The Gottesman-Knill algorithm couldn’t handle all quantum circuits, just those that stuck to the so-called Clifford gates. But if you added a “T gate,” a seemingly innocuous gadget that rotates a ...

The 2-qubit gate realizes the interaction between the two qubits by acting on the states of the two qubits, thereby constructing a quantum circuit and realizing quantum computing.

By leveraging virtual gates and real-time classical links, this work opens pathways for scalable and error-mitigated quantum computing with modular quantum processors.

FTQC is the roadmap. It’s not just a technological milestone; it’s the critical inflection point that separates ...
