The Implicit Matrix: Scaling Max-Cut with Paulis

Quantum Computing
VQE
Hamiltonian

We use the Max-Cut problem to demonstrate how to transition from a classical matrix formulation to a quantum operator without ever building the full dense matrix.

Exploring the Ansatz Zoo: Heuristics and the Parameter Gap

Quantum Computing
VQE
Ansatz

We cannot search the entire Hilbert space. We explore the n-local blueprint, why we prefer 2-local circuits, and use RealAmplitudes to find the answer with exponentially fewer parameters.
