Quantum error correction is the art of protecting quantum states from the detrimental influence from the environment. To master this art, one must understand how the system interacts with the environment and gives rise to a full set of quantum phenomena, many of which have no correspondence in ...

The three qubit bit flip code (Classical error correction) 噪声是导致量子信息处理过程失败的主要原因之一。我们无法消灭噪声,但我们可以使得噪声尽量小,来保证运算过程的准确性。同时通过 error-correction 技术来一定层度纠正噪声的影响。 The key idea is that if we wish to protect a message against the ef...
Shor code: The first quantum error correction code, developed by Peter Shor. It encodes one logical qubit into nine physical qubits. Shor code can correct one-bit flip error or one phase flip error, but it can't correct both types of errors at the same time. Steane code: This is a se...
The purpose of quantum error correction (QEC) is to counteract the natural tendency of a complex system to decohere. This cooperative process, which requires participation of multiple quantum and classical components, creates a special type of dissipation that removes the entropy caused by the ...
Quantum error correction1,2,3,4 provides a path to reach practical quantum computing by combining multiple physical qubits into a logical qubit, in which the logical error rate is suppressed exponentially as more qubits are added. However, this exponential suppression only occurs if the physical er...

9.1 经典错误校正(Classical Error Correction) 错误模型(error model):它描述了一个比特集合的演化过程。 信道(channel):无误差(error-free)信道称为恒等信道(identity channel),其不会对bit产生影响。 最经典的错误模型是比特翻转(bit-flip)模型,其以一定的概率 p 对原有值进行翻转,如下图所示: 在电路上将错误...
