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…
Temperature dependent maximization of work and efficiency in a degeneracy assisted quantum Stirling heat engine
Sarbani Chatterjee, Arghadip Koner, Sohini Chatterjee +1
We propose a quantum Stirling heat engine with an ensemble of harmonic oscillators as the working medium. We show that the efficiency of the harmonic oscillator quantum Stirling he…
