Special Issue Information

Dear Colleagues,

Fractional derivatives and integrals are nonlocal operators that can describe processes with non-locality in time and space. A novel and quickly developing area of quantum physics that investigates nonlocal quantum phenomena is the use of fractional calculus in quantum processes. It looks at nonlocal effects found in systems that are time-dependent or long-range at various scales. In recent years, there has been much interest in fractional quantum mechanics. The connection between fractional mechanics and other mathematical and physical disciplines may lead to new research directions, discoveries, and applications. This Special Issue's goal is to bring together scholars and researchers and provide them with a platform to share their innovative findings. The papers' primary areas of interest include theoretical, analytical, and numerical methods combined with state-of-the-art mathematical modeling, recent developments in fractional quantum mechanics, and physical applications in various branches of physics.

This Special Issue contains original research papers on current advances in fractional calculus, such as:

  • New developments in fractional quantum mechanics;
  • Mathematical aspects of fractional quantum mechanics;
  • Application of numerical methods to the problems of fractional quantum mechanics;
  • Relativistic fractional quantum mechanics;
  • Physical applications of fractional quantum mechanics, including (but not restricted to) Quantum Cosmology and Quantum Gravity, Particle Physics and Quantum Field Theory, Radiation and Laser physics, etc.

Quantum Fourier transform (QFT) transformation plays a very important role in the design of many quantum algorithms. Fractional Fourier transform (FRFT), as an extension of the Fourier transform, is particularly important due to the design of its quantum algorithm. In this paper, a new reformulation of the weighted fractional Fourier transform (WFRFT) is proposed in order to realize quantum FRFT; however, we found that this reformulation can be applied to other transformations, and therefore, this paper presents the weighted fractional Hartley transform (WFRHT). For the universality of application, we further propose a general weighted fractional-order transform (WFRT). When designing the quantum circuits, we realized the quantum WFRFT via QFT and quantum phase estimation (QPE). Moreover, after extending our design to the WFRHT, we were able to formulate the quantum WFRHT. Finally, in accordance with the research results, we designed the quantum circuit of the general WFRT, and subsequently proposed the quantum WFRT. The research in this paper has great value as a reference for the design and application of quantum algorithms. Full article
