Superconducting Quantum Bit Control Apparatus - A simplified explanation of the abstract
This abstract first appeared for US patent application 18344427 titled 'Superconducting Quantum Bit Control Apparatus
Simplified Explanation
The patent application describes a quantum bit control apparatus that manipulates a quantum bit in a quantum chip.
- The apparatus includes a first coupling means that receives multiple frequency-mixed control signals of different frequencies and sends them to a signal extraction means.
- A second coupling means receives local oscillation signals and sends them to the signal extraction means.
- The frequency-mixed control signals and local oscillation signals are generated in a higher temperature region compared to a lower temperature region.
- The signal extraction means filters the received control signals and local oscillation signals and performs down-conversion to restore a control signal for manipulating the quantum bit.
Original Abstract Submitted
A quantum bit control apparatus includes a first coupling means configured to receive a plurality of frequency-mixed control signals of different frequencies from a first transmission medium, and send the plurality of frequency-mixed control signals of different frequencies to the signal extraction means. A second coupling means is configured to receive local oscillation signals from a second transmission medium, and send the local oscillation signals to the signal extraction means. The frequency-mixed control signals and the local oscillation signals are generated in a first temperature region, and a temperature of the first temperature region is higher than that of the second temperature region. A signal extraction means filters the received frequency-mixed control signals and the received local oscillation signals, and performs down-conversion on the filtered control signals and the filtered local oscillation signals to restore a control signal that is used to manipulate a quantum bit in the quantum chip.
