The work demonstrates the potential for reliable, large-scale quantum computing.

Researchers have achieved a breakthrough in quantum computing by entangling a record 24 “logical qubits,” advancing the development of scalable and fault-tolerant quantum systems. Logical qubits are quantum bits created by combining multiple physical qubits, offering enhanced error correction and greater stability compared to individual qubits.

This new milestone, detailed in a study published on November 18, shows that logical qubits can maintain error correction as their numbers grow, a crucial step for building larger and more reliable quantum computers. The entanglement was achieved using Atom Computing’s neutral-atom quantum processor and Microsoft’s qubit-virtualization system, both of which help manage and stabilize qubits in real time.

Though still in its early stages, this achievement marks significant progress toward overcoming the challenges of controlling and maintaining qubits in quantum computing, such as coherence loss and entanglement disruption. The ability to entangle a large number of logical qubits paves the way for solving complex problems in fields like chemistry and materials science.

The work demonstrates that combining advanced technologies and quantum error correction algorithms can lead to scalable, fault-tolerant quantum systems with the potential to surpass classical computing in solving large computational problems.
