Problems solved by technology

On the one hand, atomic-scale components no longer obey Ohm's law, and quantum effects will occur immediately, and the behavior of circuits can no longer be predicted as before; on the other hand, it has been found that the increase in the integration of chips will lead to The chip heats up, which brings about an increase in energy consumption, which limits the speed of the computer
However, energy consumption comes from irreversible operations in the calculation process

Embodiment Construction

[0077] The present invention is specifically described below in conjunction with embodiment

[0078] 1. Design of quantum processing unit framework

[0079] In realizing quantum algorithms, gate- and node-based quantum processing unit (QPU) design is the key to quantum computers. like figure 1 Shown is the design framework of this QPU, which can be implemented and simulated for existing quantum algorithms on a classical computer.

[0080] In this quantum circuit, there are two inputs |x> and |y>. The input data requires two registers, the first register is used to store the control register for |x>, and the second register is used to store the destination register for |y>. The first register is set at gate G c input, the second register is set at the gate G t input terminal. An n-qubit quantum register can be in all states from |0> to |2 at the same time n -1>this 2 n superposition of states. This effect allows quantum computers to compute functions of all possible in...

Abstract

The invention relates to a quantum computer quantum processing unit, a quantum circuit and a quantum circuit quantum algorithm, and belongs to the technical field of computers. The quantum processingunit (QPU) is composed of five modules and is controlled by a classic device. The quantum circuit defines two n quantum bit inputs |x) and |y) based on an SHOR algorithm. A control register and a target register are arranged. Gates Gc, G'c and Gt are defined for each algorithm. The quantum circuit quantum algorithm is a design scheme of a quantum processing architecture based on a Shor algorithm.The influence of feedback control on the proposed architecture is considered. The period searching during large number decomposition can be effectively ensured by utilizing feedback adjustment, so that the optimal performance of the quantum algorithm is effectively realized.

Description

technical field [0001] The invention relates to a quantum computer quantum processing unit, a quantum circuit and a quantum circuit quantum algorithm, belonging to the technical field of computers. Background technique [0002] Since the birth of the first electronic computer in 1946, computers have experienced four eras of tubes, transistors, small and medium-scale integrated circuits, and ultra-large-scale integrated circuits, and have been in rapid development, especially in the second half of the 20th century. , mankind has entered the information age. However, the development of semiconductor technology is constrained by Moore's Law, which indicates that the number of components that can be accommodated on an integrated circuit will double approximately every 18 to 24 months, and the performance will also double. That is to say, with the improvement of integration, when semiconductor devices are only as small as one atom, traditional computers will face an insurmountab...
