Quantum cellular automata (QCA) is an innovative approach that incorporates quantum entities in classical computation processes. Binary information is encoded in different charge states of the QCA cells and transmitted by the inter-cell Coulomb interaction. Despite the promise of QCA, however, it remains a challenge to identify suitable building blocks for the construction of QCA. Graphene has ...

Quantum Cellular Automata (QCA) present one of the many emerging computational nanotechnology paradigms. It uses the arrangements of individual electrons, instead of currents and voltages, to encode binary information. Note a QCA cell consists of four quantum dots located at the corners of a square. This tutorial paper provides an introductory material on the design and testing of combinational...

We will prove the existence of a universal quantum cellular automaton. Such qca are defined as the quantum-mechanical pendant of classical one-dimensional cellular automata. As is the case with quantum Turing machines, the well-formedness restriction plays an important role. It will be shown that every proper qca obeys a local constraint which is comparable with the ‘inverse neighborhood’ of cl...

Among emerging technologies, Quantum-dot Cellular Automata (QCA) is an attractive alternative for transistor based technologies. In this paper, novel efficient Quantum-dot Cellular Automata (QCA) devices are proposed that provide 3-input and 4-input AND & OR gates. These gates have simple structure and are efficient in term of cell counts, complexity and latency. These components are suitable f...

The Quantum Cellular Automata (QCA) majority block gate, while more robust than the simple or classic version of the gate, is still affected by lithographic manufacturing errors that affect the polarization of each individual QCA and the block circuit. Analysis and correction of these errors has been done using Bayesian, Markovian, or neural network methodologies. The problem with learning an o...

The CMOS transistor has reached the molecular level due to the continuous miniaturization. With devices that small, problems in manufacturing and functionality appear. Since quantum effects become prevalent, technology that would take advantage of them is desirable. One of the proposed novel technologies is the quantum-dot cellular automaton (QCA) [1, 2]. Its basic building block is a QCA cell ...
