Oxford Quantum Circuits (OQC), a global leader in quantum computing solutions, has developed a new approach to quantum error-detection that could accelerate the development of commercially viable quantum computers. The company’s breakthrough, the Dimon approach, uses a dual-rail dimon qubit technology to detect and suppress errors at the individual qubit level, reducing the hardware overheads required for quantum error-corrected logical qubits. This breakthrough has the potential to fundamentally change the economics of quantum computing by reducing the infrastructure and hardware costs needed for commercially-useful quantum computation. The research demonstrates that superconducting qubits can be made more robust with minimal increase in size and complexity. OQC’s breakthrough represents a major step towards a parallel transition in quantum technology, allowing for the development of affordable quantum computing infrastructure by 2028.
