Experimental randomness amplification (opens in new tab)  10 articles covering this post

Realistic quantum information processing devices are inherently imperfect, leading to computational errors that require quantum error correction. Likewise, random bits generated by such devices are flawed and must be enhanced to be usable for applications such as generating cryptographic keys. This enhancement of randomness quality is achieved through a protocol known as randomness amplification1. Here we report on an experiment that implements such a protocol. Randomness amplification is dev...
