Entangling Superconducting Qubits over Optical Fiber - Towards Optimization and Implementation

November 22, 2022
Author(s)
Curtis Rau, Akira Kyle, Alexander Kwiatkowski, Will Warfield, Jacob Davidson, Maxime Nurwubusa, John Teufel, Ezad Shojaee, Konrad Lehnert, Tasshi Dennis
A quantum network linking superconducting quantum computers would enable highly sought-after applications such as distributed quantum computing. Optical photons are the natural way of encoding information for long distance communication; however

Entanglement Thresholds of Doubly Parametric Quantum Transducers

April 29, 2022
Author(s)
Curtis Rau, Akira Kyle, Alexander T. Kwiatkowski, Ezad Shojaee, John Teufel, Konrad Lehnert, Tasshi Dennis
Doubly parametric quantum transducers, such as electro-optomechanical devices, show promise for providing the critical link between quantum information encoded in highly disparate frequencies such as in the optical and microwave domains. This technology

Optical Fiber Time Delay Comparison between NIST and LAMETRO

January 10, 2022
Author(s)
Tasshi Dennis, Johnny Jimenez
We describe the results of a bilateral measurement comparison of optical fiber time delay between the National Institute of Standards and Technology (NIST, USA) and Laboratorio de Metrología, Instituto Costarricense de Electricidad (LAMETRO-ICE, Costa Rica

A Programmable Solar Simulator for Realistic Seasonal, Diurnal, and Air-Mass Testing of Multi-Junction Concentrator Photovoltaics

June 4, 2016
Author(s)
Tasshi Dennis, chanud yasanayake, Tim Gerke, Alex Payne, Lars Eng, brent fisher, Matt Meitl
We built a spectrally programmable super-continuum solar simulator and applied it to the realistic laboratory testing of a multi-junction concentrator solar cell. The novel simulator generated a broad range of illumination conditions representing changes

Saturation in Solar Cells from Ultra-Fast Pulsed-Laser Illumination

June 4, 2016
Author(s)
Tasshi Dennis
We investigate the potential saturation of a silicon solar cell in response to excitation from continuous-wave and ultra-fast pulsed lasers of equivalent average optical power. Because ultra-fast pulsed sources such as the super-continuum laser have very

A novel solar simulator based on a super-continuum laser

June 3, 2012
Author(s)
Tasshi Dennis, John B. Schlager, Hao-Chih Yuan, Qi Wang, Daniel Friedman
The design and operation of a novel solar simulator based on a high-power, super-continuum fiber laser is described in this work. The simulator features a multi-sun irradiance with continuous spectral coverage from the visible to the infrared. By use of a
