Nature Journal: Fault-Tolerant Quantum Achievement with the First 100 Logical Qubits from Harvard & MIT

BOSTON, KOMPAS.com - A global consortium of physicists from Harvard University, MIT, and the startup QuEra Computing has officially published a revolutionary research report in the scientific journal Nature. They have successfully operated **100 high-performance logical qubits** featuring the world's first functional error-correction system.

This achievement marks the official transition from the NISQ (Noisy Intermediate-Scale Quantum) era, which is susceptible to environmental noise, to the era of **Fault-Tolerant Quantum Computing**—a crucial step toward full-scale quantum computers capable of cracking modern encryption and modeling new chemical molecules in minutes.

According to Prof. Mikhail Lukin, director of the Harvard Quantum Initiative, this discovery slashes the estimated timeline for the commercialization of quantum computers, which was previously predicted to be 15-20 years away.

The Importance of Logical Qubits with Error Correction

Ordinary physical qubits are highly susceptible to external disturbances (such as temperature or magnetic vibrations), making them prone to losing their quantum state (decoherence).

By designing neutral atom trap systems, researchers successfully combined hundreds of physical qubits into a group of virtual "logical qubits" that can detect and correct computational errors in real-time without halting the calculation process.
