The BT is a fully quantum non-dissipative device facilitating precise delivery of the quantised current to the circuit, I=2efn (where n is an integer, e is the charge of an electron, and f is the microwave frequency). It does not have an analogue in classical electronics, but it is required for quantum ones. The amplitude of the quantized current is adjustable through four controls: the gate or bias voltage and the frequency or amplitude of the microwave. The device features Josephson junctions operating in the regime of Bloch oscillations, an isolating electromagnetic circuit and microwave feeding leads. BT operates at a bias of ∼ 5 μV, and can deliver the quantized currents of up to 10 nA.
