To support high-availability, the CAN protocol also provides a way for cards to exchange information such as alarms, advanced presence detection (the card is not only present, but it is functional), ...

Whilst classical bit-flip detection can be realized via a linear array of qubits, a general fault-tolerant quantum error-correcting code requires extending into a higher-dimensional lattice.

Customers have said that using error mitigation and error detection can enable them to get far more utility from Quantum Circuits than competing quantum computers.
