A physical and universal model of bosonic computations with Solovay-Kitaev theorem
Dorian Rudolph, Arsalan Motamedi, Dhruva Sambrani +4
Bosonic quantum systems are among the leading architectures for quantum information processing, offering continuous-variable degrees of freedom with strong error-correction capabil…
Differential hierarchy of the Husimi representation
Zacharie Van Herstraeten, Ulysse Chabaud
Phase-space representations reveal the geometry of quantum mechanics and distinguish quantum features from classical ones. However, the positivity of a density operator is among th…
Wigner-positive quantum states can have lower entropy than the vacuum
Zacharie Van Herstraeten, Nicolas J. Cerf, Ulysse Chabaud
The Wigner entropy conjecture posits that pure Gaussian states minimize the Shannon entropy of non-negative Wigner functions, known as the Wigner entropy. We show that mixing a spe…
Rigorous characterization of continuous-variable quantum states via optical parametric amplifiers
Manthan Badbaria, Fumiya Hanamura, Maxime Garnier +2
Characterizing non-Gaussian quantum states is of paramount importance for continuous-variable quantum information processing, yet conventional homodyne-measurement-based state tomo…
Improved GKP magic states from error-corrected non-Gaussian quantum states
Sharon David, Jack Davis, Ulysse Chabaud +1
Gate teleportation, together with magic state distillation, is a promising route towards fault-tolerant, universal computation. In the context of bosonic quantum computation, Barag…
Bosonic quantum error-correcting codes with finite stellar rank
Rui Wang, Adithi Udupa, Timo Hillmann +3
Bosonic quantum error correction (QEC) relies on non-Gaussian bosonic encodings whose preparation cost is a central practical constraint. In this work, we use stellar rank as a res…
