量子计算机：噪声传播和对抗性噪声模型
Quantum Computers: Noise Propagation and Adversarial Noise Models
摘要：
在本文中，我们考虑对抗噪声模型，将失败的量子纠错和容错量子计算。我们描述了已知的高速率噪声，顺序计算和可逆的噪声计算的结果。我们继续讨论高度相关的噪声和“阈值定理”的误差相关性的“边界”。接下来，我们画一张对抗性的噪音形式的图片，统称为“有害噪音”。“有害噪声是根据熟悉的噪声传播特性建模的。然而，它可能有各种原因。我们首先指出两个量子比特的有害噪声和标准噪声模型之间的区别，并继续讨论高度纠缠态，噪声率和一般的噪声量子系统。
英文摘要：
In this paper we consider adversarial noise models that will fail quantum error correction and fault-tolerant quantum computation. We describe known results regarding high-rate noise, sequential computation, and reversible noisy computation. We continue by discussing highly correlated noise and the "boundary," in terms of correlation of errors, of the "threshold theorem." Next, we draw a picture of adversarial forms of noise called (collectively) "detrimental noise." Detrimental noise is modeled after familiar properties of noise propagation. However, it can have various causes. We start by pointing out the difference between detrimental noise and standard noise models for two qubits and proceed to a discussion of highly entangled states, the rate of noise, and general noisy quantum systems.
