WebOur proposal treats the full Hamiltonian of the 1Σ+ molecule NaCs, utilizing a pair of nuclear spin states as storage qubits. A third rotationally excited state with rotation-hyperfine coupling enables switchable electric dipolar exchange interactions between two molecules to generate an iSWAP gate. All three states are insensitive to external ... Webdipolar forces are weaker than the exchange interaction [24]; i.e. g ~ 1. All quantities are given in units of the lattice spacing a. The symmetry of the hamiltonian suggests decomposing the spin operator S(q) into one longitudinal and two transverse components with respect to the wavevector q; i.e. 5(q) =Sl~(q)4+ST1_(q)I’(4)+ST2(q)i2(4),
WebWe implement an iterative quantum state transfer exploiting the natural dipolar couplings in a spin chain of a liquid crystal NMR system. During each iteration a finite part of the amplitude of the state is transferred…
