There are lots of microscopic CPT tests ( https://arxiv.org/pdf/0801.0287 ), but it seems there is missing a real macroscopic one (?) - test if CPT analogue of a setting works as it should.

The diagram show such proposed test - this symmetry suggests existence of looking unknown effect e.g. for ring laser, with potentially lots of new applications (like quantum computing) - increase probability of directional deexcitation of target.

I am searching for access to one/collaboration to test its existence. Negative effect would be also interesting as suggesting macroscopic violation of CPT symmetry. Please contact me if interested.

Ring lasers allow for nearly unidirectional photon trajectories. Looking from perspective after applied CPT symmetry to the shown setting, photons would travel in the opposite direction - causing excitation of the target (lamp).

Going back from CPT to to the original perspective, the above means laser causes deexictation of the target. (lamp continuously excited in corresponding spectrum, increased probability of directional deexcitation in addition to standard isotropic radiation).

Just prepared separate paper about its application to improve photonic quantum computer (looking for collaboration):
