Abstract
Systems, methods and apparatus for a scalable quantum processor architecture. A quantum processor is locally programmable by providing a memory register with a signal embodying device control parameter(s), converting the signal to an analog signal; and administering the analog signal to one or more programmable devices.
Claims34
A quantum processor comprising:
- a plurality of programmable devices including a plurality of qubits;
- and
- a memory administration system including a plurality of communication conduits, wherein the memory administration system is configured to couple to at least one of the programmable devices via at least one of the communication conduits, and wherein the memory administration system includes at least one digital-to-analog converter (DAC).
A method of programming a quantum processor, wherein the quantum processor includes a plurality of programmable devices and a memory administration system having at least one digital-to-analog converter (DAC), the method comprising:
- using the memory administration system to program a first DAC with a first digital signal that embodies a control parameter for a first programmable device;
- using the first DAC to convert the first digital signal to a first analog signal;
- and
- administering the first analog signal to the first programmable device.
