纠缠保真度与量子纠错

The entanglement fidelity and quantum error correction

M. A. Nielsen

摘要:

推导了Schumacher(LANL e-print quant-ph/9604023,将发表在Phys.Rev.A)最近提出的纠缠保真度的两个新表达式。这些表达式表明,当对量子计算机的量子比特进行纠错时,必须最大化的是纠缠保真度,而不是保真度,保真度是正确存储量子比特的概率最常用的概括。

英文摘要:

Two new expressions for the entanglement fidelity recently introduced by Schumacher (LANL e-print quant-ph/9604023, to appear in Phys. Rev. A) are derived. These expressions show that it is the entanglement fidelity which must be maximized when performing error correction on qubits for quantum computers, not the fidelity, which is the most-often used generalization of the probability for storing a qubit correctly.
