QPL Presents at the 2022 CLEO Conference!
We're excited to be back at CLEO with three talks throughout the week by Shaimaa, Josh, and Trevor!
Some great results coming out of our group will be presented by Josh, Shaimaa, and Trevor on integrated quantum photonics and applications in quantum computing and cryptography. We're looking forward to attend the many other interesting talks throughout the week, especially in the FS3: Quantum Photonics Sessions!
M3H.4 (11:30-11:45AM Monday, May 16)
Control of Single-Photon Emitters in two-Dimensional Materials Using Dielectric Nanoantennas
Presenter: Shaimaa Azzam, UC Santa Barbara, United States
We show that dielectric nanoantennas are capable of inducing very high Purcell enhancement up to factors > 45 for defect-based single-quantum emitters in atomically thin layered materials, enabling bright single-photon emission with polarization control. Authors: Shaimaa Azzam, UC Santa Barbara / Kamyar Parto, UC Santa Barbara / Galan Moody, UC Santa Barbara
SF3G.1 (10:30-10:45AM Friday, May 20)
Expanding the Quantum Photonic Toolbox With Low-Loss AlGaAs-on-Insulator
Presenter: Joshua Castro, UC Santa Barbara, United States
We present the building blocks for a programmable quantum processor with AlGaAs-on-insulator integrated photonics, including low-loss waveguide crossers and $>30$ dB extinction tunable interferometers, which we benchmark via photonic qubit demultiplexing with high extinction. Authors: Joshua Castro, UC Santa Barbara / Trevor Steiner, UC Santa Barbara / Lin Chang, UC Santa Barbara / Paolo Pintus, UC Santa Barbara / John Bowers, UC Santa Barbara / Galan Moody, UC Santa Barbara
FF4J.5 (3:30-3:45PM, Friday, May 20)
AlGaAsOI Photonics and Low-Loss Links for High-Speed Entanglement-Based Quantum Key Distribution
Presenter: Trevor Steiner, University of California, United States
We report a record-high detected entangled-photon pair coincidence rate from an AlGaAs-on-insulator microring resonator with raw coincidence rates >19 kHz that is capable of time-bin entanglement-based QKD with an estimated secure key rate of 1.4 kbits/second. Authors: Trevor Steiner, University of California / Joshua Castro, University of California / Alex Dinkelacker, University of California / Lin Chang, University of California / John Bowers, University of California / Galan Moody, University of California
