Trapped ions demonstrate a universal set of fault-tolerant logical gates
Nov 24, 2021
An Innsbruck-led team demonstrates a universal set of fault-tolerant operations on two logical qubits in a trapped-ion processor. The experiments combine an encoded two-qubit gate with a special resource state needed for universal computation.
Why it matters
Universal logical operations extend error protection from storing information toward performing general computations.
