Abstract
A reservoir computer. In some embodiments, the reservoir computer includes a series array of Josephson junctions, a coupling impedance, and a readout circuit. In some embodiments, the series array of Josephson junctions includes a plurality of Josephson junctions, connected in series; the coupling impedance is connected in parallel with the series array of Josephson junctions; and the readout circuit is connected to at least three nodes of the series array of Josephson junctions.
Claims12
A system, comprising:
- a series array of Josephson junctions;
- a coupling impedance;
- and
- a readout circuit,
- wherein:
- the series array of Josephson junctions comprises a plurality of Josephson junctions, connected in series,
