Efficient circuit compression by multiqudit entangling gates in linear optical quantum computation
Apurav Tehri, Jaskaran Singh
Linear optical quantum computation (LOQC) offers a promising platform for scalable quantum information processing, but its scalability is fundamentally constrained by the probabili…
Arbitrary vector beam generation in semiconductor quantum dots
Samit Kumar Hazra, P. K. Pathak, Tarak Nath Dey
We have proposed an arbitrary vector beam (VB) generation scheme in a thin disk-shaped quantum dot (QD) medium considering phonon interaction. The QD biexciton system exhibits inte…
Nondegenerate two-photon lasing in a single quantum dot
Samit Kumar Hazra, Lava Kumar Addepalli, P. K. Pathak +1
We propose two-mode two-photon microlaser using a single semiconductor quantum dot grown inside a two-mode microcavity. We explore both incoherent and coherent pumping at low tempe…
Deterministic generation of hybrid entangled states using quantum walks
Jaskaran Singh, Vikash Mittal, Soumyakanti Bose
In recent times, hybrid-entanglement (HE) between a qubit and a coherent state has demonstrated superior performance in various quantum information processing tasks, particularly i…
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…
Transition time estimation for -function coupling in two state problem: An analytically solvable model
Mayank Vashistha, Chinmoy Samanta, Aniruddha Chakraborty
We propose a simple method to calculate transition time in a two-state scattering problem, where two constant potentials are coupled by a delta function potential $V_{12}=V_{21}=k_…
