Compact narrowband photon-pair generation by slow-light spectral engineering
Ashwith Prabhu, Elizabeth A. Goldschmidt
Efficiently generating photon pairs with high heralding efficiency and high single photon purity that are bandwidth matched to quantum emitters, quantum memories, and other matter-…
Telecom quantum memory over one microsecond in nanophotonic lithium niobate
Priyash Barya, Daren Chen, Ashwith Prabhu +9
Nanophotonic quantum memory is a vital component for scalable quantum information processing for quantum computing, networking, and sensing applications. We store single-photon-lev…
Ultra High-Q tunable microring resonators enabled by slow light
Priyash Barya, Ashwith Prabhu, Laura Heller +2
High-Q nanophotonic resonators are crucial for many applications in classical and quantum optical processing, communication, sensing, and more. We achieve ultra-high quality factor…
Narrow optical linewidths in stoichiometric layered rare-earth crystals
Donny R. Pearson, Ashwith Prabhu, Selvin Tobar +5
Rare-earth emitters in solids are well-suited for implementing efficient, long-lived quantum memory coupled to integrated photonics for scalable quantum technologies. They are typi…
Quantum Electrodynamics with Time-varying Dielectrics
Ashwith Prabhu, Jennifer Parra-Contreras, Elizabeth A. Goldschmidt +1
We present a framework for quantization of electromagnetic field in the presence of dielectric media with time-varying optical properties. Considering a microscopic model for the d…
Hyperentanglement-enhanced quantum illumination
Ashwith Varadaraj Prabhu, Baladitya Suri, C. M. Chandrashekar
In quantum illumination, the signal mode of light, entangled with an idler mode, is dispatched towards a suspected object bathed in thermal noise and the returning mode, along with…
