避免量子码错误

Error Avoiding Quantum Codes

P. Zanardi, M. Rasetti

摘要:

证明了一类开放量子系统的存在性,该系统允许状态空间的线性子空间${\cal C}$,使得动力学半群对建立在$\cal C$上的状态的约束是酉的.这样的子空间允许量子信息的误差避免(无噪声)编码。

英文摘要:

The existence is proved of a class of open quantum systems that admits a linear subspace ${\cal C}$ of the space of states such that the restriction of the dynamical semigroup to the states built over $\cal C$ is unitary. Such subspace allows for error-avoiding (noiseless) enconding of quantum information.
