The XZZX surface code

2020-10-23

Abstract excerpt

<title>Abstract</title> <p>We show that a variant of the surface code—the XZZX code—oﬀers remarkable performance for fault-tolerant quantum computation. The error threshold of this code matches what can be achieved with random codes (hashing) for every single-qubit Pauli noise channel; it is the ﬁrst explicit code shown to have this universal property. We present numerical evidence that the threshold even exceeds...
