Circuitry and processes are disclosed that use conventional electronic circuits (comprising, for example, phase locked loops, pulse width modulators, phase modulators, digital logic gates, etc.) to enable quantum algorithms. Such circuitry and processes achieve the requirement for non-quantum devices to enable quantum algorithms: the tensor product entanglement of signals representing quantum states. Such circuitry and processes are readily usable by current Electronic Design Automation tools, to design, verify and emulate applications such as fast, very large number factoring for use in decryption. Also, the independent Claims concisely signify embodiments of the claimed inventions.
