Control system architecture for qubits

Abstract

A control system architecture for quantum computing includes an array of qubits, which is divided into a plurality of sub-arrays based on a first direction and a second direction, the second direction intersecting the first direction, a plurality of control lines each coupled to a corresponding sub-array of qubits in the first direction, a plurality of enable/unenable lines each coupled to a corresponding sub-array of qubits in the second direction, a controls signal source that generates a control signal, wherein the control lines are used to apply the control signal commonly to one or more sub-arrays of qubits in the first direction, an enable/unenable signal source that generates a enable signal, wherein the enable/unenable lines are used to apply the enable signal independently to the corresponding sub-array of qubits in the second direction to set a bias point of each qubit of the corresponding sub-array of qubits in the second direction between a first position, in which the qubit is unenabled and not responsive to the control signal, and a second position, in which the qubit is enabled and responsive to the control signal.
