Basis Adaptive Algorithm for Quantum Many-Body Systems on Quantum Computers
Anutosh Biswas, Sayan Ghosh, Ritajit Majumdar +3
The paper proposes a Basis Adaptive algorithm that combines quantum sampling with classical diagonalization to compute ground‑state properties of correlated many‑body systems while…
Poisson-shot-noise hybrid machines: efficiency and quasistatic divergence
Rita Majumdar, Costantino Di Bello, Ralf Metzler +2
We study stochastic models of a microscopic active heat engine, comprised of an overdamped Brownian particle trapped in a harmonic potential, and in simultaneous contact with therm…
Observation of Robust and Coherent Non-Abelian Hadron Dynamics on Noisy Quantum Processors
Fran IlÄiÄ, Ritajit Majumdar, Emil Mathew +3
The real-time evolution of strongly interacting matter remains a frontier of fundamental physics, as classical simulations are hampered by exponential Hilbert space growth and rapi…
Noise-aware selection of circuit cutting strategies under hardware noise non-uniformity
Debarthi Pal, Ritajit Majumdar, Padmanabha Venkatagiri Seshadri +2
Noise in contemporary quantum hardware is highly non-uniform across qubits and couplers, giving rise to localized low-noise "islands" within otherwise noisy device topologies. As q…
Low overhead circuit cutting with operator backpropagation
Debarthi Pal, Ritajit Majumdar
Current quantum computers suffer from noise due to lack of error correction. Several techniques to mitigate the effect of noise have been studied, in particular to extract the expe…
Lightweight Targeted Estimation of Layout Noise in a Quantum Computer using Quality Indicator Circuits
Shikhar Srivastava, Ritajit Majumdar, Padmanabha Venkatagiri Seshadri +2
Minimizing noise is essential for reliably executing quantum circuits on the current generation of hardware. The mapping of an abstract quantum circuit to the physical layout of th…
