Abstract
The present disclosure provides a scalable architecture for an advanced processing apparatus for performing quantum processing. The architecture is based on an all-silicon CMOS fabrication technology. Transistor-based control circuits, together with floating gates, are used to operate a two-dimensional array of qubits. The qubits are defined by the spin states of a single electron confined in a quantum dot.
Claims14
An advanced processing apparatus, comprising:
- a plurality of quantum processing elements arranged in a 2D matrix;
- each processing element comprising silicon and a dielectric material forming an interface and an electrode arrangement suitable to confine one or more electrons or holes in the silicon, for each quantum processing element, to form a quantum dot operable as a qubit;
- a plurality of interconnected control members forming a matrix of control members;
- each control member comprising a silicon metal-oxide-semiconductor transistor disposed above a respective quantum processing element and configured to interact with the electrode arrangement to perform quantum operations with the processing element;
- and
- a plurality of control lines;
- each control line being connected to a plurality of control members via the metal-oxide-semiconductor transistors to enable simultaneous operation of a plurality of processing elements.
