In 2013, Rigetti Computing began creating quantum computers. As the company announced Friday, it will offer a true natural product starting in 2023. Next year, the Berkeley,administration-based company plans to release a fourth-generation machine called Ankaa and an expanded demonstration version called Lyra. According to inventor and company executive Chad Rigetti, the company hopes these machines will unlock a “quantum advantage” when highly evolved machines become devices that actually transmit information not available to traditional computers.
Quantum computers use material science features of ultra-small components: molecules and photons, to perform illogical calculations for traditional computer processors driving smartphones, portable workstations and data centers. Proponents of quantum computers believe they will lead to more efficient car batteries, non-use of drugs, more efficient radiation transfer, more successful production of ideas, and other advances. Until now, quantum computers have been an exceptionally expensive undertaking. Nevertheless, Rigetti is among a large group of people who aspire to become the first owners of quantum advantages. These include giant tech companies such as IBM, Google, Baidu and Intel, as well as practices: Quantinuum, IonQ, PsiQuantum, Pasqal and Silicon Quantum Computing.

“It’s a new race in this area,” Rigetti said in an exclusive interview before the company’s first day of investor relations.
In conjunction with the event, the company is revealing all the new details of a nearly complete innovation cluster, including manufacturing, hardware, applications that will run on computers, and cloud services for customers. “We’re building a complete rocket,” Rigetti said. Rigetti’s last name, though, is unknown, but it carries weight in this world. In February, Rigetti raised $262 million, becoming one of the few quantum computing companies in existence. Although the company made it clear that its quantum computing business could be a long-term one, speculators began to doubt it. The company’s stock price has fallen by nearly three-quarters since the opening bell, and the biggest damage was done recently when Rigetti announced a $4 million delay on a government contract that was supposed to make up the bulk of the company’s nearly $12 million to $13 million in annual revenue.
Quantum computer with more qubits
But the company says it has the right long-term approach. It will begin in early 2023 with Ankaa, an 84-qubit processor, the key processing element in a quantum computer. Four of these together form the basis of Lyra, a machine with 336 quantum bits. The names are astronomical: Ankaa is a star, and Lyra is a constellation.

“Rigetti isn’t promising the quantum advantage of a 336-cubic inch machine, but the company is hopeful. We think it’s absolutely feasible” Rigetti said.
More qubits are critical for the more complex algorithms needed to gain the quantum advantage. Rigetti hopes that customers in the financial, automotive and administration sectors will be willing to pay for this quantum computing power. Automotive companies can explore new battery technologies and optimize complex manufacturing operations, while financial companies are always looking for better ways to identify trends and make business decisions, Rigetti said.
Rigetti plans to combine its Ankaa modules into larger machines: a 1,000-kbps computer in 2025 and a 4,000-kbps model in 2027.
Rigetti is not the only company trying to build a rocket. IBM has a 127-kbit/s quantum computer today, and it is planning a 433-kbit/s model for 2023 and a 4,000-plus-kbit/s model for 2025. While the number of qubits is only one measure of the utility of a quantum computer, it is an important factor.
“What Rigetti is doing in terms of qubits pales in comparison to IBM,” said Paul Smith-Goodson, an analyst at Moor Insights & Strategy.
Rigetti’s Quantum Informatics offerings
Along with these machines, Rigetti plans to develop manufacturing, including expanding the company’s 5,000-square-foot plant in Fremont, California, where the chips are made, improving the error-correction technology needed to perform more complex quantum computing, and improving software and services so customers can perform these calculations. Indeed, it can be used
Cubits break down easily, so error-correcting is critical to the development of quantum informatics. As a better, less error-prone framework. Quantum computer manufacturers track this with a measurement called Gate Fidelity. Today, accuracy ranges from 95 to 97 percent, but fourth-generation Ankaa-based prototype systems have reached 99 percent, Rigetti said.
