Intel Hits Key Milestone in Quantum Chip Production Research

Business Wire
Intel demonstrates exceptional yield of
quantum dots arrays, showing promise for large-scale qubit
production using transistor fabrication technology.
The Intel Labs and Components Research organizations have
demonstrated the industry’s highest reported yield and uniformity
to date of silicon spin qubit devices developed at Intel’s
transistor research and development facility, Gordon Moore Park at
Ronler Acres in Hillsboro, Oregon. This achievement represents a
major milestone for scaling and working towards fabricating quantum
chips on Intel’s transistor manufacturing processes.

The research was conducted using Intel’s second-generation
silicon spin test chip. Through testing the devices using the Intel
cryoprober, a quantum dot testing device that operates at cryogenic
temperatures (1.7 Kelvin or -271.45 degrees Celsius), the team
isolated 12 quantum dots and four sensors. This result represents
the industry’s largest silicon electron spin device with a single
electron in each location across an entire 300 millimeter silicon
wafer.
Today’s silicon spin qubits are typically presented on one
device, whereas Intel’s research demonstrates success across an
entire wafer. Fabricated using extreme ultraviolet (EUV)
lithography, the chips show remarkable uniformity, with a 95% yield
rate across the wafer. The use of the cryoprober together with
robust software automation enabled more than 900 single quantum
dots and more than 400 double dots at the last electron, which can
be characterized at one degree above absolute zero in less than 24
hours.
Increased yield and uniformity in devices characterized at low
temperatures over previous Intel test chips allow Intel to use
statistical process control to identify areas of the fabrication
process to optimize. This accelerates learning and represents a
crucial step toward scaling to the thousands or potentially
millions of qubits required for a commercial quantum computer.
Additionally, the cross-wafer yield enabled Intel to automate
the collection of data across the wafer at the single electron
regime, which enabled the largest demonstration of single and
double quantum dots to date. This increased yield and uniformity in
devices characterized at low temperatures over previous Intel test
chips represents a crucial step toward scaling to the thousands or
potentially millions of qubits required for a commercial quantum
computer.
“Intel continues to make progress toward manufacturing silicon
spin qubits using its own transistor manufacturing technology,”
said James Clarke, director of Quantum Hardware at Intel. “The high
yield and uniformity achieved show that fabricating quantum chips
on Intel’s established transistor process nodes is the sound
strategy and is a strong indicator for success as the technologies
matures for commercialization.
“In the future, we will continue to improve the quality of these
devices and develop larger scale systems, with these steps serving
as building blocks to help us advance quickly,” Clarke said.
Full results of this research will be presented at the 2022
Silicon Quantum Electronics Workshop in Orford, Québec, Canada on
Oct. 5, 2022.
