1. A system for the quantum coherence preservation of a qubit, comprising:
an oscillator adapted to operate in a quantum mode and in a classical mode, the oscillator including a plurality of cascaded stages, each stage including:
a circuit adapted to perform a corresponding operation in either the classical mode or in the quantum mode,
an input, and
an output, wherein the stage is adapted to evolve a qubit between a first state on the input and a second state on the output,
wherein the stages are cascaded such that the input of one stage is coupled to the output of a previous stage and the input of a first stage of the cascaded stages is coupled to the output of a last stage of the cascaded stages to form a feedback circuit path, and
wherein the classical mode is adapted for performing a quantum operation simultaneously on a plurality of independent qubits.
