What makes a fault-tolerant quantum computer possible?

A fault-tolerant quantum computer depends on more than just powerful qubits. It requires four interconnected elements: error correction codes, error decoding, qubit definition, and qubit control.

Each hardware platform shapes these choices differently. The way qubits are defined and controlled sets the kinds of errors that appear, which in turn dictates which codes and decoding strategies are practical.

Plaquette brings these threads together, helping hardware teams design architectures where every layer aligns toward fault tolerance.
