Robust Quantum Gate Preparation in Open Environments
Luke S. Baker, Syed A. Shah, Anatoly Zlotnik +1
We develop an optimal control algorithm for robust quantum gate preparation in open environments with the state of the quantum system represented using the Lindblad master equation…
Harnessing Complexity: Nonlinear Optical Phenomena in L-Shapes, Nanocrescents, and Split-Ring Resonators
Michael R. Clark, Syed A. Shah, Andrei Piryatinski +1
We conduct systematic studies of the optical characteristics of plasmonic nanoparticles that exhibit C2v symmetry. We analyze three distinct geometric configurations: an L-type sha…
Interplay of gain and loss in arrays of nonlinear plasmonic nanoparticles: toward parametric downconversion and amplification
Syed A. Shah, Michael R. Clark, Joseph Zyss +2
With the help of a theoretical model and finite-difference-time-domain simulations based on the hydrodynamic-Maxwell model, we examine the effect of difference frequency generation…
Correlated noise enhances coherence and fidelity in coupled qubits
Eric R Bittner, Hao Li, Syad A. Shah +2
It is generally assumed that environmental noise arising from thermal fluctuations is detrimental to preserving coherence and entanglement in a quantum system. In the simplest sens…
QuDPy: A Python-Based Tool For Computing Ultrafast Non-linear Optical Responses
S. A. Shah, Hao Li, Eric R. Bittner +2
Nonlinear Optical Spectroscopy is a well-developed field with theoretical and experimental advances that have aided multiple fields including chemistry, biology and physics. Howeve…
The Optical Signatures of Stochastic Processes in Many-Body Exciton Scattering
Hao Li, S. A. Shah, Ajay Ram Srimath Kandada +3
We review our recent quantum stochastic model for spectroscopic lineshapes in the presence of a co-evolving and non-stationary background population of excitations. Starting from a…
Stochastic exciton-scattering theory of optical lineshapes: Renormalized many-body contributions
Hao Li, S. A. Shah, Eric R. Bittner +2
Spectral line-shapes provide a window into the local environment coupled to a quantum transition in the condensed phase. In this paper, we build upon a stochastic model to account…
Probing exciton/exciton interactions with entangled photons: theory
Eric R. Bittner, Hao Li, Andrei Piryatinski +2
Quantum entangled photons provide a sensitive probe of many-body interactions and offer an unique experimental portal for quantifying many-body correlations in a material system. I…
Photon entanglement entropy as a probe of many-body correlations and fluctuations
Hao Li, Andrei Piryatinski, Ajay Ram Srimath Kandada +2
Recent theoretical and experiments have explored the use of entangled photons as a spectroscopic probe of material systems. We develop here a theoretical description for entropy pr…
Probing dynamical symmetry breaking using quantum-entangled photons
Hao Li, Andrei Piryatinski, Jonathan Jerke +3
We present an input/output analysis of photon-correlation experiments whereby a quantum mechanically entangled bi-photon state interacts with a material sample placed in one arm of…
