N-slit quantum interferometers in the nanometer domain

N-slit quantum interferometry in the Planck domain

“…The𝑁-slit interferograms obtained at the Planck scale are similar in form to those calculated under 𝛾-ray radiation [14] and to those experimentally verified in the visible domain under illumination via ensembles of indistinguishable photons [13,14,27].…”

“…𝑁-slit coherent interferometer configurations have been recently examined in physical dimensions in the nanometer domain whilst considering 𝛾-ray illumination at 𝜆 ≈ 1×10 −13 m [14]. This is in line with recent efforts in the study of quantum effects, such as entanglement, at high energies [15].…”

“…The interferogram propagates through the intra interferometric space and is detected, or measured, at the interferometric plane 𝑑. Detailed experimental descriptions are given in [13,14,18].…”

“…The work presented here is an extension of the 𝛾-ray illumination work [14] to the Planck The introduction of an intermediate interferometric plane in the 𝐷 ⟨𝑑 | 𝑗 ⟩ space has been described and explained in [13,14]. Again, here we apply the cascade method [14] to quantify the effect of introducing a diffractive element within the 𝐷 ⟨𝑑 | 𝑗 ⟩ path, as outlined in Fig. 2, where a diffractive element is inserted in the intra interferometric path 𝐷 ⟨𝑑 | 𝑗 ⟩ at Δ𝐷 ⟨𝑑 | 𝑗 ⟩ from 𝑑 and at Δ𝑑 from the center of the interferometric plane.…”

“…More recently [16], the suggestion was made to extend this interferometric approach to the confines of the Planck length regime [17]. In this regard, the same theoretical-numerical methodology of [14] is applied to photon illumination at wavelengths in the Planck-length domain so that 𝜆 = 𝑙 𝑝 = 1.616255 × 10 −35 m.…”
