Higher-order covariance matrices for non-Gaussian quantum states
Vojtěch Kala, Petr Marek, Nicolas J. Cerf
Covariance matrices lie at the heart of the powerful and well-established symplectic framework for describing continuous-variable Gaussian quantum states. However, since this frame…
Picosecond Schrödinger cat states for ultrafast optical quantum processing
Mamoru Endo, Kan Takase, Takefumi Nomura +12
Non-Gaussian states are essential resources for universal, fault-tolerant optical quantum computing, but their generation rate remains limited by low heralding probabilities and op…
Generalization of catability for parity-less cat states
Michal Matulík, Jan Provazník, Petr Marek +1
We extend the nullifier-based certification framework of catability from parity-defined coherent cat states to parity-less Kerr cat states. Since Kerr cats cannot be distinguished…
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…
Witnesses of non-Gaussian features as lower bounds of stellar rank
Jan Provazník, Šimon Bräuer, Vojtěch Kala +2
Quantum non-Gaussian states and operations serve as fundamental resources for universal quantum computation, error correction, and high-precision metrology, extending beyond the Ga…
Tuning Wave-Particle Duality of Quantum Light by Generalized Photon Subtraction
Kan Takase, Mamoru Endo, Fumiya Hanamura +11
Wave--particle duality is a hallmark of quantum mechanics. For bosonic systems, there exists a continuum of intermediate states bridging wave-like Schrödinger cat states and partic…
