محاسبات کوانتومی یک روش جدید و کارآمد در سرعت دادن به محاسبات با استفاده از پدیده های مهمی از قبیل برهم نهی1 ، تداخل2 ، عدم موجبیت3 ، ناجایگزیدگی4 و تکثیرناپذیری5 ارائه می کند. و الگوریتم های کوانتومی ابزار کار برای این نوع محاسبات می باشند که با پیدایش محاسبات کوانتومی به عنوان زیر شاخه آن مورد توجه قرار گرفته اند که در تبدیل زمان محاسبات از نوع نمائی به چند جمله ای دارای اهمیت فراوان در محاسب...

Quantum dialogue is a type of quantum communication in which users can simultaneously send messages to each other. The earliest instances of quantum dialogue protocols faced security problems such as information leakage and were vulnerable to intercept and resend attacks. Therefore, several protocols have been presented that try to solve these defects. Despite these improvements, the quantum di...

We construct  a noncommutative analog of additive functional equations on discrete quantum semigroups and show that this noncommutative functional equation has Hyers-Ulam stability on amenable discrete quantum semigroups. The discrete quantum semigroups that we consider in this paper are in the sense of van Daele, and the amenability is in the sense of Bèdos-Murphy-Tuset. Our main result genera...

  The quantum dynamics of a charged particle in an infinite chain of single-state quantum wells, in tight-binding approximation and under the action of an arbitrary time-dependent external field is investigated. The connection between the Hamiltonian description of this model and the Hamiltonian of a discrete-charge mesoscopic quantum circuit is elucidated. Based on this connection, the persist...

There are many claims that quantum mechanics plays a key role in the origin and/or operation of biological organisms. The mechanism of the meiosis, mitosis and gametes life cycle from the view-point of quantum for human has been represented. The quantum gates have been used to simulate these processes for the first time. The reason of several hundred sperms has been explained in the male too

In this article we consider the resistance of a quantum LC circuit as a heat bath. The heat bath can be modeled by a collection of quantum harmonic oscillators with a continuum of frequencies. By using the minimal coupling method between the circuit and the field describing the environment, the process of energy dissipation and probability transitions between the energy levels of the quantum c...

A comprehensive study of Schottky barrier MOSFET (SBMOSFET) scaling issue is performed to determine the role of wafer orientation and structural parameters on the performance of this device within Non-equilibrium Green's Function formalism. Quantum confinement increases the effective Schottky barrier height (SBH). (100) orientation provides lower effective Schottky barrier height in compa...
