DualUnitary

DualUnitary(real J, integer i, integer j) -> OperatorParam<real>​

Returns a spin-1/2 dual unitary operator: exp⁡(i(π4X(i)X(j)+π4Y(i)Y(j)+JzZ(i)Z(j)))\exp(i(\frac{\pi}{4} X(i) X(j) + \frac{\pi}{4} Y(i) Y(j) + J_z Z(i) Z(j))) where i,ji, j are the site indices.

Parameters​

  • J: The Jz constant parameter.
  • i: Site index i.
  • j: Site index j.

Example​

var dual_u = DualUnitary(0.25, 0, 1)  // Dual unitary with Jz=0.25
