<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="font-size:14.0pt">My answer is a strong “No”.</span><o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="font-size:14.0pt">I just presented this paper at the OSA Annual meeting last week, held at Washington, DC. It was well accepted by many.</span><o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="font-size:14.0pt">It is only an 11-slide presentation. However, it experimentally demonstrates that, for Superposition Effect to emerge, we must have the simultaneous
presence of two physical signals carrying two physically different phase information incident on the opposite sides of the beam-combiner of a two-beam Mach-Zehnder interferometer. The superposition effect emerges as purely a classical effect facilitated by
the dielectric boundary of the beam combiner (classical light-matter interaction; no QM). The energies in the two superposed beams can have any value, no lower limit like “h-nu”. Thus, single photon interference is causally and physically an untenable logic,
in my view point.</span><o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="font-size:14.0pt"> </span><o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="font-size:14.0pt">The experiment also underscores that the postulate of the “Wave-particle duality”, is completely unnecessary for EM waves. In fact, the Copenhagen
Interpretation becomes more logical and causal without this postulate. The QM formulation is essentially correct. We do not need to degrade it by imposing non-causal postulates.</span><o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="font-size:14.0pt">In the past, I have also proposed an experiment to validate that for “particle interference”, we also need pairs of out-of-phase particles to nullify
the stimulation of the detector molecule to generate “dark fringes”.</span><o:p></o:p></p>
