SIPQNP 2016

Dates: March 31 – April 1, 2016
Location: Raytheon Corporate Headquarters, Waltham, MA
Sponsored by: Raytheon BBN Technologies

Overview: The 3rd SIPQNP, held in 2016, started with a two-part theory session, focusing on photonic quantum computing and quantum key distribution respectively — with overview talks and moderated discussions for each. This was followed by two experiments-and-devices centric sessions: one on integrated photonic devices, and the other on bulk optics and single photon / number resolving detector technologies. The workshop ended with a few hour-long topical discussions on single-photon nonlinearities, novel optical quantum encoding formats, and quantum networking.
