*This abstract for appeared for patent application  number 18018537 Titled 'QUANTUM COMPUTING DEVICE FOR DETERMINING A NETWORK PARAMETER'

==Simplified Explanation==

This abstract describes a quantum computing device and a method for determining a network parameter of a network of nodes. The method involves manipulating quantum states of qubits (quantum bits) in the device. The qubits are organized into two registers, each in an equal superposition state. The qubits in the first register influence the qubits in the second register using operators that represent the network. The method includes performing a first measurement on the qubits in the first register to estimate a principal eigenvalue. Then, a second measurement is performed on the qubits in the second register, and the results of this measurement, corresponding to the principal eigenvalue, are used to calculate the network parameter.


==Original Abstract Submitted==

Embodiments described herein relate to a quantum computing device, methods and apparatus for determining a network parameter of a network of nodes The method comprises manipulating quantum states of qubits of the quantum computing device, the qubits arranged into a first and a second register each in equal superposition, the qubits of the first register conditionally influencing the qubits of the second register using operators representing the network. The method performs a first measurement on the qubits of the first register to estimate a principal eigenvalue, then performs a subsequent second measurement on the qubits in the second register, and uses the results of the second measurement corresponding to the principal eigenvalue to calculate the network parameter.
