Travelling Dark State Polariton as a Viable Quantum Memory in a Solid-State Medium
Avirup Chakraborty, Shrabana Chakrabarti
We theorize a quantum memory based on the dark-state polariton field, formed by the superposition of atomic and photonic states of a travelling probe laser pulse under the applicat…
Quantum-RAM Implementation Using Multiple Interacting Rydberg-Blockaded EIT Systems
Avirup Chakraborty, Shrabana Chakrabarti
We propose a novel theoretical architecture for implementing a quantum random access memory (qRAM) based on quantum random walks in a Rydberg blockaded atomic ensemble utilizing mu…
Quantum Random Access Memory Implementation Using Photon-Photon Interaction in Rydberg Atomic Ensemble
Avirup Chakraborty, Shrabana Chakrabarti
Quantum random access memory (qRAM) is crucial for overcoming data-loading bottlenecks in quantum machine learning; however, current physical implementations face severe scalabilit…
Interplay between electromagnetically induced transparency(EIT), absorption (EIA) and Autler-Townes (AT) splitting in N-type atomic system: An experiment and theory
Bankim Chandra Das, Arpita Das, Dipankar Bhattacharyya +2
In this article we have shown that the atomic states can be engineered by tunning the coupling Rabi frequency for a system with -type configuration. Electromagneticall…
Pulse delay and group velocity dispersion measurement in V-type electromagnetically induced transparency of hot atom
Bankim Chandra Das, Dipankar Bhattacharyya, Arpita Das +3
Pulse delay with the group velocity dispersion (GVD) characteristics was studied in the V-type electromagnetically induced transparency in the hyperfine levels of atoms w…
