Abstract
Techniques regarding a threshold scheme for quantum recommendation algorithms are provided. For example, one or more embodiments described herein can comprise a system, which can comprise a memory that can store computer executable components. The system can also comprise a processor, operably coupled to the memory, and that can execute the computer executable components stored in the memory. The computer executable components can comprise a quantum recommendation component that can project a preference vector onto a portion of a Hilbert space based on a value of a qubit phase register. The portion of the Hilbert space can encode singular values of a preference matrix that are greater than or equal to a defined threshold.

A system, comprising:
- a memory that stores computer executable components;
- and
- a processor, operably coupled to the memory, and that executes the computer executable components stored in the memory, wherein the computer executable components comprise:
- a quantum recommendation component that projects a preference vector onto a portion of a Hilbert space based on a value of a qubit phase register, wherein the portion of the Hilbert space encodes singular values of a preference matrix that are greater than or equal to a defined threshold.
A computer program product for implementing a thresholding scheme for a qubit phase register, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:
- project, by a system operatively coupled to the processor, a preference vector onto a portion of a Hilbert space based on a value of the qubit phase register, wherein the portion of the Hilbert space encodes singular values of a preference matrix that are greater than or equal to a defined threshold.
A system, comprising:
- a memory that stores computer executable components;
- and
- a processor, operably coupled to the memory, and that executes the computer executable components stored in the memory, wherein the computer executable components comprise:
- a quantum recommendation component that implements a quantum recommendation algorithm using a thresholding scheme that projects a preference vector onto a portion of a Hilbert space based on quantum states of a qubit phase register and a defined threshold.
