Simulability transitions in continuous-time dynamics of local open quantum systems
Rahul Trivedi, J. Ignacio Cirac
We analyze the complexity of classically simulating continuous-time dynamics of locally interacting quantum spin systems with a constant rate of entanglement breaking noise. We pro…
Superradiance in dynamically modulated Tavis-Cumming model with spectral disorder
Alexander D. White, Rahul Trivedi, Kalyan Narayanan +1
Superradiance is the enhanced emission of photons from quantum emitters collectively coupling to the same optical mode. However, disorder in the resonant frequencies of the quantum…
Convergence guarantees for discrete mode approximations to non-Markovian quantum baths
Rahul Trivedi, Daniel Malz, J. Ignacio Cirac
Non-Markovian effects are important in modeling the behavior of open quantum systems arising in solid-state physics, quantum optics as well as in study of biological and chemical s…
Quantum algorithms for powering stable Hermitian matrices
Guillermo González, Rahul Trivedi, J. Ignacio Cirac
Matrix powering is a fundamental computational primitive in linear algebra. It has widespread applications in scientific computing and engineering, and underlies the solution of ti…
