Non-Gaussian entanglement revealed by higher-order quadrature cumulants
Abhinav Verma, Olga Solodovnikova, Jonas S. Neergaard-Nielsen +1
Entanglement is central to quantum physics, yet detecting and exploiting it in non-Gaussian systems remains a major challenge. In continuous variable platforms, standard inseparabi…
Optical states with higher stellar rank
Jan ProvaznÃk, Olga Solodovnikova, Radim Filip +1
Quantum non-Gaussian states of traveling light fields are crucial components of quantum information processing protocols; however, their preparation is experimentally challenging.…
The loss tolerance of cat breeding for fault-tolerant grid state generation
Olga Solodovnikova, Ulrik L. Andersen, Jonas S. Neergaard-Nielsen
The development of a continuous-variable photonic quantum computer depends on the reliable preparation of high-quality Gottesman-Kitaev-Preskill states. The most promising GKP prep…
Fast simulations of continuous-variable circuits using the coherent state decomposition
Olga Solodovnikova, Ulrik L. Andersen, Jonas S. Neergaard-Nielsen
We present \texttt{lcg\_plus}, an open-source Python library for the simulation of continuous-variable quantum circuits with both generaldyne and photon-number-resolving detector c…
