Application: Quantum architecture biasing scheme (Patent ID: US20240210496A1)
The patent filed by IBM describes a radio-frequency (RF) to direct current (DC) converter that utilizes a Josephson junction (JJ) to generate a steady state voltage linearly dependent on the RF frequency. The converter includes a DC to single flux quantum (SFQ) converter and a rapid SFQ pulse doubler to affect the JJ, with the SFQ pulses being generated by converting RF current. The system also includes a resistor connected to the JJ for directing RF current to an external quantum mechanical device.
Furthermore, the patent outlines a quantum mechanical system incorporating the RF to DC converter, where the RF current passing through the resistor is directed to a quantum mechanical device such as a qubit or superconducting quantum interference device. The system includes multiple stages of the SFQ pulse doubler to generate RF electrical current and allows for multiple RF to DC converters to be addressable for routing SFQ pulses to specific devices. Additionally, the system features bipolar quantized supercurrent generators (QSGs) inductively coupled to quantum mechanical devices, with each QSG comprising a superconducting quantum interference device (SQUID) loop with Josephson junctions and an inductor.
