Intel reaches new milestone in quantum chip manufacturing

Intel, competitor amd and leading manufacturer processorsshowed the industry’s highest performance and stability to date for silicon spin qubit devices Developed at the Intel Transistor Research and Development Center.

If you don’t understand this phrase very well, stick with this: is an important milestone for scaling and quantum chip production work in Intel’s transistor manufacturing processes..

The study was conducted using a second-generation Intel silicon test chip. Device testing with Intel CryoTestera device for testing quantum dots operating at cryogenic temperatures (-271.45 degrees Celsius), the team isolated 12 quantum dots and four sensors.

This result represents the largest electronic spin silicon device in the industry., with one electron at each location on a 300mm silicon wafer. Without a doubt, this is a very different job than working with traditional processors. AMD is also involved in this fight.

Quantum processor very close

Current silicon spin qubits are typically found in a single device, while Intel research shows success in a whole wafer.

Manufactured using extreme ultraviolet lithography (EUV), chips show remarkable uniformity with 95% yield across the entire wafer.

Application of cryoprocessoralong with reliable automation software, allowed to obtain more than 900 individual quantum dots and more than 400 double dots in the last electronwhich can be characterized one degree above absolute zero in less than 24 hours.

Improved performance and device stability at low temperatures compared to previous Intel test chips. allows that company to use statistical process control to identify areas of the manufacturing process that need to be optimized.

It speeds up learning and represents an important step towards scaling up to the thousands or potentially millions of qubits needed for a commercial quantum computer.. Definitely Intel took a giant step in his quantum career.
