Embodiment Construction

[0056] The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0057] It should be noted that the terms "first" and "second" in the description and claims of the present invention are used to distinguish similar objects, but not necessarily used to describe a specific order or sequence.

[0058] Association rule mining allows us to discover the relationship between items (item and item) from the data set. It has many application scenarios in our life. "Shopping basket analysis" is a common scenario. This scenario can be obtained from consumption Discover the relationship between commodities in the transaction records of buyers, and then bring more sales through bundled sales of commodities or related recommendations. Therefore, association rule mining is a very useful technique.

[0059] Based on this, the present invention firstly introduces a method f...

Abstract

The invention discloses a method and a device for querying transaction elements by using a quantum circuit. The method comprises the following steps: obtaining a transaction database at least containing transaction indexes and corresponding transaction elements, utilizing a quantum logic gate and quantum bits; constructing a first quantum circuit coded with the transaction index, the transaction element and the binary value of the transaction element to be inquired, and running the first quantum circuit, outputting a quantum state containing the binary value of each transaction index and a first amplitude corresponding to the quantum state, and determining a transaction index result corresponding to the to-be-queried transaction element according to the probability corresponding to each first amplitude. By utilizing the embodiment of the invention, a quantum circuit can be designed in the field of quantum computing, so that the defect of relatively low transaction element query efficiency in the prior art is overcome.

Description

technical field [0001] The invention belongs to the technical field of quantum computing, in particular to a method and device for querying transaction elements by using quantum circuits. Background technique [0002] 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 computer has become a key technology under research because of its ability to deal with mathematical problems more efficiently than ordinary computers, for example, it can speed up the time to crack RSA keys from hundreds of years to hours. [0003] Quantum computing simulation is an analog computing that follows the laws of quantum mechanics by means of numerical computing and computer science. As a simulation program, it uses the high-speed computing capabi...
