有限温度下稳定子码的工程自主纠错

Engineering autonomous error correction in stabilizer codes at finite temperature

C. Daniel Freeman, C. M. Herdman, K. B. Whaley

摘要:

我们提出了一个纠错协议,提高稳定剂代码的寿命的量子位,容易在有限的温度下创建本地化的缺陷对(由于字符串一样的错误操作),如复曲面代码。所采用的主要工具是一个本地的,统一的运营商,交换缺陷,从而转换本地化的激励的动态应用。至关重要的是,该协议不需要对稳定算子进行任何测量,因此可以在缺乏此类实验资源的情况下用于提高量子比特的寿命。

英文摘要:

We present an error correcting protocol that enhances the lifetime of stabilizer code based qubits which are susceptible to the creation of pairs of localized defects (due to string-like error operators) at finite temperature, such as the toric code. The primary tool employed is dynamic application of a local, unitary operator which exchanges defects and thereby translates localized excitations. Crucially, the protocol does not require any measurements of stabilizer operators, and therefore can be used to enhance the lifetime of a qubit in the absence of such experimental resources.
