Impact of photon addition and subtraction on nonclassical and phase properties of a displaced Fock state
Priya Malpani, Kishore Thapliyal, Nasir Alam +3
Various nonclassical and quantum phase properties of photon added then subtracted displaced Fock state have been examined systematically and rigorously. Higher-order moments of the…
Manipulating nonclassicality via quantum state engineering processes: Vacuum filtration and single photon addition
Priya Malpani, Nasir Alam, Kishore Thapliyal +3
The effect of two quantum state engineering processes that can be used to burn hole at vacuum in the photon number distribution of quantum states of radiation field are compared us…
Quantum phase properties of photon added and subtracted displaced Fock states
Priya Malpani, Kishore Thapliyal, Nasir Alam +3
Quantum phase properties of photon added and subtracted displaced Fock states (and a set of quantum states which can be obtained as the limiting cases of these states) are investig…
Generalized binomial state: Nonclassical features observed through various witnesses and a measure of nonclassicality
Kathakali Mandal, Nasir Alam, Amit Verma +2
Experimental realization of various quantum states of interest has become possible in the recent past due to the rapid developments in the field of quantum state engineering. Noncl…
Lower- and higher-order nonclassical properties of photon added and subtracted displaced Fock states
Priya Malpani, Nasir Alam, Kishore Thapliyal +3
Nonclassical properties of photon added and subtracted displaced Fock states have been studied using various witnesses of lower- and higher-order nonclassicality. Compact analytic…
Higher-order nonclassical properties of a shifted symmetric cat state and a one-dimensional continuous superposition of coherent states
Nasir Alam, Kathakali Mandal, Anirban Pathak
Role of quantum interference in the origin of higher-order nonclassical characteristics of radiation field has been probed vis-a-vis a discrete and a continuous superposition of co…
Higher order nonclassicalities of finite dimensional coherent states: A comparative study
Nasir Alam, Amit Verma, Anirban Pathak
Conventional coherent states (CSs) are defined in various ways. For example, CS is defined as an infinite Poissonian expansion in Fock states, as displaced vacuum state, or as an e…
Lower- and higher-order nonclassicality in a Bose-condensed optomechanical-like system and a Fabry-Perot cavity with one movable mirror: squeezing, antibunching and entanglement
Nasir Alam, Kishore Thapliyal, Anirban Pathak +3
Various lower- and higher-order nonclassical properties have been studied for two physical systems- (i) an optomechanical system composed of a Fabry-Perot cavity with one nonlinear…
Orthogonal-state-based protocols of quantum key agreement
Chitra Shukla, Nasir Alam, Anirban Pathak
Two orthogonal-state-based protocols of quantum key agreement (QKA) are proposed. The first protocol of QKA proposed here is designed for two-party QKA, whereas the second protocol…
