- Authors: Sandip Kumar Giri and Biswajit Sen
- Abstract summary: We consider a hybrid coherent state (HCS), which is a coherent superposition of the single-photon-added coherent (SPAC) state and a coherent state (CS)
It's shown that HCS is experimentally realizable, and this engineered quantum state can be used to produce quantum states with desired higher-order nonclassical properties.

- Abstract: In the development of quantum technologies, nonclassical states have been
playing a pivotal role, as quantum advantage cannot be obtained without
appropriate utilization of nonclassicality. In the present work, we consider a
hybrid coherent state (HCS), which is a coherent superposition of the
single-photon-added coherent (SPAC) state and a coherent state (CS). Here, we
report higher-order nonclassical properties of HCS with a specific focus on
higher-order squeezing and higher-order antibunching. It's shown that HCS is
experimentally realizable, and this engineered quantum state can be used to
produce quantum states with desired higher-order nonclassical properties.
