Although experimental evidence suggests the influence of quantum effects in living organisms, one of the most critical problems in quantum biology is the explanation of how those effects that take place in a microscopic level can manifest in the macroscopic world of living beings. At present, quantum decoherence associated with the wave function collapse is one of the most accepted mechanisms e...

A method of quantization of classical soliton cellular automata (QSCA) is put forward that provides a description of their time evolution operator by means of quantum circuits that involve quantum gates from which the associated Hamiltonian describing a quantum chain model is constructed. The intrinsic parallelism of QSCA, a phenomenon first known from quantum computers, is also emphasized.

Ordered quantum dot molecules are grown by a modified MBE growth using thin-capping and regrowth processes. This technique yields QDs which are uniform and aligned along [11̄0] directions. This paper presents an attempt to group 4-5 dots per each quantum dot molecule, in order to form a physical structure that can function as quantum cellular automata, giving rise to the possibility of developin...

In this article, we try to model the effect of changes in threshold voltage two positive inputs negative ones using nanotechnology based on Quantum Dot Cellular automata (QCA). order do so, voter a Majority cell has been modified resulting amplifying upper and lower cells. Besides Brain-inspired approach can be used design very fast function with QCA.

noise removal operation is commonly applied as pre-processing step before subsequent image processing tasks due to the occurrence of noise during acquisition or transmission process. a common problem in imaging systems by using cmos or ccd sensors is appearance of  the salt and pepper noise. this paper presents cellular automata (ca) framework for noise removal of distorted image by the salt an...

Quantum cellular automata (QCA) consist in an array of identical finite-dimensional quantum systems. The whole array evolves in discrete time steps by iterating a unitary operator G. Moreover this global evolution G is shift-invariant (acts everywhere the same), and local (information can only be transmitted at a bounded speed). Whilst this axiomatic definition is clearly the natural ‘quantizat...

We show that a direct transposition of a generic IC architecture on a QCA technology is rendered inefficient by characteristics intrinsic to the model. This analysis constitutes the motivation for an application-specific architectural approach based on regular blocks proposed further in the paper. The basic architectural model is specified and a design methodology allowing the mapping of regula...

We present an experimental demonstration of a fanout gate for quantum-dot cellular automata (QCA), where a signal applied to a single input cell is amplified by that cell and sent to two output cells. Each cell is a single-electron latch composed of three metal dots, which are connected in series by tunnel junctions. Binary information is represented by an excess electron localized to one of th...
