Intel Labs and parts research groups are silicon spin cubit, based on Intel’s transistor research and development in Hillsboro, Hillsboro. It proved to provide uniformity. This announcement is a remarkable achievement in the silicon spin cubit production sector, showing important progress in Intel’s transistor manufacturing process-based quantum chip manufacturing.
The study was made using the second generation silicone spin test chip. The researchers tested the device using Intel Cryoprober, a quantum dot test device operating at ultra-low temperature (1.7 Kelvin or minus 271.45 degrees), and succeeded in separating 12 quantum dots and four sensors. This represents the industry’s largest silicone electronic spin device with one electron for each location of the entire 300 mm silicone wafer.
The general silicone spin cubit is presented in one device, while Intel’s research proves that the research conducted by Intel is successful in the entire wafer. The test chip was produced using Intel’s state-of-the-art extreme infrared (EU) lithography and showed high uniformity, with a yield of 95%throughout the wafer. Cry offs, which can be powered by powerful software automation, are available for more than 900 single quantum dots and more than 400 dual points formed in the last electron, which is characterized by one degree higher than the zero point within 24 hours.
In addition, by increasing the yield and uniformity of the device specialized at low temperature compared to the previous Intel test chip, Intel identifies the area of the manufacturing process to be optimized using statistical process control. This is an important stepmother to accelerate learning and expand to thousands or millions of cubits for commercial quantum computers.
Intel was able to automate data collection across the wafer in a single electronics system through cross wafer yield to demonstrate the largest single and double bilateral dots. The increased yield and uniformity of the devices specialized at low temperature compared to the previous Intel test chip show an important step for expanding to thousands or potential cubits for commercial quantum computers.
James Clarke, Director of Intel’s quantum hardware division, said, Intel is creating continuous progress in the direction of manufacturing its own transistor manufacturing technology. The achievement of high yields and uniformity is that the manufacturing of quantum chips in Intel’s existing transistor process node is the right strategy, and that the technology for commercialization is a strong success strategy.
The entire contents of the study were unveiled on October 5, 2022, at the 2022 Silicon Quantum Electronic Workshop held at OXFORD, Quebec, Canada.
