A gated quantum dot far in the strong-coupling regime of cavity-QED at optical frequencies
Daniel Najer, Immo Söllner, Pavel Sekatski +10
The strong-coupling regime of cavity-quantum-electrodynamics (cQED) represents light-matter interaction at the fully quantum level. Adding a single photon shifts the resonance freq…
Optimal synchronization deep in the quantum regime: resource and fundamental limit
Martin Koppenhöfer, Alexandre Roulet
We develop an analytical framework to study the synchronization of a quantum self-sustained oscillator to an external signal. Our unified description allows us to identify the reso…
Self-testing with finite statistics enabling the certification of a quantum network link
Jean-Daniel Bancal, Kai Redeker, Pavel Sekatski +2
Self-testing is a method to certify devices from the result of a Bell test. Although examples of noise tolerant self-testing are known, it is not clear how to deal efficiently with…
Device-independent characterization of quantum instruments
Sebastian Wagner, Jean-Daniel Bancal, Nicolas Sangouard +1
Among certification techniques, those based on the violation of Bell inequalities are appealing because they do not require assumptions on the underlying Hilbert space dimension an…
Nonlinear Quantum Behavior of Ultrashort-Pulse Optical Parametric Oscillators
Tatsuhiro Onodera, Edwin Ng, Chris Gustin +6
The quantum features of ultrashort-pulse optical parametric oscillators (OPOs) are investigated theoretically in the nonlinear regime near and above threshold. Viewing the pulsed O…
Universal quantum computation in the surface code using non-Abelian islands
Katharina Laubscher, Daniel Loss, James R. Wootton
The surface code is currently the primary proposed method for performing quantum error correction. However, despite its many advantages, it has no native method to fault-tolerantly…
Efficiently measuring a quantum device using machine learning
D. T. Lennon, H. Moon, L. C. Camenzind +6
Scalable quantum technologies will present challenges for characterizing and tuning quantum devices. This is a time-consuming activity, and as the size of quantum systems increases…
Bipartite nonlocality with a many-body system
Enky Oudot, Jean-Daniel Bancal, Pavel Sekatski +1
We consider a bipartite scenario where two parties hold ensembles of -spins which can only be measured collectively. We give numerical arguments supporting the conjecture that…
Coherent optical control of a quantum-dot spin-qubit in a waveguide-based spin-photon interface
Dapeng Ding, Martin Hayhurst Appel, Alisa Javadi +12
Waveguide-based spin-photon interfaces on the GaAs platform have emerged as a promising system for a variety of quantum information applications directly integrated into planar pho…
Radio-frequency reflectometry of a quantum dot using an ultra-low-noise SQUID amplifier
F. J. Schupp, F. Vigneau, Y. Wen +12
Fault-tolerant spin-based quantum computers will require fast and accurate qubit readout. This can be achieved using radio-frequency reflectometry given sufficient sensitivity to t…
Does a large quantum Fisher information imply Bell correlations?
Florian Fröwis, Matteo Fadel, Philipp Treutlein +2
The quantum Fisher information (QFI) of certain multipartite entangled quantum states is larger than what is reachable by separable states, providing a metrological advantage. Are…
Revealing the work cost of generalized thermal baths
Alexandre Roulet
We derive the work cost of using generalized thermal baths from the physical equivalence of quantum mechanics under unitary transformations. We demonstrate our method by considerin…
Device-independent detection of genuine multipartite entanglement for all pure states
M. Zwerger, W. Dür, J. -D. Bancal +1
We show that genuine multipartite entanglement of all multipartite pure states in arbitrary finite dimension can be detected in a device-independent way by employing bipartite Bell…
Split spin-squeezed Bose-Einstein Condensates
Yumang Jing, Matteo Fadel, Valentin Ivannikov +1
We investigate and model the behaviour of split spin-squeezed Bose-Einstein condensates (BECs) system. In such a system, a spin-polarized BEC is first squeezed using a …
Benchmarks for approximate CNOTs based on a 17-Qubit Surface Code
Andreas Peter, Daniel Loss, James R. Wootton
Scalable and fault-tolerant quantum computation will require error correction. This will demand constant measurement of many-qubit observables, implemented using a vast number of C…
Noise-resistant device-independent certification of Bell state measurements
Jean-Daniel Bancal, Nicolas Sangouard, Pavel Sekatski
Device-independent certification refers to the characterization of an apparatus without reference to the internal description of other devices. It is a trustworthy certification me…
Photon Recoil Spectroscopy: Systematic Shifts and Nonclassical Enhancements
Marius Schulte, Niels Lörch, Piet O. Schmidt +1
In photon recoil spectroscopy, signals are extracted from recoils imparted by the spectroscopy light on the motion of trapped ions as demonstrated by C. Hempel et al., Nature Photo…
Unraveling nonclassicality in the optomechanical instability
Martin Koppenhöfer, Christoph Bruder, Niels Lörch
Conditional dynamics due to continuous optical measurements has successfully been applied for state reconstruction and feedback cooling in optomechanical systems. In this article,…
Quantum synchronization and entanglement generation
Alexandre Roulet, Christoph Bruder
We study synchronization in a two-node network built out of the smallest possible self-sustained oscillator: a spin 1. We first demonstrate that phase locking between the quantum o…
Randomness extraction from Bell violation with continuous parametric down conversion
Lijiong Shen, Jianwei Lee, Le Phuc Thinh +8
We present a violation of the CHSH inequality without the fair sampling assumption with a continuously pumped photon pair source combined with two high efficiency superconducting d…
All macroscopic quantum states are fragile and hard to prepare
Andrea López-Incera, Pavel Sekatski, Wolfgang Dür
We study the effect of local decoherence on arbitrary quantum states. Adapting techniques developed in quantum metrology, we show that the action of generic local noise processes -…
