Observation of Subnatural-Linewidth Biphotons In a Two-Level Atomic Ensemble
Jyun-Kai Lin, Tzu-Hsiang Chien, Chin-Te Wu +4
Biphotons and single photons with narrow bandwidths and long coherence times are essential to the realization of long-distance quantum communication (LDQC) and linear optical quant…
Entanglement preservation in tripartite quantum systems under dephasing dynamics
Chandrashekar Radhakrishnan, Sovik Roy, Ravikumar Chinnarasu +1
Protecting entanglement from decoherence is a critical aspect of quantum information processsing. For many-body quantum systems evolving under decoherence, estimating multipartite…
Efficient Generation of Subnatural-Linewidth Biphotons by Controlled Quantum Interference
Ravikumar Chinnarasu, Chi-Yang Liu, Yi-Feng Ding +4
Biphotons of narrow bandwidth and long temporal length play a crucial role in long-distance quantum communication (LDQC) and linear optical quantum computing (LOQC). However, gener…
Shaping single photons and biphotons by inherent losses
Wei-Ming Su, Ravikumar Chinnarasu, Chang-Hau Kuo +1
Inherent loss is always to be avoided in generating single photons or biphotons, but interestingly it provides opportunities for manipulating the photon wave packet. In this paper…
A Fractional entropy in Fractal phase space: properties and characterization
R. Chandrashekar, C. Ravikumar, J. Segar
A two parameter generalization of Boltzmann-Gibbs-Shannon entropy based on natural logarithm is introduced. The generalization of the Shannon-Kinchinn axioms corresponding to the t…
