Description

technical field [0001] The invention belongs to the technical field of quantum computing, in particular to a method and device for constructing a quantum circuit of a QRAM architecture. Background technique [0002] A quantum computer is a kind of physical device that follows the laws of quantum mechanics to perform high-speed mathematical and logical operations, store and process quantum information. When a device processes and computes quantum information and runs quantum algorithms, it is a quantum computer. Quantum computers have become a key technology under research because of their ability to handle mathematical problems more efficiently than ordinary computers. For example, it can speed up the time to crack an RSA key from hundreds of years to hours. [0003] The development of efficient processes for retrieving classical / quantum data from databases and transforming them into quantum superposition states is one of the most fundamental issues in the practical impleme...
