Self-induced Transparency in a Semiconductor Quantum Dot medium at ultra-cold temperatures
Samit Kumar Hazra, P. K. Pathak, Tarak Nath Dey
We investigate the feasibility of minimum absorption and minimum broadening of pulse propagation in an inhomogeneously broadened semiconductor quantum dot medium. The phonon intera…
Effect of phonon coupling on cooperative two-photon emission from two-quantum dots
J. K. Verma, Harmanpreet Singh, P. K. Pathak
We predict dominating cooperative two-photon emission from two quantum dots coupled with a single mode photonic crystal cavity. The cooperative two photon emission occurs when exci…
Effect of phonon coupling on the generated entangled states of photons from a single quantum dot embedded inside a microcavity
J. K. Verma, Harmanpreet Singh, P. K. Pathak
We discuss the generation of two types of entangled state of two photons-- noon state which is entangled in number and polarization, and polarization entangled state which is entan…
Generation of the superposition of mesoscopic states of nano-mechanical resonator by a single two-level system
Manoj Das, J. K. Verma, P. K. Pathak
We propose measurement based conditional generation of superposition of motional states of nanomechanical resonator. We consider a two level quantum mechanical system coupled with…
Generation of time-bin entangled photon pairs using a quantum-dot cavity system
P. K. Pathak, S. Hughes
We present a scheme to realize a deterministic solid state source of time-bin entangled photon pairs using cavity-assisted stimulated Raman adiabatic passage (STIRAP) in a single q…
Generation of "triggered single photons" from a coherently-pumped quantum dot
P. K. Pathak, S. Hughes
A deterministic "on demand" source of single photons is a basic building block for linear quantum computation \cite{linear}, quantum cryptography \cite{crypto}, quantum teleportati…
