CALIBRATION OF QUANTUM PROCESSOR OPERATOR PARAMETERS: abstract simplified (18311178)

• This abstract for appeared for patent application number 18311178 Titled 'CALIBRATION OF QUANTUM PROCESSOR OPERATOR PARAMETERS'

Simplified Explanation

The abstract describes methods, systems, and apparatus for determining operating parameters for a quantum processor with multiple interacting qubits. It involves generating a graph representation of the qubits and their interactions, selecting an algorithm to traverse the graph, identifying subsets of nodes or edges that are related based on the traversal rule, and determining calibrated values for these subsets using a stepwise constrained optimization process. The constraints for the optimization process are determined using previously calibrated operating parameters.

Original Abstract Submitted

Methods, systems and apparatus for determining operating parameters for a quantum processor including multiple interacting qubits. In one aspect, a method includes generating a graph of nodes and edges, wherein each node represents a respective qubit and is associated with an operating parameter of the respective qubit, and wherein each edge represents a respective interaction between two qubits and is associated with an operating parameter of the respective interaction; selecting an algorithm that traverses the graph based on a traversal rule; identifying one or multiple disjoint subsets of nodes or one or multiple disjoint subsets of edges, wherein nodes in a subset of nodes and edges in a subset of edges are related via the traversal rule; and determining calibrated values for the nodes or edges in each subset using a stepwise constrained optimization process where constraints are determined using previously calibrated operating parameters.
