Superconducting grid-bus surface code architecture for hole-spin qubits
Simon E. Nigg, Andreas Fuhrer, Daniel Loss
We present a scalable hybrid architecture for the 2D surface code combining superconducting resonators and hole-spin qubits in nanowires with tunable direct Rashba spin-orbit coupl…
Proposal for witnessing non-classical light with the human eye
A. Dodel, A. Mayinda, E. Oudot +4
We give a complete proposal showing how to detect the non-classical nature of photonic states with naked eyes as detectors. The enabling technology is a sub-Poissonian photonic sta…
Quantum repeaters based on trapped ions with decoherence free subspace encoding
M. Zwerger, B. P. Lanyon, T. E. Northup +3
Quantum repeaters provide an efficient solution to distribute Bell pairs over arbitrarily long distances. While scalable architectures are demanding regarding the number of qubits…
Witnessing irreducible dimension
Wan Cong, Yu Cai, Jean-Daniel Bancal +1
The Hilbert space dimension of a quantum system is the most basic quantifier of its information content. Lower bounds on the dimension can be certified in a device-independent way,…
Robust quantum optimizer with full connectivity
Simon E. Nigg, Niels Loerch, Rakesh P. Tiwari
Quantum phenomena have the potential to speed up the solution of hard optimization problems. For example quantum annealing, based on the quantum tunneling effect, has recently been…
Demonstrating non-Abelian braiding of surface code defects in a five qubit experiment
James R. Wootton
Currently, the mainstream approach to quantum computing is through surface codes. One way to store and manipulate quantum information with these to create defects in the codes whic…
Poking holes and cutting corners to achieve Clifford gates with the surface code
Benjamin J. Brown, Katharina Laubscher, Markus S. Kesselring +1
The surface code is currently the leading proposal to achieve fault-tolerant quantum computation. Among its strengths are the plethora of known ways in which fault-tolerant Cliffor…
Quantum metrology with nonclassical states of atomic ensembles
Luca Pezzè, Augusto Smerzi, Markus K. Oberthaler +2
Quantum technologies exploit entanglement to revolutionize computing, measurements, and communications. This has stimulated the research in different areas of physics to engineer a…
Resonant driving of a single photon emitter embedded in a mechanical oscillator
Mathieu Munsch, Andreas V. Kuhlmann, Davide Cadeddu +4
Coupling a microscopic mechanical resonator to a nano-scale quantum system enables control of the mechanical resonator via the quantum system, and vice versa. The coupling is usual…
A proposal for a minimal surface code experiment
James R. Wootton, Andreas Peter, Janos R. Winkler +1
Current quantum technology is approaching the system sizes and fidelities required for quantum error correction. It is therefore important to determine exactly what is needed for p…
Implementing and characterizing precise multi-qubit measurements
J. Z. Blumoff, K. Chou, C. Shen +12
There are two general requirements to harness the computational power of quantum mechanics: the ability to manipulate the evolution of an isolated system and the ability to faithfu…
Optomechanical Self-Oscillations in an Anharmonic Potential: Engineering a Nonclassical Steady State
Manuel Grimm, Christoph Bruder, Niels Lörch
We study self-oscillations of an optomechanical system, where coherent mechanical oscillations are induced by a driven optical or microwave cavity, for the case of an anharmonic me…
Bounding quantum gravity inspired decoherence using atom interferometry
Jiří Minář, Pavel Sekatski, Nicolas Sangouard
Hypothetical models have been proposed in which explicit collapse mechanisms prevent the superposition principle to hold at large scales. In particular, the model introduced by Ell…
Bell Correlations in a Bose-Einstein Condensate
Roman Schmied, Jean-Daniel Bancal, Baptiste Allard +4
Characterizing many-body systems through the quantum correlations between their constituent particles is a major goal of quantum physics. Although entanglement is routinely observe…
Two dimensional quantum repeaters
J. Wallnöfer, M. Zwerger, C. Muschik +2
The endeavour to develop quantum networks gave rise to a rapidly developing field with far reaching applications such as secure communication and the realisation of distributed com…
Sideband Rabi spectroscopy of finite-temperature trapped Bose gases
Baptiste Allard, Matteo Fadel, Roman Schmied +1
We use Rabi spectroscopy to explore the low-energy excitation spectrum of a finite-temperature Bose gas of rubidium atoms across the phase transition to a Bose-Einstein condensate…
Genuine quantum signatures in synchronization of anharmonic self-oscillators
Niels Lörch, Ehud Amitai, Andreas Nunnenkamp +1
We study the synchronization of a van der Pol self-oscillator with Kerr anharmonicity to an external drive. We demonstrate that the anharmonic, discrete energy spectrum of the quan…
Generation of spin-dependent coherent states in a quantum wire
J. Pawłowski, P. Szumniak, S. Bednarek
We propose an all-electrically controlled nanodevice - a gated semiconductor nanowire - capable of generating a coherent state of a single electron trapped in a harmonic oscillator…
Generation of single photons with highly tunable wave shape from a cold atomic quantum memory
Pau Farrera, Georg Heinze, Boris Albrecht +5
We report on a single photon source with highly tunable photon shape based on a cold ensemble of Rubidium atoms. We follow the DLCZ scheme to implement an emissive quantum memory,…
