Quantum practicality is what Intel calls the transition of quantum technology from the lab to the marketplace, potentially transforming what companies do in critical areas such as drug development, predicting natural disasters, and inventing new materials. The ability to scale, and control, thousands of qubits [the fundamental units of quantum information] at the same time without a corresponding decline in qubit fidelity and performance will be crucial to the successful application of quantum computing to practical problems, according to Intel.

“Back in 2018, we were saying we thought [quantum practicality] was going to happen in 10 to 12 years,” says Jim Clarke, director of the Quantum Hardware Research group at Intel. Clarke has co-authored more than 50 papers, holds several patents and has received a Ph.D. in physical chemistry from Harvard University.

Regardless of recent breakthroughs by Intel and others, the expectation of getting to quantum practicality by the end of this decade hasn’t changed. “Controlling qubits is actually very difficult,” says Clarke, “and one approach is to use racks and racks of electronics.” Instead, Intel has developed a customized control chip that sits inside the refrigerators where quantum computing occurs.

“Horse Ridge” is what Intel calls its cryogenic control chip (named after one of the coldest places in Oregon) and its placement inside the refrigerator reduces significantly the amount of wiring required. This, in turn, will help Intel’s quantum solution to eventually reach a scale of thousands of qubits, which the company argues is what will be required for quantum practicality. ... "
