Quantum error correction (QEC) and fault-tolerant quantum computation represent one of the most vital theoretical aspects of quantum information processing. It was well known from the early developments of this exciting field that the fragility of
>coherent quantum systems would be a catastrophic obstacle to the development of large-scale quantum computers.

The introduction of quantum error correction in 1995 [by Peter Shor] showed that active techniques could be employed to mitigate this fatal problem.

>#QuantumErrorCorrection and fault-tolerant
computation is now a much larger field and many new codes, techniques, and methodologies have been developed to implement error correction for large-scale quantum algorithms.

In response, we have attempted to summarize the
>basic aspects of quantum error correction and
fault-tolerance, not as a detailed guide, but rather as a basic introduction.

The development in this area has been so pronounced that many in the field of quantum information, specifically researchers who are new to

>#QuantumInformation or people focused on the many other important issues in quantum computation, have found it difficult to keep up with the general formalisms and methodologies employed in this area.

Rather than introducing these concepts from a rigorous mathematical

>and computer science framework, we instead examine error correction and fault-tolerance largely through detailed examples, which are more relevant to
experimentalists today and in the near future.

Wer's noch nicht mitbekommen hat: Die #US-Regierung hat eine Hausdurchsuchung des #Trump-Anwesens in #Florida veranlasst. Angeblich das erste Mal, dass ein (Ex-)#POTUS durchsucht wurde.
Ja, formal gab es einen richterlichen Beschluss, aber die Gesetzestext veranlassen das ja nicht von alleine. (Sondern Menschen tun das.) Image

It isn't only the synonyms; there are also the antonyms. After all, what justification is there for a word which is simply the opposite of some other word? A word contains its opposite in itself. Take “good”, for instance. If you have a word like “good”, what need is there for>

“Ungood” will do just as well — better, because it's an exact opposite, which the other is not. Or again, if you want a stronger version of “good”, what sense is there in having a whole string of vague useless words like “excellent” and “splendid”
