This document establishes publication priority for the concept of an optical Josephson junction based on resonant electromagnetic coupling of toroidal electron pairs through a thin barrier in a phosphorus-doped silicon cylinder.Within the Genesis-1 Ethon-Space framework, the electron is a relativistic toroidal EM structure in electromagnetic levitation around the nucleus. Its apparent polarity is a geometric projection varying as sin²θ, yielding four logical states derived from spin orientation and field dynamics. Quantum superposition emerges exclusively from the coupling of two toroidal electrons — not as an intrinsic particle property.The proposed device consists of a pnpn/npnp cylindrical silicon structure doped in concentric layers, sliced into thin wafers exposing all junctions to optical excitation. State switching is triggered by photons at frequency f₀. An integrated analog microcircuit stabilizes and retains the quantum state as non-volatile memory. Error correction is inherent through majority-vote coupling between neighboring electron pairs.

We propose to create pairs of semifluxons starting from a flat-phase state in long, optical 0-$\ensuremath{\pi}$-0 Josephson junctions formed with internal electronic states of atomic Bose-Einstein condensates. In this optical system, we can dynamically tune the length a of the $\ensuremath{\pi}$ junction, the detuning $\ensuremath{\delta}$ of the optical transition, or the strength ${\ensuremath{\Omega}}_{0}$ of the laser coupling to induce transitions from the flat-phase state to such a semifluxon-pair state. Similarly as in superconducting 0-$\ensuremath{\pi}$-0 junctions, there are two, energetically degenerate semifluxon-pair states. A linear mean-field model with two internal electronic states explains this degeneracy and shows the distinct static field configuration in a phase diagram of the junction parameters. This optical system offers the possibility to dynamically create a coherent superposition of the distinct semifluxon-pair states and observe macroscopic quantum oscillation.
The Josephson junction is a device and constructed by separating two superconductors with an insulating barrier, which is thin enough so that super-electrons or Cooper pairs, composed of two electrons with opposite momenta and spins, formed by the electron-phonon interaction, and described as probability waves, can quantummechanically tunnel through the barrier and cause superposition and interferences. Due to the quantum e↵ect, a Josephson junction can generate and sustain an indefinitely long direct electric current or potential di↵erence, which becomes alternating one when an external voltage is applied. This paper investigates the Josephson pulse including its generation, property, and control. The results obtained from this study indicate that perturbations of the superconductors can generate strong superconducting pulses in the Josephson junction. The electric potential and field in the barrier oscillate when the two superconductors have di↵erent physical properties including the number densities of super-electrons, the phases of superconductors, and their rates of variations. The oscillations can be harmonic, combined, and purely pulse-like. The strength of the pulse increases with the di↵erences in the rates of densities and phases between the two superconductors. The pulse can be stronger in strength and narrower in width when one superconductor has lower density but higher rates of density and phase than another superconductor. Light or electromagnetic waves can perturb the superconductivities of superconductors and hence can be applied to control the pulses of Josephson junctions.
Josephson junctions are essential ingredients in the superconducting circuits used in many existing quantum technologies. Additionally, ultracold atomic quantum gases have also become essential platforms to study superfluidity. Here, we explore the analogy between superconductivity and superfluidity to present an intriguing effect caused by a thin finite barrier in a quasi-one-dimensional toroidal spinor Bose–Einstein condensate (BEC). In this system, the atomic current density flowing through the edges of the barrier oscillates, such as the electrical current through a Josephson junction in a superconductor, but in our case, there is no current circulation through the barrier. We also show how the nontrivial broken-symmetry states of spinor BECs change the structure of this Josephson-like current, creating the possibility to probe the spinor symmetry, solely using measurements of this superfluid current.
de Broglie wave interferometers have been constructed, successfully utilizing extended superconducting links of tin to couple coherently the quantum phases of two Josephson junctions. The current transmitted by these devices was periodic in the enclosed flux (periodicity (.9 ± .3) h/2e) demonstrating unambiguously coherence of the superconducting order parameter over 1.33 meters. We may define a Josephson junction as one for which the quantum mechanical coupling energy is insufficient to overcome the disruptive effects of noise. Consequently, the relative phase of the coupled superconductors is not stabilized and the zero Josephson current fluctuates, (bandwidth ~ 2eVnoise/h) averaging to zero. Two such junctions have been coupled to an electromagnetic cavity formed by the superconducting arms of a quantum interferometer (junction separation 1. 33 meters). With an applied steady voltage such that the Josephson current excites a normal mode of the cavity, a coherent radiation field is built up. This coherent radiation feeds back to the junctions forcing time coherence on the phase precession, resulting in a dynamic stabilization of the junctions. Under these conditions a series of constant voltage has been observed in the I-V characteristic of one interferometer. The Josephson frequency associated with these steps is shown to be characteristic of the electromagnetic resonant modes of the cavity. Frequency modulation analysis, combined with a detailed analysis of the cavity-junction combination, predicts such maxima in the tunneling of pairs when a selection rule, (m + n) even, is obeyed. Here m/2 is the number of flux quanta (h/2e) linking the interferometer and n is the order of the cavity resonance excited. Experimental confirmation of the detailed predictions of the analysis is presented.
Abstract : The purpose of this research program was to develop a device architecture that is capable of coherently coupling two silicon spin qubits via the electromagnetic field of superconducting resonator. Single Electron spins can be efficiently coupled using the exchange interaction, but the strength of exchange falls of very quickly as a function of the distance separating the two electron spins. Cavity based coupling schemes have recently emerged as a robust tool for coupling superconducting quantum bits. The main goal of this research program was to make the first steps toward combing elements of the superconducting and semiconductor qubit architectures.
The Genesis-1 framework postulates that space is a structured electromagnetic medium (Ethon-Space) composed of Ethons organized into prime-number fractal structures, with measurable properties ε₀, μ₀, c, Z₀. This document introduces the structural tension filament — a real geometric object produced by any fracture of a coherent Ethon fractal structure. It is a persistent longitudinal deformation of ε₀ along a structural line, whose joint state at both endpoints is defined instantaneously without signal propagation. This mechanism provides a causal and geometric explanation for quantum non-locality, consistent with Bell's inequalities. Applications are developed in particle physics (electron-positron pair, photon polarization), cosmology (physical origin of the cosmological constant, cosmic web), and quantum computing (decoherence as extrinsic perturbation). Falsifiable predictions are provided. Bilingual document: English / French.
