By Center for Functional Nanomaterials Brookhaven
The Instrumentation Department works at the forefront of quantum information science and technology (QIST), using quantum physics to develop all-new and potentially revolutionary technologies. Our primary focus is quantum networking, a national priority and the basis for a secure quantum internet of the future. We are also pursuing ways of improving existing detection systems, from astronomy to LIDAR, by applying quantum technologies. We work in close collaboration with the QIST group at Stony Brook University. Our Capabilities: - Arrangement of large optical assemblies via three full-sized enclosed optical tables with climate control - Generation of quantum entanglement with a portable polarization-entangled photon pair source - Deployment of quantum communication hardware, including rack-mounted telecom laser sources and second harmonic generation systems; cavity-based telecom entanglement sources using high-finesse bow-tie cavities; and rack-mounted single-photon-detection systems for telecom wavelengths - Detection of single photons by a multichannel infrared-sensitive superconducting nanowire single-photon detector (SNSPD) from Single Quantum EoS - Refrigeration at millikelvin temperatures through a low-vibration dilution refrigerator setup equipped with microwave capabilities and free-space and fiber-coupled optical access - Control and readout of qubits with cryogenic integrated electronics - Development of cryogenic technology for superconducting interconnects
