the measurement of just a few atoms from a double Fock state. T…
Quantum erasure with causally disconnected choice
Xiao-song Ma, Johannes Kofler, Angie Qarry +9
The counterintuitive features of quantum physics challenge many common-sense assumptions. In an interferometric quantum eraser experiment, one can actively choose whether or not to…
Reservoir engineering and dynamical phase transitions in optomechanical arrays
A. Tomadin, S. Diehl, M. D. Lukin +2
We study the driven-dissipative dynamics of photons interacting with an array of micromechanical membranes in an optical cavity. Periodic membrane driving and phonon creation resul…
