RotX

RotX(real phi, integer site) -> OperatorParam<real>​

Returns a spin-1/2 RotX(ϕ)=exp⁡(−iϕX/2)(\phi) = \exp(-i\phi X/2) rotation operator around the X-axis.

Parameters​

  • phi: The rotation angle.
  • site: The site index where the operator acts.

Example​

var rx_half = RotX(1.5708, 0)  // π/2 rotation on site 0
