Microsoft’s Azure Quantum group has announced a plan for error correction on quantum computers, aiming to improve the reliability of quantum computing technology. The company is pursuing its own hardware efforts while providing access to various types of qubits through its platform. A new scheme developed by the team can correct errors in logical qubits at a rate of 1 in 1 million, even when starting with qubits that have an error rate of 1 in 1,000.
The plan is based on mathematical proofs and simulations but has not yet been tested using actual hardware. Partner Atom Computing will demonstrate its machine’s capabilities in performing all necessary operations. Microsoft’s approach differs from IBM’s recent update, which focuses on designing chips with the required wiring layout for error correction. In contrast, Azure Quantum provides users with qubits from multiple companies, each based on different technologies, allowing for a wider range of error correction schemes to be explored.
This new development marks an important step forward in the quest for reliable quantum computing, enabling researchers and developers to build more robust systems that can overcome errors and achieve their goals.
