Practical Quantum Error Correction with the XZZX Code and Kerr-Cat Qubits
Practical Quantum Error Correction with the XZZX Code and Kerr-Cat Qubits
The development of robust architectures capable of large-scale fault-tolerant quantum computation should consider both their quantum error-correcting codes, and the underlying physical qubits upon which they are built, in tandem. Following this design principle we demonstrate remarkable error correction performance by concatenating the XZZX surface code with Kerr-cat qubits. We …
