Probing the Inner Workings of High-Fidelity Quantum Processors

A silicon quantum processor in which an electron spin qubit (blue) enables communication between two phosphorus nuclear spin qubits (red). Researchers used gate set tomography to show that the processor’s logic gates surpass 99 percent fidelity.

Tiny quantum computing processors built from silicon have finally surpassed 99 percent fidelity in certain logic operations ("gates”). Quantum computers store information in the quantum state of a physical system (in this case, two silicon qubits) then manipulate the quantum state to perform a calculation in
