Laboratory for Bits & Waves
The quantum information processing group at BBN Technologies focuses on exploiting quantum phenomena for sensing, computing and imaging. Our work spans fundamental physics research up to prototype integrated systems.
Laboratory of Quantum Optics
PPKTP-based Source of Entangled Photons
We are building a PPKTP-based source of entangled photons. The time-energy entangled photon pairs are generated in the 1550-nm wavelength band.
Laboratory of Quantum Electronics
BBN's quantum information processing group has several platforms for low-temperature experiments, including two 3-4K cryo-coolers and three cryo-free dilution refrigerators achieving a base temperature of ~10 mK. At these temperatures we can study "artificial atoms", engineered electrical circuits that exhibit manifestly quantum behavior. These circuits enable small quantum processors and novel quantum optics experiments with microwave photons.
