Novel chip fabrication process for scalable, high performing QPUs
We believe quantum computers capable of addressing real-world problems will require hundreds to thousands of high performing qubits. Because qubits are sensitive to noise and other external factors, an important factor for scaling to higher qubit count systems is improving control over the materials, design, and environment of qubits. In August 2024, Rigetti introduced a novel chip fabrication technique, ABAA, that allows for qubit frequencies to be precisely targeted prior to a chip being packaged. The technique entails applying a series of low, alternating voltages at room temperature to the junctions that form the qubit. Unlike more complicated solutions that address the problem of tuning frequency, which often require laser trimming of the chip, ABAA is a simple and scalable process.
The Company found that leveraging ABAA enables improved execution of 2-qubit gates and a reduction in defects, which both contribute to higher fidelity.
The Company is leveraging the ABAA technique to fabricate chips for the Novera QPU and the upcoming Ankaa-3 system.
