System and method for latency-aware mapping of quantum circuits to quantum chips

A quantum computer, comprising:

• a refrigeration container defining a refrigeration chamber therein;
• a quantum processor disposed inside the refrigeration chamber, the quantum processor comprising a plurality of qubits, at least two qubits in the plurality of qubits being selectable to generate a quantum circuit, the quantum circuit having a latency;
• wherein the quantum processor is configurable to construct the quantum circuit using a quantum circuit generator in communication with the plurality of qubits, the quantum circuit generator comprising:
• a controller;
• a plurality of analog conversion units (ACUs) operatively connected to the controller, each ACU being operatively connected to a corresponding qubit of the plurality of qubits, wherein each ACU is configured to convert a digital input from the controller into an analog input at a microwave frequency to control a quantum state of the corresponding qubit of the plurality of qubits;
• wherein the controller generates the quantum circuit by selecting the at least two qubits of the plurality of qubits to be controlled by inputs from the controller that are mapped to corresponding classical bits so that the latency of the quantum circuit is less than or equal to a threshold latency that is less than or equal to a coherence time of the quantum circuit.

A computer readable medium on which is stored non-transitory computer-executable code, which when executed by a controller causes the controller to:

• map at least two qubits in a plurality of qubits to classical bits;
• and
• generate a quantum circuit by selecting the at least two qubits of the plurality of qubits to be controlled by inputs from the controller mapped to corresponding classical bits;
• determine a latency of the generated quantum circuit;
• and
• select the at least two qubits in the plurality of qubits so that the latency of the quantum circuit is less than or equal to a threshold latency that is less than or equal to a coherence time of the quantum circuit generated.
