Ultralow-power single-pass all-optical photon router
Jérémy Berroir, Tridib Ray, Alban Urvoy +1
We demonstrate a novel approach for routing guided single photons by combining atom trapping and transverse light confinement with an optical nanofiber. The direction of photon pro…
Hierarchies of quantum non-Gaussian coherences for bosonic systems: A theoretical study
Lukáš Lachman, Beate E. Asenbeck, Ambroise Boyer +4
Quantum coherence in bosonic systems is a fundamental resource for quantum technology applications. In this work, we introduce a framework for analyzing coherence in the Fock-state…
Hierarchical Verification of Non-Gaussian Coherence in Bosonic Quantum States
Beate E. Asenbeck, Lukáš Lachman, Ambroise Boyer +4
Non-Gaussianity, a distinctive characteristic of bosonic quantum states, is pivotal in advancing quantum networks, fault-tolerant quantum computing, and high-precision metrology. V…
Quantum cryptography integrating an optical quantum memory
H. Mamann, T. Nieddu, F. Hoffet +6
Developments in scalable quantum networks rely critically on optical quantum memories, which are key components enabling the storage of quantum information. These memories play a p…
A Hybrid Approach to Mitigate Errors in Linear Photonic Bell-State Measurement for Quantum Interconnects
Beate E. Asenbeck, Akito Kawasaki, Ambroise Boyer +4
Optical quantum information processing critically relies on Bell-state measurement, a ubiquitous operation for quantum communication and computing. Its practical realization involv…
