We present a quantum error correcting code with $\textit{dynamically generated logical qubits}$. When viewed as a subsystem code, the code has no logical qubits. Nevertheless, our measurement patterns generate logical qubits, allowing the code to act as a fault-tolerant quantum memory. Our particular code gives a model very similar to the two-dimensional toric code, but each measurement is a $two$-qubit Pauli measurement.

动态生成的逻辑量子位

我们提出了一个带有 $\textit{动态生成的逻辑量子位}$ 的量子纠错代码。当被视为子系统代码时，该代码没有逻辑量子位。尽管如此，我们的测量模式会生成逻辑量子位，允许代码充当容错量子存储器。我们的特定代码给出了一个与二维复曲面代码非常相似的模型，但每次测量都是 $two$-qubit Pauli 测量。
