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…
CHSH Bell Tests For Optical Hybrid Entanglement
Morteza Moradi, Juan Camilo López Carreño, Adam Buraczewski +4
Optical hybrid entanglement can be created between two qubits, one encoded in a single photon and another one in coherent states with opposite phases. It opens the path to a variet…
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…
Adapting coherent-state superpositions in noisy channels
Jan Provazník, Petr Marek, Julien Laurat +1
Quantum non-Gaussian states are crucial for the fundamental understanding of non-linear bosonic systems and simultaneously advanced applications in quantum technologies. In many bo…
Slowing Quantum Decoherence by Squeezing in Phase Space
H. Le Jeannic, A. Cavaillès, K. Huang +2
Non-Gaussian states, and specifically the paradigmatic Schrödinger cat state, are well-known to be very sensitive to losses. When propagating through damping channels, these states…
Witnessing trustworthy single-photon entanglement with local homodyne measurements
Olivier Morin, Jean-Daniel Bancal, Melvyn Ho +5
Single-photon entangled states, i.e. states describing two optical paths sharing a single photon, constitute the simplest form of entanglement. Yet they provide a valuable resource…
