Intel announced the release of its latest quantum chip, a 12-qubit silicon-based chip dubbed “Tunnel Falls” by the firm. Tunnel Falls is intended to be a research test chip: it is still a stepping stone towards the genuine Quantum Processing Units of the future.
Before any work can be done on future quantum computers, the algorithms, learning, and how-to must be started now. One obstacle is the complexity in generating quantum computing hardware; this is why only a few large businesses are actively developing quantum computing hardware.
Intel’s strategy of leveraging silicon-spin qubits is a quantum computing technology that can be built on Intel’s years of chip manufacturing expertise, applying its knowledge of which levers to move in order to boost yield rates.
Intel claims that Tunnel Falls production achieved a 95% yield rate with voltage uniformity comparable to chips created using the more traditional CMOS method.
A single 300mm wafer, according to the business, produces 24,000 quantum dot test chips with a 95% yield. Intel’s qubit selection fits in perfectly with cutting-edge transistor production – one of Tunnel Fall’s qubits is around the size of a transistor.
Intel’s Tunnel Falls is intended to drive existing research activities, with the corporation collaborating with the University of Maryland, College Park’s Qubit Collaboratory (LQC), a national-level Quantum Information Sciences (QIS) Research Centre.
As part of this agreement, Intel will participate in the Qubits for Computing Foundry (QCF) programme, which is affiliated with the United States Army Research Office, to supply Intel’s new quantum chip to research facilities.
