QUANTUM CIRCUITS FOR MATRIX TRACE ESTIMATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240020564 titled 'QUANTUM CIRCUITS FOR MATRIX TRACE ESTIMATION

Simplified Explanation

The abstract describes systems and methods for operating a quantum system. The quantum system includes quantum hardware with multiple qubits, and a controller can generate a command signal. An interface controls the quantum hardware based on the command signal to generate a random state vector represented by the qubits. The random state vector has a specific number of independent entries. The interface also controls the quantum hardware to determine moments of a matrix based on the random state vector. The controller can output the moments of the matrix to a computing device to estimate the trace of the matrix using the moments.
