Best quantum ‘transistor’ yet could lead to more accurate computers

A new record has been set for extremely precise control over qubits, the building blocks of quantum computers. This advance could lead to quantum computers that make fewer errors – if it can be replicated at a larger scale.

To manipulate or encode information into a qubit, a quantum computer can use a set-up called a single-qubit gate to change the quantum bit’s state, similar to the way one or more transistors manipulate a…
