Continuous variable quantum teleportation, invariant squeezing and non-Gaussian resource states
Mohak Sharma, Chandan Kumar, Shikhar Arora +1
We investigate the role of quadrature squeezing in the quantum teleportation protocol for coherent states, using non-Gaussian resource states. For the two-mode systems, the non-Gau…
Continuous variable quantum teleportation using photon subtracted and photon added two mode squeezed coherent state
Shikhar Arora, Chandan Kumar, Arvind
We consider non-Gaussian states generated by photon subtraction (PS) and photon addition (PA) on two-mode squeezed coherent (TMSC) states, as resource states for continuous variabl…
Continuous variable quantum teleportation in a dissipative environment: Comparison of non-Gaussian operations before and after noisy channel
Chandan Kumar, Mohak Sharma, Shikhar Arora
We explore the relative advantages in continuous-variable quantum teleportation when non-Gaussian operations, namely, photon subtraction, addition, and catalysis, are performed bef…
Parity-detection-based Mach-Zehnder interferometry with coherent and non-Gaussian squeezed vacuum states as inputs
Chandan Kumar, Rishabh, Mohak Sharma +1
We theoretically explore the advantages rendered by non-Gaussian operations in phase estimation using a parity-detection-based Mach-Zehnder interferometer, with one input being a c…
Enhanced phase estimation in parity detection based Mach-Zehnder interferometer using non-Gaussian two-mode squeezed thermal input state
Chandan Kumar, Rishabh, Shikhar Arora
While the quantum metrological advantages of performing non-Gaussian operations on two-mode squeezed vacuum (TMSV) states have been extensively explored, similar studies in the con…
Consideration of success probability and performance optimization in non-Gaussian continuous variable quantum teleportation
Chandan Kumar, Shikhar Arora
Non-Gaussian operations have been shown to enhance the fidelity of continuous variable quantum teleportation. However, a disadvantage of these non-Gaussian operations is that they…

Chandan Kumar, Rishabh, Shikhar Arora
We theoretically analyze phase sensitivity using parity detection based Mach Zehnder interferometer (MZI) with the input states generated by performing non-Gaussian operations, viz…
