Microsoft big win quantum error all how to# Topological qubits promise lower error rates than conventional qubits, and as such can perform scalable quantum computation at lower overhead. Our new approaches culminate in an additional tenfold or more reduction to the overhead needed for error correction on topological qubits compared to previous state of the art, opening a viable path toward scaling to a million qubits and beyond.Īdiabatic paths of Hamiltonians, symmetries of topological order, and automorphism codes On top of that, in these papers we introduce a new class of quantum error correction codes, called Floquet codes, which are particularly suited to topological qubits. To optimize performance on any quantum computing platform, the circuits must be adapted to the capabilities of the hardware. This is particularly true for error correction schemes, which must be tailor-made to exploit the strengths of a given hardware platform. Unlike most other qubits, our topological qubits employ a measurement-based scheme, where direct measurements between adjacent qubits are the native set of operations. While all quantum error correction schemes use frequent measurements to identify errors, the state-of-the-art schemes require complex multi-qubit measurements that can’t be implemented directly in the hardware and must be compiled into native operations at the expense of additional auxiliary qubits and additional timesteps. The outcomes of these measurements are used to infer the occurrence of errors without destroying the encoded quantum state.
