Apparatus and method for quantum processing

This invention describes a quantum computer built from a grid of tiny quantum bits, or qubits. These qubits are specifically made from phosphorus atoms embedded in a semiconductor material, using either their nuclear or electron spin. The computer is controlled by electrical wires placed above and below the qubit grid, allowing it to perform a specific type of calculation called adiabatic quantum computation with built-in error correction.

Why it matters: Filed before significant progress in quantum error correction and silicon-based qubit fabrication. The tools and techniques for realizing such complex quantum processors are now more advanced.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedAtomic-scale semiconductor fabrication, cryogenic environment
