Programmable Dissipation via Partial Quantum Error Correction
Sameer Dambal, Michael AD Taylor, Yu Zhang
Noise is typically treated as the adversary of quantum information processing. For open quantum dynamics, however, dissipation is part of the target physics, creating a tension wit…
Thermalization Regimes in a Chaotic Tavis-Cummings Model
Sameer Dambal, Eric R. Bittner
This work investigates the emergent thermalization regimes in a chaotic Tavis-Cummings (TC) model and their implications in quantum spectroscopy. While the TC model is a cornerston…
Scattering theory of frequency-entangled biphoton states facilitated by cavity polaritons
Andrei Piryatinski, Nishaant Jacobus, Sameer Dambal +3
The use of quantum light to probe exciton properties in semiconductor and molecular nanostructures typically occurs in the low-intensity regime. A substantial enhancement of excito…
Noise-Induced Thermalization in Quantum Systems
Sameer Dambal, Yu Zhang, Eric R Bittner +1
In the current Noisy Intermediate-Scale Quantum era, noise is widely regarded as the primary obstacle to achieving fault-tolerant quantum computation. However, certain stages of th…
Harnessing Intrinsic Noise for Quantum Simulation of Open Quantum Systems
Sameer Dambal, Akira Sone, Yu Zhang
Simulating open quantum systems on quantum computers presents a fundamental challenge: open quantum dynamics are intrinsically nonunitary, whereas quantum computers operate through…
Lyapunov Dynamics in Entangled Biphoton Spectroscopy
Sameer Dambal, Ajay Ram Srimath Kandada, Eric R. Bittner
We develop a Lyapunov-based framework to model the evolution of entangled biphotons interacting with cavity and material modes. Using Gaussian-preserving dynamics and Møller opera…
