Full-Wave Modeling of Microwave Frequency Single Photon Sources
08 Jul 2021 | | Contributor(s):: Thomas Roth
In this talk, we present preliminary results on how fully classical computational electromagnetics methods can be leveraged to more fully characterize the performance of single photon sources. To make the development more concrete, we specifically focus on modeling a microwave frequency single...
Nonlinear Quantum Electrodynamics in Dirac Materials
29 Apr 2021 | | Contributor(s):: Yuli Lyanda-Geller
We show that similar nonlinear effects arise in Dirac materials at much lower fields, the magnitude of the effects is significant, and they can be observed in laboratory experiments. We predict and calculate the nonlinear electromagnetic effects and discuss compounds where the nonlinear...
Fundamental Properties of a New van der Waals Material: Tellurium
01 Apr 2021 | | Contributor(s):: Peide "Peter" Ye
We report the first experimental observation of Weyl fermions in a semiconductor -- high-quality n-type tellurene (the two-dimensional form of tellurium) achieved by atomic layer deposited dielectric doping.

Designing a NISQ Reservoir with Maximal Memory Capacity for Volatility Forecasting
28 Oct 2020 | | Contributor(s):: Samudra Dasgupta
In this talk, we lay out the systematic design considerations for using a NISQ reservoir as a computing engine. We then show how to experimentally evaluate the memory capacity of various reservoir topologies (using IBM-Q’s Rochester device) to identify the configuration with maximum...
Physics and Computation (with Nuclear Spins)
21 May 2020 | | Contributor(s):: Gerardo Ortiz
There is a deep connection between Physics and Computation. Indeed, any computation can be represented as a physical process. In 1981 Richard Feynman raised some provocative questions in connection to the simulation of physical phenomena using a special device called a "Quantum...
Exploring Synthetic Quantum Materials in Superconducting Circuits
30 Apr 2020 |
Superconducting circuits have emerged as a competitive platform for quantum computation, satisfying the challenges of controllability, long coherence and strong interactions. I will show our recent experiments to apply this toolbox to the exploration of strongly correlated quantum materials made...
