Nonlinear squeezing of superpositions of quadrature eigenstates
Vojtěch Kuchař, Petr Marek
We introduce a family of operators exploiting the symmetry of superpositions of quadrature eigenstates (SQE) and demonstrate how the associated nonlinear squeezing, quantified by t…

Ground state nature and nonlinear squeezing of Gottesman-Kitaev-Preskill states
Petr Marek
The main bottleneck for universal quantum computation with traveling light is the preparation of Gottesman-Kitaev-Preskill states of sufficient quality. This is an extremely challe…

Characterization of the entanglement of two squeezed states
P. Marek, M. S. Kim, M. Paternostro
We study a continuous-variable entangled state composed of two states which are squeezed in two opposite quadratures in phase space. Various entanglement conditions are tested for…
