Performance of a two-mode coherent superposed channel in continuous-variable quantum teleportation
Deepak, Arpita Chatterjee
Glauber's coherent state is denoted by and its two-mode extension is represented by . In this work, we introduce a two-mode superposition operator $A=tab+ra^\dag…
Analyzing performance of -deformed displaced Fock state in continuous-variable quantum teleportation
Deepak, Arpita Chatterjee
Performing non-Gaussian operations, namely photon addition, photon subtraction, photon-addition-then-subtraction, photon-subtraction-then-addition can successfully enhance the fide…
Detecting Nonclassicality and quantum non-Gaussianity of photon subtracted displaced Fock state
Deepak, Arpita Chatterjee
In this paper, a quantitative investigation of the non-classical and quantum non-Gaussian characters of the photon-subtracted displaced Fock state , w…
Lower-vs-Higher Order Non-classicality of Photon-added Bell-type Entangled Coherent States
Deepak, Arpita Chatterjee
We compare the lower and higher order non-classicality of a class of the photon-added Bell-type entangled coherent states (PBECS) got from Bell-type entangled coherent states using…
General expansion of natural power of linear combination of Bosonic operators in normal order
Deepak, Arpita Chatterjee
In quantum mechanics, bosonic operators are mathematical objects that are used to represent the creation () and annihilation () of bosonic particles. The natural powe…
A comparative study of higher-order nonclassicalities of photon-added-then-subtracted and photon-subtracted-then-added quantum states
Deepak, Arpita Chatterjee
In the present paper, we have studied the higher as well as the lower-order nonclassicalities of photon-added-then-subtracted and photon-subtracted-then-added thermal and even cohe…
Nonclassical properties of a deformed atom-cavity field state
Naveen Kumar, Deepak, Arpita Chatterjee
We analyze here a nonclassical state produced by an atom-cavity field interaction. The two-level atom is passed through the single-mode electromagnetic cavity field. By deforming t…
Detecting nonclassicality and non-Gaussianity of a coherent superposed quantum state
Deepak, Arpita Chatterjee
In this paper, we investigate the nonclassicality and non-Gaussianity of a coherent superposed quantum state (CSQS) which is obtained by applying a coherent superposition of field…
Realistic continuous-variable quantum teleportation using a displaced Fock state channel
Deepak, Arpita Chatterjee
We investigate ideal and non-ideal continuous-variable quantum teleportation protocols realized by using an entangled displaced Fock state resource. The characteristic function for…
Lower- versus higher-order nonclassicalities for a coherent superposed quantum state
Deepak, Arpita Chatterjee
A coherent state is defined conventionally in different ways such as a displaced vacuum state, an eigenket of annihilation operator or as an infinite dimensional Poissonian superpo…
