We propose an autonomous quantum error correction scheme using squeezed cat (SC)
code against excitation loss in continuous-variable systems. Through reservoir engineering …

The pair-coherent state (PCS) is a theoretical extension of the Glauber coherent state to two
harmonic oscillators. It is an interesting class of non-Gaussian continuous-variable …

An important outstanding challenge that must be overcome in order to fully utilize the XY
surface code for correcting biased Pauli noise is the phenomenon of fragile temporal …

Continuous-variable cat codes are encodings into a single photonic or phononic mode that
offer a promising avenue for hardware-efficient fault-tolerant quantum computation …

The family of two-mode non-Gaussian entangled states, including the pair coherent states
(PCSs) and their genealogies, has been extensively investigated regarding their quantum …

Gaussian quantum information processing with continuous-variable (CV) quantum
information carriers holds significant promise for applications in quantum communication …

This thesis concerns the theoretical study of quantum key distribution and quantum error
correction implemented with bosonic systems. The former is referred to as continuous …
