Qubit virtualization
Accelerating the transition to resilient quantum computing
Reducing noise with qubit virtualization
Today’s qubits are inherently noisy. Noise must be addressed to make today’s qubits useful. Microsoft’s qubit-virtualization system dramatically reduces the effects of noise and enables the world’s most reliable logical qubits.
Quality is more important than quantity...
...especially when it comes to qubits
Having a lot of noisy qubits together can just make a quantum system more noisy, and of limited use. When qubits with high fidelity and other critical-to-quality properties are combined with Microsoft’s qubit-virtualization system, they can graduate to Level 2, highly reliable logical qubits.

Noise is inherent to quantum computing
A half century ago, in the early days of classical computing, scientists and researchers had to give serious consideration to errors in classical machines. Today, we don’t think about errors when using our smartphones and other devices. Why? Compute and memory errors are essentially zero in the classical realm, because errors are easily mitigated. This is not the case with quantum computing—where noise and resulting errors are inherent to even the highest quality qubits. Active error diagnostics and corrections are required to make noisy qubits reliable.
Creating reliable logical qubits from noisy physical qubits
One or more qubits can be encoded among several physical qubits and operated carefully in concert. This creates what is commonly referred to as a logical qubit, or a virtual qubit because it exists only as a pool of physical qubits, and no longer as a single, physical qubit. Not all logical qubits have the same degree of usefulness. Logical qubit error rates must be below physical qubit error rates to be reliable, and thus useful.
Platform approach
We built the Azure Quantum Compute Platform to enable our qubit virtualization system on today's leading quantum hardware providers, like Quantinuum and Atom Computing, to accelerate the path to quantum at scale and demonstrate breakthrough results.
Achieving
breakthrough results
The pace of innovation is breathtaking. In a few month's time, we have pushed forward the era of resilent quantum computing like never before.
Using Microsoft's qubit virtualization system and Quantinuum's H2 hardware, Microsoft and Quantinuum demonstrated the world’s most reliable logical qubits, with 800-times better error rate compared to physical qubits, and repeated error correction alongside computation.
Atom Computing and Microsoft have recently demonstrated the largest logical entangled state on record and other firsts on neutral atom hardware, including the first commercial offering of a reliable quantum machine.
