- This decomposition allows for lower depth photonic circuits in physical devices by applying two
- independent phase shifts in parallel inside each Mach-Zehnder interferometer.
- ``rectangular_compact`` reduces the layers of phase shifters from 2N+1 to N+2
- for an N mode interferometer when compared to e.g. ``rectangular_MZ``.
