An introduction to of quantum-dot cellular automata (QCA) is presented. QCA is a transistorless nanoelectronic computation paradigm that addresses the issues of device and power density which are becoming increasingly important in the electronics industry. Scaling of CMOS is expected to come to an end in the next 10-15 years, with perhaps the most important… (More)

Quantum-dot Cellular Automata (QCA) is a computational paradigm that uses local physical coupling between nominally identical bistable building blocks (cells) assembled into arrays to perform binary logic functions. QCA offers low power dissipation and high integration density of functional elements. Depending upon the choice of local fields causing… (More)

Experimental studies are presented of a binary wire based on the quantum-dot cellular automata computational paradigm. The binary wire consists of capacitively coupled double-dot cells charged with single electrons. The polarization switch caused by an applied input signal in one cell leads to the change in polarization of the adjacent cell and so on down… (More)

We report the fabrication of, and demonstrate logic functionality in, networks of magnetically-coupled, nanometer-scale magnets performing binary computation in a magnetic quantum-dot cellular automata (MQCA) system. MQCA is an all-magnetic logic that offers low power dissipation and high integration density of functional elements.

An introduction to the operation of quantum-dot cellular automata is presented, along with recent experimental results. Quantum-dot cellular automata ͑QCA͒ is a transistorless computation paradigm that addresses the issues of device density and interconnection. The basic building blocks of the QCA architecture, such as AND, OR, and NOT are presented. The… (More)

We perform measurements on an AlGaAs/GaAs double-quantum-dot structure, where dots are separated by an opaque barrier and each dot conductance is measured independently and simultaneously. We measure the Coulomb blockade oscillations ͑CBOs͒ for each dot when the structure is configured for one and two dots. When configured as a single-dot device, we sweep… (More)

Synthesis of efficient DFT (Design for Testability) logic is of prime importance in robustly testable design of QCA based logic circuits. An ingenious universal QCA gate structure, Coupled Majority-Minority (CMVMIN) gate, realizes majority and minority functions simultaneously in its 2-outputs. This device enables area saving implementation of complex QCA… (More)

Quantum Cellular Automata (QCA) is an emerging nanotechnology and one of the top six technologies of the future. CMOS technology has a lot of limitations while scaling into a nano-level. QCA technology is a perfect replacement of CMOS technology with no such limitations. In this paper we have proposed one 2:1 multiplexer circuit having lowest complexity and… (More)

Quantum Cellular Automata is a promising nanotechnology that has been recognized as one of the top six emerging technology in future computers. We have developed a new methodology in design QCA 2:1 MUX having better area efficiency and less input to output delay. We have also shown that using this QCA 2:1 M UX as a unit higher M UX can also be designed. We… (More)

In past few years many efforts have been made on Quantum-dot cellular automata (QCA) because it seems a good candidate for implementing next generation computers. Other technologies use electricity voltage or current to represent the binary values. However, in QCA it represents with charge polarization. In this paper two inverters are proposed whose… (More)
