Abstract The urbanization rate of Nanjing has increased in the past 55 years. Its
development process can be roughly divided into the reverse urbanization phase,
the stagnant development phase, the recovery development phase, the steady
development phase, and the accelerated development phase. The area of cultivated
land has a decreasing trend at each stage. In 1971 and beyond, urbanization
development had a significant negative effect on the area of cultivated land, and
the coordination between the two was not high and there was a downward trend. More >

Abstract We want in this article to show the usefulness of Quantum Turing
Machine (QTM) in a high-level didactic context as well as in theoretical studies.
We use QTM to show its equivalence with quantum circuit model for Deutsch and
Deutsch-Jozsa algorithms. Further we introduce a strategy of translation from
Quantum Circuit to Quantum Turing models by these examples. Moreover we
illustrate some features of Quantum Computing such as superposition from a QTM
point of view and starting with few simple examples very known in Quantum
Circuit form. More >

Abstract An interpretation of the entangled states is considered. Two-photon
states of photon A on path a and photon B on path b with polarizations H, V are
constructed. Two synchronized photons, 1 and 2, can take the paths a and b, with
equal probability 50%. In the bases a, b and H, V, the states of the photons form
the product states. In the basis 1, 2, the states of the photons form the entangled
state. The states of the photons in the bases 1, 2; a, b; H, V are inseparable. The
correlation of the photons due to the… More >

Abstract To solve the problem of hiding quantum information in simplified
subsystems, Modi et al. [1] introduced the concept of quantum masking.
Quantum masking is the encoding of quantum information by composite
quantum states in such a way that the quantum information is hidden to the
subsystem and spreads to the correlation of the composite systems. The concept
of quantum masking was developed along with a new quantum impossibility
theorem, the quantum no-masking theorem. The question of whether a quantum
state can be masked has been studied by many people from the perspective of the
types of quantum states, the number… More >
