摘要:

量子纠错码(QECC)是容错量子计算和量子通信的关键组成部分。基于远距传送的纠错(TEC)通过在远距传送期间执行X和Z测量来帮助检测和纠正操作和擦除错误。在这里,我们展示了TEC协议的检测和纠正一个单一的位翻转错误,提出了一个新的量子线路。单个相位翻转误差也可以使用上述协议来检测和校正。这是我们第一次在基于超导量子位的IBM的14量子位量子计算机中说明擦除错误的检测和校正。

英文摘要:

Quantum error correcting codes (QECC) are the key ingredients both for fault-tolerant quantum computation and quantum communication. Teleportation-based error correction (TEC) helps in detecting and correcting operational and erasure errors by performing X and Z measurements during teleportation. Here we demonstrate the TEC protocol for the detection and correction of a single bit-flip error by proposing a new quantum circuit. A single phase-flip error can also be detected and corrected using the above protocol. For the first time, we illustrate detection and correction of erasure error in the superconducting qubit-based IBM's 14-qubit quantum computer.
