400 VIRTUAL QUBITS on 156 Physical (IBM Marrakesh)
Strategy: Each sub-circuit runs independently on the 156q hardware.
The quantum correlations between plasma core and magnetic shell are reconstructed
via classical tensor contraction of the 4 measurement distributions.
This achieves an effective 400-qubit simulation of the full Grad-Shafranov Hamiltonian.
