In the production of quantum chips for a technology wave of powerful computers, Intel has achieved a key milestone.
Extreme ultraviolet lithography, or EUV manufacturing, of silicon spin qubit devices has been claimed to have achieved the highest results ever recorded at Intel’s Gordon Moore Park transistor research and development facility in Hillsboro, Oregon. The company’s engineers and researchers have created quantum chips with outstanding “uniformity,” resulting in production rates of 95% across the 300mm silicon wafer.
James Clarke, the director of Quantum Hardware, talked about his company’s progress in creating silicon spin qubits using current transistor manufacturing technologies. It is crucial for Intel to take use of its capabilities in semiconductor manufacturing if it wants to succeed in the market. The company’s silicon chip refining samples are expected to be used with Intel’s cutting-edge quantum computing.
Intel’s most recent blog post on their progress in building quantum chips was inspired by the creation and testing of a second-generation silicon spin test chip. The Intel Cryoprober, which runs at incredibly low temperatures (1.7 Kelvin or -271.45 degrees Celsius) to retain the stability of the quantum states and make them usable for computing tasks, was used to test the final produced quantum devices. Room-temperature quantum computers are still being developed, which is another challenge for the nascent sector.
On the 300mm wafer, the cryoprober verified that 95% of the qubit packing chips were operating as anticipated. This is especially excellent news for Intel because, up until now, most efforts to produce quantum chips included fabricating each chip individually. With the previously stated excellent uniformity and yields, Intel’s EUV method looks to be able to produce several quantum devices on a wafer at this time.
Intel will use statistical process control to make improvements now that its second-gen silicon spin test chip has undergone extensive testing, extending the advancements previously made to target the next-gen. The goal is for computer technology companies like Intel to someday be able to produce quantum devices with millions of qubits, and in 2022, we are witnessing the crucial early phases of this growing process. We’re eager to see where things go in the years to come since quantum computing now has the ability to perform some stunning computations.
