TimeEvolution
(w, t)[source]¶ An operation for performing the transformation \(e^{-i\hat{H}t/\hbar}\) on a given state where \(\hat{H} = \sum_i \hbar \omega_i a_i^\dagger a_i\) defines a Hamiltonian of independent quantum harmonic oscillators
This operation can be used as part of a Strawberry Fields
Program
just like any other operation from theops
module.Example usage:
>>> modes = 2 >>> p = sf.Program(modes) >>> with p.context as q: ... sf.ops.Fock(1) | q[0] ... sf.ops.Interferometer(Ul.T) | q ... TimeEvolution(w, t) | q ... sf.ops.Interferometer(Ul) | q
- Parameters
w (array) – normal mode frequencies \(\omega\) in units of \(\mbox{cm}^{-1}\) that compose the Hamiltonian \(\hat{H} = \sum_i \hbar \omega_i a_i^\dagger a_i\)
t (float) – time in femtoseconds
