Atom Computing announced that it has created a 1,225-bit atomic array in its next-generation quantum computing platform that currently houses 1,180 qubits. This is the first time a company has crossed the 1,000-qubit threshold for a universal gate-based system, which is scheduled to be released next year. This marks an industry milestone for fault-tolerant quantum computers in solving large-scale problems.

CEO Rob Hays said rapid scalability is a key advantage of AtomComputing's unique atomic array technology. "This order of magnitude leap—from 100 qubits to more than 1,000 qubits in a generation—suggests that our atomic array systems are rapidly surpassing more mature qubit modes. Scaling to large numbers of qubits is critical for fault-tolerant quantum computing, which is why we have focused on it from the beginning. We are working closely with our partners to explore near-term applications that can take advantage of these larger-scale systems."

Paul Smith-Goodson, vice president and principal analyst at MoorInsights&Strategy, said the 1,000-plus-bit milestone makes Atom Computing a strong contender in the race for fault-tolerant systems.

"It's impressive that Atom Computing, which is only five years old, can compete with larger companies with more resources and maintain its advantage. The company has been focused on expanding its atomic array technology and is making rapid progress," he said.

Fault-tolerant quantum computers that can overcome errors in calculations and provide accurate results will require hundreds of thousands or even millions of physical qubits as well as other key capabilities, including:

Long coherence time. The company has achieved a record coherence time, demonstrating that its qubits can store quantum information for 40 seconds.

Medium circuit measurements. Atom demonstrated the ability to measure the quantum state of a specific qubit during a calculation and detect certain types of errors without disturbing other qubits.

High fidelity. It can continuously and accurately control qubits and reduce errors in the calculation process.

Correction. The ability to correct errors in real time.

Logical qubits. Implement algorithms and controls to combine large numbers of physical qubits into "logical qubits" that produce correct results even when errors occur.

Hayes said Atom Computing will continue to implement these capabilities with its next-generation systems, which will provide new opportunities for its partners.

Guenter Klas, head of Vodafone's Quantum Research Cluster, said: "We welcome innovations like AtomComputing that use neutral atomic methods to build quantum computers. Ultimately, we hope that quantum algorithms can bring about economic changes and bring new opportunities. For this, scalable hardware, high fidelity and long coherence times are very promising elements."

Tommaso Demarie, CEO of EntropicaLabs, a strategic partner of AtomComputing, said: "The development of quantum technology with more than 1,000 qubits marks a remarkable achievement for the AtomComputing team and the industry as a whole. With increased computing power, we can now delve into the complex field of error correction schemes and design and implement various strategies to pave the way for more reliable and scalable quantum computing systems. Entropica is keen to work with AtomComputing because we create software that can take full advantage of its large-scale quantum computers."

Atom Computing is currently working with enterprise, academic and government users to develop applications and set aside time for the system, which will be operational in 2024.
