Abstract: A method useful for network and spectrum defense which operates to analyze cyber data and spectra while performing real time optimization which is based on the analyzed cyber data or spectrum. The method utilizes quantum computing and reconfigurable qubits with built-in memory to sample a target cyber data or spectrum, search through the sample and determine a desired or required network or spectrum reallocation, and determine optimal values for its order parameters and Hamiltonian and tune the qubits in accordance with the determination. An embodiment may provide for spectrum optimization that minimizes frequency bandwidth, power, and bit error rate. The desired or required network or spectrum reallocation and optimal values order parameters and Hamiltonian may be stored in the built-in memory to facilitate machine learning.
