Advanced processing apparatus comprising a plurality of quantum processing …

This invention describes a quantum computer built entirely on silicon chips, similar to regular computer processors. It uses a grid of tiny structures, each designed to trap a single electron whose spin acts as a quantum bit (qubit). These qubits are controlled by electrical signals generated by transistor-based circuits, allowing for quantum calculations.

Why it matters: Filed in 2016, this patent's focus on scalable, all-silicon quantum computing was aspirational. By 2026, significant advancements in semiconductor manufacturing and quantum control have made fabricating and operating 2D arrays of silicon spin qubits much more feasible, aligning with the patent's proposed architecture.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedCustom silicon, quantum dot fabrication
