Device-independent Certification of One-shot Distillable Entanglement
Rotem Arnon, Jean-Daniel Bancal
Entanglement sources that produce many entangled states act as a main component in applications exploiting quantum physics such as quantum communication and cryptography. Realistic…
Efficient Extraction of Light from a Nitrogen-Vacancy Center in a Diamond Parabolic Reflector
Noel H. Wan, Brendan J. Shields, Donggyu Kim +6
Quantum emitters in solids are being developed for a range of quantum technologies, including quantum networks, computing, and sensing. However, a remaining challenge is the poor p…
Quantum optics with near lifetime-limited quantum-dot transitions in a nanophotonic waveguide
Henri Thyrrestrup, Gabija Kiršanskė, Hanna Le Jeannic +13
Establishing a highly efficient photon-emitter interface where the intrinsic linewidth broadening is limited solely by spontaneous emission is a key step in quantum optics. It open…
Simple proof of confidentiality for private quantum channels in noisy environments
A. Pirker, M. Zwerger, V. Dunjko +2
Complete security proofs for quantum communication protocols can be notoriously involved, which convolutes their verification, and obfuscates the key physical insights the security…
On-demand semiconductor source of 780 nm single photons with controlled temporal wave packets
Lucas Béguin, Jan-Philipp Jahn, Janik Wolters +8
We report on a fast, bandwidth-tunable single-photon source based on an epitaxial GaAs quantum dot. Exploiting spontaneous spin-flip Raman transitions, single photons at nm…
High-detection efficiency and low-timing jitter with amorphous superconducting nanowire single-photon detectors
Misael Caloz, Matthieu Perrenoud, Claire Autebert +6
Recent progress in the development of superconducting nanowire single-photon detectors (SNSPDs) made of amorphous material has delivered excellent performances, and has had a great…
Spin-photon interface and spin-controlled photon switching in a nanobeam waveguide
Alisa Javadi, Dapeng Ding, Martin Hayhurst Appel +13
Access to the electron spin is at the heart of many protocols for integrated and distributed quantum-information processing [1-4]. For instance, interfacing the spin-state of an el…
Quantum and classical dynamics of a three-mode absorption refrigerator
Stefan Nimmrichter, Jibo Dai, Alexandre Roulet +1
We study the quantum and classical evolution of a system of three harmonic modes interacting via a trilinear Hamiltonian. With the modes prepared in thermal states of different tem…
A repetition code of 15 qubits
James R. Wootton, Daniel Loss
The repetition code is an important primitive for the techniques of quantum error correction. Here we implement repetition codes of at most qubits on the qubit \emph{ibmq…
Quantum probe hyperpolarisation of molecular nuclear spins
David A. Broadway, Jean-Philippe Tetienne, Alastair Stacey +4
The hyperpolarisation of nuclear spins within target molecules is a critical and complex challenge in magnetic resonance imaging (MRI) and nuclear magnetic resonance (NMR) spectros…
Many-box locality
Yuqian Zhou, Yu Cai, Jean-Daniel Bancal +2
There is an ongoing search for a physical or operational definition for quantum mechanics. Several informational principles have been proposed which are satisfied by a theory less…
Spatial entanglement patterns and Einstein-Podolsky-Rosen steering in a Bose-Einstein condensate
Matteo Fadel, Tilman Zibold, Boris Décamps +1
Many-particle entanglement is a fundamental concept of quantum physics that still presents conceptual challenges. While spin-squeezed and other nonclassical states of atomic ensemb…
