AFRL/RITQ - Superconducting and Hybrid Quantum Systems SUPERCONDUCTING QUBIT AND QUANTUM INTERFACE PLATFORMS FOR QUANTUM NETWORKING The superconducting and hybrid quantum systems team at AFRL’s Information Directorate (RI) in Rome, New York seeks to develop novel superconducting architectures and cross-modality quantum interface hardware as building blocks for use in quantum networks. The team’s efforts focus on three main thrusts: (i) the development of architectures for generating entanglement between multi-qubit superconducting modules (i.e. encoding/decoding multi-partite quantum information on a quantum bus). (ii) the investigation of hybrid superconducting and photonic platforms for transduction of quantum information between microwave and optical domains at cryogenic temperatures; (iii) and development of quantum interface hardware for bridging trapped ion and superconducting qubit modalities. The above left and middle images show a piezo-optomechanical transducer chip obtained from a collaboration with Sunil Bhave's group at Purdue University. The chip has electrical wirebonds and has optical fiber v-groove arrays bonded to it and is mounted in a sample package for placement inside a dilution refrigerator. The above right Image shows a piezo-optomechanical transducer chip (same as above), with single optical fibers bonded to it, and mounted within the team's Bluefors LD dilution refrigerator. (U.S. Air Force photos) The superconducting team is working in conjunction with AFRL’s trapped ion and integrated photonics teams to pursue development of such architectures and interconnects.
