  • Publication number: 20210232961
    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.

  • Patent number: 8629480
    Abstract: A hetero-junction tunneling transistor having a first layer of p++ silicon germanium which forms a source for the transistor at one end. A second layer of n+ silicon material is deposited so that a portion of the second layer overlies the first layer and forms the drain for the transistor. An insulating layer and metallic gate for the transistor is deposited on top of the second layer so that the gate is aligned with the overlying portions of the first and second layers. The gate voltage controls the conduction between the source and the drain and the conduction between the first and second layers occurs by vertical tunneling between the layers.
