Description

Abraham and a large engineering team reported in 2026 a silicon quantum processing unit with digital control. Quantum computers need many qubits, the basic units of quantum information, that can be built at factory scale. Their unit joins a custom cryogenic chip that generates control signals, a dense superconducting ribbon cable, and a low-noise silicon qubit chip. The qubit chip holds a three-rail array of 54 quantum dots that can host up to eighteen exchange-only qubits.

Single-qubit and entangling operations on the system beat prior exchange-only results by about tenfold on key quality measures. The team also ran a distance-five repetition code and a distance-two error-detecting code, two schemes that catch quantum errors. The authors argue this split solves a wiring bottleneck for larger machines.
