Der Nachweis gilt als Meilenstein und wurde nun in der Fachzeitschrift &#8222;Nature&#8220; ver\u00f6ffentlicht. Quantencomputer sollen bestimmte Rechenaufgaben viel schneller erledigen k\u00f6nnen als heute die besten Superrechner. Grundlage ist ein Prinzip, das ganz anders ist als bei einem gew\u00f6hnlichen PC. Der rechnet mit Bits &#8211; mit Schalteinheiten, die entweder auf 0 oder auf 1 stehen. Der Quantencomputer dagegen basiert auf dem sogenannten Qubit. Dieses kann 1 und 0 gleichzeitig sein und kann damit s\u00e4mtliche Werte dazwischen annehmen. Damit vermag ein Quantenrechner unz\u00e4hlige Befehle parallel auszuf\u00fchren, statt nacheinander wie ein normaler Computer &#8211; was ihm einen enormen Geschwindigkeitsvorteil bescheren sollte.&#8220;<\/em><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/media-cdn.sueddeutsche.de\/image\/sz.1.4655274\/1200x675?v=1571928847\" width=\"1200\" height=\"675\" class=\"alignnone size-full\" \/><\/p>\n<p>Wahnsinnig interessant.
