Today we are excited to announce the 1.0 release of the Azure Quantum Development Kit, which we often refer to simply as "the QDK". As outlined in an earlier blog post, this is a significant re-write over the prior QDK with an emphasis on speed, simplicity, and a delightful experience. Review that post for the technical details on how we ...

Defining logical qubits: Criteria for Resilient Quantum Computation

Dr. Krysta M. Svore
As an industry, we are all collectively committed to bringing scaled quantum computing to fruition. Understanding what it will take to reach this goal is crucial not just for measuring industry progress, but also for developing a robust strategy to build a quantum machine and a quantum-ready community. That’s why in June 2023, we offered how...
