PauLie: Fast Classification of Pauli Dynamical Lie Algebras
Oxana Shaya, Konstantin Golovkin, Mainak Roy +1
The dynamical Lie algebra (DLA) governs the controllability, expressibility, and simulation complexity of a quantum system. Explicitly computing it has been a major computational b…

Quantum-Gravitational Backreaction in the BTZ Background from Curved Momentum Space
Partha Nandi, Mainak Roy, Langa Horoto +2
We explore how quantum properties of spacetime, specifically the curvature of momentum space, can backreact on classical gravity within a tractable semiclassical (2+1)-dimensional…

Simulating open quantum systems using noise models and NISQ devices with error mitigation
Mainak Roy, Jessica John Britto, Ryan Hill +1
In this work, we present simulations of two Open Quantum System models, Collisional and Markovian Reservoir, with noise simulations, the IBM devices ($\textit{ibm_kyoto}$, $\textit…
