Control system architecture for qubits

A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform method steps for controlling a qubit array, the method steps comprising:

• generating a first signal to set a bias point of a plurality of qubits to a first position, in which each qubit is unenabled and not responsive to a control signal;
• generating a second signal to move the bias point of selected qubits from the first position to a second position, in which each selected qubit is enabled and responsive to the control signal;
• and
• generating a control signal to control operation of the selected qubits.

A method of controlling a qubit array comprising:

• dividing a number of physical qubits into logical blocks, wherein each logical block includes a plurality of physical qubits;
• applying a first signal to one or more logical blocks to set a bias point of each physical qubit to a first position, in which the physical qubit is unenabled and not responsive to a control signal;
• applying a second signal to one or more logical blocks to move the bias point of each physical qubit that is in the first position to a second position, in which the physical qubit is unenabled and not responsive to the control signal;
• applying a third signal to one or more logical blocks to move the bias point of each physical qubit that is in the second position to the third position, in which the physical qubit is enabled and responsive to the control signal;
• and
• applying the control signal to one or more logical blocks, in which the bias point of each physical qubit is in the first, second or third position, to control an operation of one or more logical blocks in which the bias point of each physical qubit is in the third position.
