class lightworks.State(state: list[int])

Custom data type to store information about a quantum state, as well as allowing a number of operations to act on the state.

Parameters:

state (list) – The fock basis state to use with the class, this should be a list of photon numbers per mode.

merge(merge_state: State) → State

Combine two states, summing the number of photons per mode.

property n_modes: int

The total number of modes in the state.

property n_photons: int

Returns the number of photons in a State.

property s: list[int]

Returns a copy of the contents of the state as a list.
