A quantum logic gate between a solid-state quantum bit and a photon
Hyochul Kim, Ranojoy Bose, Thomas C. Shen +2
Integrated quantum photonics provides a promising route towards scalable solid-state implementations of quantum networks, quantum computers, and ultra-low power opto-electronic dev…
Attojoule all-optical switching with a single quantum dot
Deepak Sridharan, Ranojoy Bose, Hyochul Kim Glenn S. Solomon +1
We experimentally investigate the dynamic nonlinear response of a single quantum dot (QD) strongly coupled to a photonic crystal cavity-waveguide structure. The temporal response i…
Suppression of off-resonant cavity feeding through quasi-resonant pumping in a strongly coupled cavity-quantum dot system
Deepak Sridharan, Ranojoy Bose, Glenn S. Solomon +1
We compare the photoluminescence spectrum of an indium arsenide (InAs) quantum dot (QD) that is strongly coupled to a photonic crystal cavity under above band excitation (ABE) and…
Cryogenic spectroscopy of ultra-low density colloidal lead chalcogenide quantum dots on chip-scale optical cavities towards single quantum dot near-infrared cavity QED
Ranojoy Bose, Jie Gao, James F. McMillan +2
We present evidence of cavity quantum electrodynamics from a sparse density of strongly quantum-confined Pb-chalcogenide nanocrystals (between 1 and 10) approaching single-dot leve…
Nanocrystals in silicon photonic crystal standing-wave cavities as spin-photon phase gates for quantum information processing
Yun-Feng Xiao, Jie Gao, Xiaodong Yang +3
By virtue of a silicon high-Q photonic crystal nanocavity, we propose and examine theoretically interactions between a stationary electron spin qubit of a semiconductor nanocrystal…
