An artificial synapse circuit

An artificial synapse circuit comprising:

• a SQUID ring comprising a first junction, a second junction, a first inductor and a second inductor;
• a trigger circuit comprising an input, a third inductor paired with the first inductor, a fourth inductor paired with the second inductor, a first resistor connected in series with the third inductor and the fourth inductor, and a switch, and when a signal comes from the input while the switch is in conduction state, ensuring that a portion of the current passing through the third inductor is transmitted to the first inductor and a portion of the current passing through the fourth inductor is transmitted to the second inductor;
• a plurality of weighting circuits in which a plurality of single blocks are formed by connecting together in series, each comprising a SQUID ring and a trigger circuit;
• and
• a converter circuit adapted to convert the total weights calculated by the weighting circuits into quantized pulses.
