Environment-Assisted Decoherence Suppression of Optical Non-Gaussian States
Akihiro Machinaga, Naoki Aritomi, Ryoga Sakurada +10
Optical loss is a common bottleneck in photonic quantum information processing, undermining the quantum advantage over classical approaches. Although several countermeasures, such…
Deterministic feedforward-based generation of large optical coherent-state superposition
Michele N. Notarnicola, Marcin Jarzyna, Radim Filip
Large optical coherent-state superpositions are essential to advance quantum sensing, quantum repeaters and error-correction codes. We propose a deterministic feedforward protocol…
Nonlocal continuous-variable gates by amplified optical connections
Michele N. Notarnicola, Radim Filip
Nonlocal quantum gates, coupling quantum systems located at a distance, are crucial for distributed quantum computing. To this aim, high-capacity optical noiseless connections betw…
Cavity-QED tools for MBQC with optical binomial-codes
G. P. Teja, Radim Filip
Measurement-based quantum computation (MBQC) offers a promising paradigm for photonic quantum computing, but its implementation requires the generation of specific non-Gaussian res…
Coherence of quantum non-Gaussian states via nonlinear absorption of quanta
Kingshuk Adhikary, Darren W. Moore, Radim Filip
The linear and phase insensitive absorption of a single quanta via coherent interactions with a saturable system, even a single ground state qubit, is sufficient to deterministical…
Local quantum coherence with intersource interactions at nonzero temperature
Yehor Hudenko, Michal Kolář, Radim Filip +1
Local quantum coherence in a two-level system (TLS) is typically generated via time-dependent driving. However, it can also emerge autonomously from symmetry-breaking interactions…
Quantum non-Gaussian high Fock states of light pulses and their superpositions
G. P. Teja, Chandan Kumar, Lukáš Lachman +1
The generation of high Fock states of light pulses and their superpositions with provable quantum non-Gaussian features is still very challenging, although the power of conditional…
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 non-Gaussian coherences of an oscillating atom
A. Kovalenko, L. Lachman, T. Pham +4
Quantum coherence between energy eigenstates of harmonic oscillators is essential for quantum physics. Even the most elementary binary superpositions of the ground and the higher e…
Genuine quantum non-Gaussianity and metrological sensitivity of Fock states prepared in a mechanical resonator
Q. Rumman Rahman, Igor Kladarić, Max-Emanuel Kern +4
Fock states of the quantum harmonic oscillator are fundamental to quantum sensing and information processing, serving as key resources for exploiting bosonic degrees of freedom. He…
