Towards a spectrally multiplexed quantum repeater
Tanmoy Chakraborty, Antariksha Das, Hedser van Brug +5
Extended quantum networks are based on quantum repeaters that often rely on the distribution of entanglement in an efficient and heralded fashion over multiple network nodes. Many…
Spectrally Multiplexed Hong-Ou-Mandel Interference
Oriol Pietx-Casas, Gustavo Castro do Amaral, Tanmoy Chakraborty +4
We explore the suitability of a Virtually-Imaged Phased Array (VIPA) as a Spectral-to-Spatial Mode-Mapper (SSMM) for applications in quantum communication such as a quantum repeate…
Trends in elastic properties of Ti-Ta alloys from first-principles calculations
