Direct estimation of arbitrary observables of an oscillator
Tanjung Krisnanda, Fernando Valadares, Kyle Timothy Ng Chu +6
Quantum harmonic oscillators serve as fundamental building blocks for quantum information processing, particularly in the context of the bosonic circuit quantum electrodynamics (cQ…
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…
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…
Genuine quantum non-Gaussianity and metrological sensitivity of Fock states prepared in a mechanical resonator
Q. Rumman Rahman, Igor KladariÄ, 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…
Quantum non-Gaussianity of light and atoms
Lukáš Lachman, Radim Filip
Quantum non-Gaussian states of photons and phonons are conclusive and direct witnesses of higher-than-quadratic nonlinearities in optical and mechanical processes. Moreover, they a…
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…
