Locally Real States in the Elimination of Non-local Superposition and Entanglement

Locally real states of electromagnetic radiation derived from the underlying quantum mechanical formalism are shown to provide an alternative basis for definite polarized states of the widely accepted probabilistic interpretation. The locally real states traverse common loop configurations without invoking non-local superposition. Correlated photon pairs represented by the locally real states are consistent with the underlying quantum mechanical formalism independent of Bell's inequality and without invoking entanglement. Replacement of interdependent non-local probabilistic states with the locally real states yields independence of those states. A novel loop configuration provides differential testability of the representation of the locally real states relative to the probabilistic interpretation with the prediction of a unique polarization state.

A Questionable Fundamental Basis for Quantum Computing Advantage

The widely accepted basis for quantum computing advantage is derived from the entanglement and superposition properties of the probabilistic interpretation of the underlying quantum mechanical formalism which in turn is widely accepted based upon results of Bell experiments. That advantage is questioned here in view of a locally real interpretation that is not negated by Bell experiments and under which entanglement and superposition are excluded.

Macroscopic Violation of Duality Generated on a Laser Beam

It is shown theoretically and experimentally that passage of a laser beam through particular conventional Ronchi gratings prepares the beam in an altered state that violates quantum duality. The violation is characterized by a readily measured net transfer of energy between the prepared beam and an unmodified beam from a similar, independent laser. Notably, the experiment is conducted with the beams at macroscopic power levels where measurability of the duality-violating transfer is vastly improved over that of the discrete photon regime. These results are consistent with other recently reported experiments that have challenged the validity of the duality-related principle of complementarity.

Duality violation from a grating

Diffraction orders in the continuous wave regime generated by a Ronchi transmission grating in a standard threshold configuration are shown theoretically to violate quantum duality for a locally real representation. The phenomenon superficially resembles Rayleigh anomalies but is notably distinguished from those anomalies by a prediction of probability non-conservation. This prediction is experimentally tested with a 633 nm laser beam at normal incidence on gratings giving that threshold condition for the \pm 3rd order pair. Transient intersection of the Oth order with an independent 633 nm laser beam demonstrates a duality-violating probability non-conservation in good agreement with the theoretical prediction.

Experimental test for violation of duality on a photon beam

We test for evidence violating the duality invariant ratio of photon beam irradiance and wave intensity. Split beams from a 633 nm HeNe laser are intersected at a diffraction grating complementary to the resultant interference pattern. An output beam from the grating, depleted in irradiance relative to wave intensity from the perspective of local realism, is transiently intersected with a beam from an independent HeNe laser and measured irradiance is amplified by ~4% in conflict with quantum mechanics.

High Efficiency Interaction-free Measurement from Continuous Wave Multi-beam Interference

A new method for high efficiency interaction-free measurement is presented. Selective transmission of multiple beam interference is used to generate a continuous wave target beam with an irradiance level ~1% that of a reference beam. When the target beam is unobstructed by a potentially interposed object, the resultant measured interference visibility of 0.86 with the reference beam significantly exceeds the classically predicted irradiance-based visibility of 0.17 and provides a methodology for ~100% interaction-free measurement with a continuous wave beam.
