Quantum non-Gaussian high Fock states of light pulses and their superpositions
G. P. Teja, Chandan Kumar, Lukáš Lachman +1
The generation of high Fock states of light pulses and their superpositions with provable quantum non-Gaussian features is still very challenging, although the power of conditional…
Husimi phase distribution in non-Gaussian operations
Ramniwas Meena, Chandan Kumar, Subhashish Banerjee
The Husimi phase distribution, an experimentally measurable quantity, is investigated for single-mode and two-mode squeezed vacuum states. The analysis highlights that non-Gaussian…
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…
Re-examination of the role of displacement and photon catalysis operation in continuous variable measurement device-independent quantum key distribution
Chandan Kumar, Arvind
We investigate the benefits of using -photon catalysed two-mode squeezed coherent (-PCTMSC) state in continuous variable measurement device-independent quantum key distributi…
Optimization of state parameters in displacement assisted photon subtracted measurement-device-independent quantum key distribution
Chandan Kumar, Sarbani Chatterjee, Arvind
Non-Gaussian operations, in particular, photon subtraction (PS), have been shown to enhance the performance of various quantum information processing tasks including continuous var…
No real advantage of photon subtraction and displacement in continuous variable measurement device independent quantum key distribution
Chandan Kumar, Sarbani Chatterjee, Arvind
We critically analyse the role of single photon subtraction (SPS) and displacement in improving the performance of continuous variable measurement device independent quantum key di…
Non-Gaussian two mode squeezed thermal states in continuous variable quantum teleportation
Chandan Kumar
While photon catalyzed two mode squeezed vacuum state has been considered in context of quantum teleportation, similar studies have not been yet conducted for photon catalyzed two-…
