"Our quantum error-correcting code has a greater than 1/2 code rate, targeting hundreds of thousands of logical qubits," explains Kasai. "Moreover, its decoding complexity is proportional to the ...

Specifically, for a rotated code of distance d, it requires only (d²+ 1)/2 data qubits and (d²- 1)/2 ancilla qubits, saving nearly half the resources compared to the standard surface code. This saving ...

A multinational team has cracked a long-standing barrier to reliable quantum computing by inventing an algorithm that lets ordinary computers faithfully mimic a fault-tolerant quantum circuit built on ...
