How to repair the problem of infinite energy of electric field of point electron?

Assuming point electron with ~1/r^2 electric field, energy of this field alone would be infinite. In contrast, we know that this energy is bounded by 511keVs, released while annihilation. We...

Quantum computers have unitary-symmetric evolution, but asymmetric treatment of boundary conditions - could we add missing CPT(state preparation)?

Stimulated emission-abosrption are CPT analogs, one allows for state preparation for photonic quantum computers - couldn't we use the second for CPT analogue of state preparation? If so, e.g. by...
