Three-dimensional quantum cellular automata adder

Abstract

The invention discloses a three-dimensional quantum cellular automata adder, which comprises seven quantum cellular automata connecting lines, a two-dimensional majority logic gate, a two-layer three-dimensional majority logic gate, a three-layer three--dimensional majority logic gate, a first three-dimensional phase inverter, a second three-dimensional phase inverter, a third three-dimensional phase inverter, a fourth three-dimensional phase inverter, a first two-dimensional phase inverter and a second two-dimensional phase inverter. Compared with a traditional two-dimensional quantum cellular automata adder, the three-dimensional quantum cellular automata adder provides an extra one-dimensional computation space, so that fewer cells are required, and meanwhile, the space and the power consumption of a circuit are drastically reduced. The three-dimensional quantum cellular automata adder is a novel quantum cellular automata adder which has the advantages of being low in three-dimensional power consumption and small in area.

Description

technical field [0001] The invention relates to the field of circuit design based on quantum cellular automata, in particular to a three-dimensional quantum cellular automata adder. Background technique [0002] Integrated circuits are undergoing a transition from the era of microelectronics to the era of nanoelectronics. As the feature size of complementary metal-oxide-semiconductor (CMOS) devices shrinks to less than 20 nanometers, CMOS technology will soon reach its physical limits. Since it is difficult for CMOS devices to solve the quantum effects caused by size reduction and the increasingly serious heat dissipation and power consumption problems, the development of integrated circuits based on CMOS technology will encounter bottlenecks, and these difficulties and problems are difficult to solve by improving existing processes and technology to solve it fundamentally. According to the International Semiconductor Technology Roadmap Report (ITRS), when the feature size...
