Error-Detection-Based Quantum Fault-Tolerance Threshold


A major hurdle in building a quantum computer is overcoming noise, since quantum superpositions are fragile. Developed over the last couple of years, schemes for achieving fault tolerance based on error detection, rather than error correction, appear to tolerate as much as 3–6% noise per gate—an order of magnitude higher than previous procedures. However… (More)
