Classical-to-quantum transfer of geometric phase for non-interferometric phase measurement and manipulation of quantum state
Vimlesh Kumar, Chahat Kaushik, M. Ebrahim-Zadeh +2
The geometric phase, originating from the cyclic evolution of a state, such as polarization on the Poincaré sphere, is typically measured through interferometric approaches that o…
Device-independent, megabit-rate quantum random number generator with beam-splitter-free architecture and live Bell test certification
Ayan Kumar Nai, Vimlesh Kumar, M. Ebrahim-Zadeh +1
Device-independent quantum random number generators (DI-QRNGs) are crucial for information processing, ensuring certified quantumness and genuine randomness. However, existing impl…
Mean-field equation for phase-modulated optical parametric oscillator
A. D. Sanchez, S. Chaitanya Kumar, M. Ebrahim-Zadeh
The widely established techniques for the generation of ultrashort optical pulses rely on passive mode-locking of lasers, with the output pulse duration and emission spectrum deter…
Quadratic frequency comb based on phase-modulated cw-driven optical parametric oscillator with intracavity dispersion control
A. D. Sanchez, S. Chaitanya Kumar, M. Ebrahim-Zadeh
We report a novel configuration of bulk optical parametric oscillator (OPO) capable of delivering coherent broadband phase-locked spectrum when driven by a continuous-wa…
CUDA-based focused Gaussian beams second-harmonic generation efficiency calculator
A. D. Sanchez, S. Chaitanya Kumar, M. Ebrahim-Zadeh
We present an object-oriented programming (OOP) CUDA-based package for fast and accurate simulation of second-harmonic generation (SHG) efficiency using focused Gaussian beams. The…
CUDA-based optical parametric oscillator simulator
Alfredo Daniel Sanchez, Chaitanya Kumar Suddapalli, Majid Ebrahim-Zadeh
The coupled-wave equations (CWEs) in nonlinear optics are the fundamental starting point in the study, analysis, and understanding of various frequency conversion processes in diel…
