Highlights

6,100-qubit neutral-atom system operates at room temperature
Coherence time reaches 12.6 seconds, fidelity 99.98%
Atom shuttling demonstrated for quantum error correction

Scientists have built a 6,000-qubit quantum system as a result of a remarkable experiment. This result helps to redefine the future of computing, although it functions at room temperature. The achievement denotes a significant step, as this facilitates the development of large-scale quantum computers that can address problems beyond classical machines. Quantum systems need to be kept extremely cold commonly; however, this one uses neutral atoms, and it is managed by lasers, still works with accuracy. Experts noted that this progress brings us closer to having practical quantum computers, allowing us to work in normal conditions."

Caltech Scientists Build 6,000-Qubit Quantum System That Works at Room Temperature, Redefining the Future of Computing

According to a Live Science report, researchers from the California Institute of Technology created the system using optical tweezers to trap over 6,100 atoms arranged in a grid. The atoms were managed by using finely tuned laser beams. It is also allowing scientists to have a notable coherence time of 12.6 seconds and an operation fidelity of 99.98%. These outcomes point to one of the most stable and large-scale quantum systems ever built. All are functioning at normal laboratory temperatures.

The team also demonstrated that atoms could be moved across tiny distances without losing their quantum states—a key requirement for building fault-tolerant and scalable machines. This ability to “shuttle” atoms opens the door to more complex operations, such as implementing quantum error correction and linking multiple processors together.

Quantum Computers Achieve Unconditional Advantage Over Classical Machines, Study Shows

To existing superconducting and ion-trap technologies, this development makes neutral-atom platforms strong competitors. This relies on expensive cooling systems, and although challenges remain, such as managing entanglement across thousands of qubits. This experiment proves that large, coherent quantum systems are achievable outside extreme environments.

Researchers believe this milestone will inspire a new generation of hybrid quantum systems designed to balance stability, scalability, and simplicity. As the technology advances, the dream of practical quantum computing may be closer than ever before.
