spheres.symplectic.upgrade_single_mode_operator(O, i, n_modes)

Upgrades a single mode real symplectic operator O to act on the i’th of n modes (where the latter are represented in terms of their first and second moments.)

Parameters

• O (np.array) – Single mode operator.

• i (int) – Which mode to act on.

• n_modes (int) – Of how many modes.

Returns

U – Upgraded operator.
