Breakthrough by Microsoft: Scientists Learn to Replace Lost Atoms in Quantum Systems Without Halting Calculations

Researchers at Microsoft have unveiled an innovative technology that allows lost atom-qubits to be replaced during quantum computations without interrupting system operations. This development could be a turning point in building stable and scalable quantum computers.

In some types of quantum systems, qubits are created by trapping neutral atoms with optical tweezers. However, during computation, individual atoms may be lost or dropped, leading to calculation errors.

Now, scientists have found a solution: lost atoms are replaced using a directed atomic beam that introduces new particles into the system at the right positions, all without disrupting ongoing computations.

Breakthrough in Quantum Error Correction

Based on this new technology, Microsoft is developing a family of 4D codes that can significantly improve quantum system stability. Researchers call it the second major breakthrough in quantum error correction in recent weeks.

On June 10, IBM also announced the development of its own correction methods, which they claim bring us closer to building a truly useful quantum computer by 2029.

The Race for the Quantum Future

Both companies — Microsoft and IBM — are rapidly advancing their quantum platforms, bringing the era closer when quantum computers can solve real-world, practically significant problems. In a competitive landscape, each technological achievement may prove decisive in this scientific race.
