Transformer-Accelerated Variational Quantum Eigensolvers via Parameter Warm-Starting

Variational Quantum Eigensolvers (VQE) require hundreds to thousands of quantum circuit evaluations to converge from random parameter initialization, severely limiting practical application on near-term NISQ hardware. We investigate whether a 13,156-parameter transformer encoder...

Reproduction of Zero Noise Extrapolation: Temme, Bravyi & Gambetta (PRL 119, 180509, 2017)

Full reproduction of the Zero Noise Extrapolation (ZNE) method from Temme, Bravyi & Gambetta (Physical Review Letters 119, 180509, 2017). Implemented from scratch using NumPy density matrix simulation with depolarizing noise channels. Covers: (1) gate folding for noise amplificat...
