Chapter 1: The Dawn of Multi-Chip Quantum Processors

In a significant advancement within quantum technology, Rigetti Computing has unveiled the first multi-chip quantum processor. This marks a pivotal milestone towards the development of scalable and commercially viable quantum computing systems.

Experts estimate that achieving at least 1,000 qubits is essential for deriving initial value from quantum computers, while a million qubits are often referenced as the benchmark for practical applications. Currently, we are in the nascent phase of reaching this ambitious objective, as the most advanced quantum processors today operate with fewer than 100 qubits.

Researchers are diligently striving to integrate as many high-quality qubits as possible onto a single quantum processor, making this recent breakthrough particularly noteworthy. Just months ago, developers from the Netherlands established the first rudimentary Quantum Network connecting three quantum processors. Now, Rigetti has added to the quantum achievements with what it touts as the world’s first multi-chip quantum processor.

According to their announcement, this processor features a proprietary modular architecture aimed at expediting the commercialization of quantum technology and addressing critical scalability issues essential for developing fault-tolerant quantum systems. Rigetti plans to offer an 80-qubit system powered by this innovative multi-chip technology on its Quantum Cloud Services platform later this year.

“We’ve developed a fundamentally new approach to scaling quantum computers. Our proprietary innovations in chip design and manufacturing have unlocked what we believe is the fastest path to building the systems needed to run practical applications and error correction.” ~ Chad Rigetti, Founder & CEO of Rigetti Computing

Section 1.1: Technical Innovations

The new quantum systems will be available for Rigetti customers through the firm’s Quantum Cloud Services platform, aligning with offerings from industry leaders like IBM and Google. These quantum systems utilize superconducting qubits, arranged in arrays on a processor, controlled via microwave pulses. This setup allows for encoding, manipulating, and reading quantum information.

Scaling the number of qubits on a single processor presents a significant challenge. Qubits must be maintained in ultra-cold environments close to absolute zero to preserve their delicate quantum state. Rigetti has tackled this issue through a modular approach that significantly simplifies manufacturing processes, enabling predictable and accelerated scaling.

They have developed technology to connect multiple identical chips into a large-scale quantum processor. This method promises diverse scaling options for future systems, positioning Rigetti advantageously against technology giants like Google, IBM, Microsoft, and Amazon. Recently, IBM laid out its roadmap to develop a 1,121 qubit device by 2023.

Overall, the entry of smaller companies into the quantum computing arena highlights their potential to explore innovative solutions for increasing superconducting qubits, thereby speeding up the evolution of quantum computers.
