Semi-analytic PMP approach for time-optimal Rydberg-blockaded multi-qubit control, including a classical particle-in-quartic-potential analogy for two-qubit normal extremals.
A new optimal-control scheme achieves high-fidelity two-qubit iSWAP gates for Rydberg atoms at separations exceeding 20 micrometers through coherent excitation-exchange-deexcitation dynamics.
In the variable-range Ising model, correlations are algebraic up to distance Z then exponential, while entanglement scales as Z^{-γ} at criticality independent of partition size and α>1.
