Quantum circuit discovery agent · Qiskit + PyTorch

QUASAR

Full VQE optimization of every candidate circuit is far too expensive to search broadly.

What I built

A discovery loop where a PyTorch surrogate scores variational circuits (energy / trainability / confidence heads) and filters candidates before full VQE optimization (Qiskit StatevectorEstimator + scipy minimize), with barren-plateau detection and online surrogate retraining from the optimizer's results.
