Abstract Born’s rule is key to understanding quantum mechanics based on the probability amplitude for the measurement process of a physical quantity. Based on a typical particle nature of a photon, the quantum feature of photon bunching on a beam splitter between two output photons can be explained by Born’s rule even without clear definition of the relative phase between two input photons. Unlike conventional understanding on this matter, known as the Hong-Ou-Mandel effect, here, we present a new interpretation based on the wave nature of a photon, where the quantum feature of photon bunching is explained through phase basis superposition of the beam splitter. A Mach-Zehnder interferometer is additionally presented to support the correctness of the presented method. As a result, our limited understanding of the quantum feature is deepened via phase basis superposition regarding the destructive quantum interference. Thus, the so-called ‘mysterious’ quantum feature is now clarified by both the definite phase relationship between paired photons and a new term of the phase basis superposition of an optical system.

AbstractA novel method of macroscopically entangled light-pair generation is presented for a quantum laser using randomness-based deterministic phase control of coherent light in a coupled Mach–Zehnder interferometer (MZI). Unlike the particle nature-based quantum correlation in conventional quantum mechanics, the wave nature of photons is applied for collective phase control of coherent fields, resulting in a deterministically controllable nonclassical phenomenon. For the proof of principle, the entanglement between output light fields from a coupled MZI is examined using the Hong-Ou-Mandel-type anticorrelation technique, where the anticorrelation is a direct evidence of the nonclassical features in an interferometric scheme. For the generation of random phase bases between two bipartite input coherent fields, a deterministic control of opposite frequency shifts results in phase sensitive anticorrelation, which is a macroscopic quantum feature.

Abstract Recently, a new interpretation of quantum mechanics has been developed for the wave nature of a photon, where determinacy in quantum correlations becomes an inherent property without the violation of quantum mechanics. Here, we experimentally demonstrate a direct proof of the wave natures of quantum correlation for the so-called coherence de Broglie waves (CBWs) using sub-Poisson distributed coherent photon pairs obtained from an attenuated laser. The observed experimental data coincides with the analytic solutions and the numerical calculations. Thus, the CBWs pave a road toward deterministic and macroscopic quantum technologies for such as quantum metrology, quantum sensing, and even quantum communications, that are otherwise heavily limited due to the microscopic non-determinacy of the particle nature-based quantum mechanics.

The Relationship

In the last decades, the concept of cultural landscape, in its physical and social dimension, has been stoked by the contribution of a new interpretation of “technology,” understood as an innovative approach in the definition of new relationships between information, sustainability, and public space. It is a perspective that follows the changing cultural references of urban society, wondering which is the relationship between embodiment and location, between technological innovation and urban structure and how the digital and information revolution could influence and define the characteristics of urban aesthetics in the contemporary city. This chapter offers a key for reading these topics, starting from the analysis of the grid city's ontological space, its image between morphology and technology, between streets/buildings and infrastructure/landscapes, and finally, defining new ethical and dialogical interpretative approaches on sustainability and urban development, trying to find out the potentialities of the grid cities as complex public space systems.

The Americans With Disabilities Act Amendments Act of 2008 expanded the legal definition of disability to establish broader coverage for individuals with disabilities, including college students, than the definition in the Americans With Disabilities Act of 1990. The new interpretation of the definition of disability shifted the main purpose of documentation from proving eligibility for services as a person with a disability to determining appropriate academic accommodations. This change in the law, and subsequent Department of Justice regulations, enhances the importance of documentation from a student’s secondary education experience that may provide relevant information concerning functional limitations and the need for academic accommodations. This article provides practical guidance to high school professional staff in preparing disability documentation for students’ transition to college.

True Values

Traditionally the production quality of components is described by “acceptable quality levels” (AQL). Agreements, referring to this principle, determine the acceptance or refusal of batches that have been sample tested. An acceptable quality of level is interpreted as a tolerated limit. In reality true values of quality must be better. An AQL value cannot define a real quality level. Furthermore, increasing requirements for component quality lead to low figures for the permissible amount of faulty devices in batches, and the method of sample testing becomes insufficient.For these reasons it seems to be of major importance to establish a better standard for the definition of quality. The application oriented description of quality data offers a possible solution. A good exchange of experience between supplier and user, based on a close and quality loop, is necessary.For contractual purposes AQL values remain important, but their meaning needs a new interpretation.

Abstract Inspired by using the wave nature of electrons for electron quantum optics, we propose a new type of electron quantum interference logic device (eQILD), where an electron wave is coherently injected into a two-dimensional wave guide and controlled via two gates. Interference effects lead to different current levels in output channels and are utilized for classical logic gates. eQILDs can be reconfigured and support parallelism and multi-valued logic. The operating principle as well as realizations of a logic NAND and NOR gate is shown by means of dynamic quantum Wigner and classical simulations considering coherent/ballistic transport. Contrary to other advanced information processing approaches no magnetic or photonic mechanisms are required. The eQILD is inherently compatible with conventional integrated circuits and thus provides an attractive alternative towards advanced low-power information processing devices with the performance only limited by the single-electron source frequency, i.e., in the GHz regime.

International audience In a recent paper, Duane, Garsia, and Zabrocki introduced a new statistic, "ndinv'', on a family of parking functions. The definition was guided by a recursion satisfied by the polynomial $\langle\Delta_{h_m}C_p1C_p2...C_{pk}1,e_n\rangle$, for $\Delta_{h_m}$ a Macdonald eigenoperator, $C_{p_i}$ a modified Hall-Littlewood operator and $(p_1,p_2,\dots ,p_k)$ a composition of n. Using their new statistics, they are able to give a new interpretation for the polynomial $\langle\nabla e_n, h_j h_n-j\rangle$ as a q,t numerator of parking functions by area and ndinv. We recall that in the shuffle conjecture, parking functions are q,t enumerated by area and diagonal inversion number (dinv). Since their definition is recursive, they pose the problem of obtaining a non recursive definition. We solved this problem by giving an explicit formula for ndinv similar to the classical definition of dinv. In this paper, we describe the work we did to construct this formula and to prove that the resulting ndinv is the same as the one recursively defined by Duane, Garsia, and Zabrocki. Dans un travail récent Duane, Garsia et Zabrocki ont introduit une nouvelle statistique, "ndinv'' pour une famille de Fonctions Parking. Ce "ndinv" découle d'une récurrence satisfaite par le polynôme $\langle\Delta_{h_m}C_p1C_p2...C_{pk}1,e_n\rangle$, oú $\Delta_{h_m}$ est un opérateur linéaire avec fonctions propres les polynômes de Macdonald, les $C_{p_i}$ sont des opérateurs de Hall-Littlewood modifiés et $(p_1,p_2,\dots ,p_n)$ est un vecteur à composantes entières positives. Par moyen de cette statistique, ils ont réussi à donner une nouvelle interprétation combinatoire au polynôme $\langle\nabla e_n, h_j h_n-j\rangle$ on remplaçant "dinv'" par "ndinv". Rappelons nous que la conjecture "Shuffle"' exprime ce même polynôme comme somme pondérée de Fonctions Parking avec poids t à la "aire'" est q au "dinv". Puisque il donnent une définition récursive du "ndinv" il posent le problème de l'obtenir d'une façon directe. On rèsout se problème en donnant une formule explicite qui permet de calculer directement le "ndinv" à la manière de la formule classique du "dinv". Dans cet article on décrit le travail qu'on a fait pour construire cette formule et on démontre que nôtre formule donne le même "ndinv" récursivement construit par Duane, Garsia et Zabrocki.
