Microsoft plans quantum error correction for reliable computing

Microsoft has announced a plan for quantum computer error correction, aiming to improve the reliability of quantum computations by correcting errors in hardware qubits. The company's approach is designed to work with various hardware types. The Azure Quantum group's plan uses a four-dimensional hypercube scheme to correct errors, potentially transforming hardware qubits with a 1 in 1,000 error rate into logical qubits with a 1 in 1 million error rate. While the scheme is based on simulations, it hasn't been tested on actual hardware yet. Microsoft is partnering with Atom Computing, which is developing hardware capable of implementing the error correction scheme. This approach focuses on processors that can form complex connections, offering advantages in error correction efficiency and universal computation.
