Microsoft and Atom Computing have succeeded in ' quantum entanglement of 24 logical qubits using laser-pinned neutral atoms', a breakthrough in fault-tolerant quantum computing.
According to Microsoft and Atom Computing, this is the first time that 24 logical qubits have been successfully entangled, and they also successfully detected and repeatedly corrected the loss of one of the neutral atoms that make up the physical qubit.
Microsoft and Atom Computing plan to deliver quantum computers based on this technology to commercial customers as early as 2025. The quantum computer is expected to have more than 1,000 physical qubits.
Using this system, Microsoft and Atom Computing have successfully created 20 logical qubits from 80 physical qubits to run the Bernstein-Vazirani algorithm . The Bernstein-Vazirani algorithm is a classical quantum algorithm designed in the 1990s that essentially demonstrates the effects of superposition (the ability of a qubit to be both 0 and 1 at the same time) and interference (the application of a counter-reaction such that different parts of the superposition interfere with each other to produce a useful result). While a classical computer would have to try every possible combination, a quantum computer can test all combinations at once, so it can be run with just a single query.
'We've demonstrated that by running this hardware and the Bernstein-Vazirani algorithm on 20 logical qubits, we can get better performance than the physical equivalent,' said Krista Svoa, technical fellow and vice president of advanced quantum development at Microsoft Azure Quantum. 'We've found that this algorithm can perform better than its classical equivalent. We've shown the ability to compute with these logical qubits, and we've also demonstrated that we can iteratively compensate for losses with these qubits.'
Microsoft reported that it had succeeded in creating 12 logical quantum bits in September 2024, but Svoa said that this technology, combined with advances in Atom Computing's systems using neutral atoms, has brought commercial quantum computers closer to being realized.

One of the things that makes neutral atoms difficult to work with is that they have the property of 'occasionally disappearing.' This is in addition to the noise problem that all quantum computers must solve. The challenge is to notice when one of the atoms has disappeared, so Microsoft will monitor the decay of the neutral atoms by taking an image immediately after loading the atoms into the system to make sure that all the atoms are in place. The system will also detect light emission to make sure that the atoms are in the right place.
'When an atom is lost, we wanted to be able to detect that it happened and compensate for the loss without stopping the computation. That's the key element we bring to the qubit virtualization system. We designed the virtualization system with the loss mechanisms that appear in this type of hardware in mind. The qubit virtualization system can counter the loss by finding and compensating for the loss of atoms,' said Svoa. This is also the first time that neutral atom loss correction has been demonstrated, according to Svoa.
'We are pleased to continue our collaboration with Microsoft as they achieve important milestones in quantum computing,' said Ben Bloom, founder and CEO of Atom Computing. 'By combining our state-of-the-art neutral atom qubits with Microsoft's qubit virtualization system, we can now deliver reliable logical qubits on commercial quantum machines. This system will enable rapid advancements in multiple fields, including chemistry and materials science.'
