For electronic or microfluidic chip we can actively influence them from both directions - why couldn't we do it also for some quantum computer technologies e.g. photonic?
For example using ring laser as in diagram - unidirectional photon trajectories, creating positive radiation pressure in one direction - used as state preparation: influencing initial states in front of photonic chip.
In CPT symmetry perspective physics should work the same due to CPT theorem: photon trajectories would be reversed, what means positive radiation pressure into the back of CPT(photonic chip) - exactly as state preparation, but influencing CPT(initial state) - what is the final state in <Phi_final | quantum gates | Phi_initial> symmetric formulation popular e.g. in scattering theory.
If possible, we could get postBQP replacing postselection with applied physical constraints - could e.g. attack NP problems.

Comment: while naively radiation pressure is only positive, it is a vector ( https://en.wikipedia.org/wiki/Radia...sure_from_momentum_of_an_electromagnetic_wave ) - can be toward a surface (positive), or outward (negative).
