Intel has unveiled a new quantum computer chip, Tunnel Falls, with 12 quantum bits made of silicon.
A schematic representation shows an electron under 12-qubit quantum dot gates. Fabricated on 300-millimeter wafers, Tunnel Falls leverages Intel’s most advanced transistor fabrication capabilities, such as extreme ultraviolet lithography and advanced materials processing techniques. This makes the chip a single electron transistor and allows Intel to fabricate Tunnel Falls with few changes to a standard complementary metal oxide semiconductor logic processing line.

It is fabricated on 300-millimeter wafers and leverages Intel’s most advanced transistor fabrication capabilities. Intel makes new quantum chip available to university and federal research labs to grow the quantum computing research community.
To further address this, Intel is collaborating with LQC as part of the Qubits for Computing Foundry program through the U.S. Army Research Office to provide Intel’s new quantum chip to research laboratories. The collaboration with LQC will help democratize silicon spin qubits by enabling researchers to gain hands-on experience working with scaled arrays of these qubits.
Dr. Dwight Luhman, distinguished member of Technical Staff at Sandia National Laboratories, said, “Sandia National Laboratories is excited to be a recipient of the Tunnel Falls chip. The device is a flexible platform enabling quantum researchers at Sandia to directly compare different qubit encodings and develop new qubit operation modes, which was not possible for us previously.
