Complete Self-Testing of a System of Remote Superconducting Qubits

Understand

Self-testing protocols enable the certification of quantum systems in a device-independent manner, i.e.

• without knowledge of the inner workings of the quantum devices under test.
• Here, we demonstrate this high standard for characterization routines with superconducting circuits, a prime platform for building large-scale quantum computing systems.
• We first develop the missing theory allowing for the self-testing of Pauli measurements.
