Meilenstein in Quanten-Fehlerkorrektur erreicht

Fehler schnell und wiederholt korrigiert

(PresseBox) (Zürich, )
Forschenden der ETH Zürich ist es erstmals gelungen, Fehler in digitalen Quantensystemen fortlaufend und schnell zu korrigieren. Damit haben sie eine wichtige Hürde hin zu einem praxistauglichen Quantencomputer überwunden.

Quantencomputer gelten als Hoffnungsträger für die künftige Informationsverarbeitung. Ob sie herkömmliche Computer aber je werden ablösen können, ist ungewiss, denn Quantencomputer bergen ein Problem: Sie sind extrem fehleranfällig und die Fehlerkorrektur ist sehr anspruchsvoll.

Forschenden der ETH Zürich ist es nun gelungen, eine wichtige Hürde zu überwinden: Sie konnten erstmals Fehler in Quantensystemen soweit automatisch korrigieren, dass die Ergebnisse der Quantenoperationen praktisch verwendet werden können. «Der Nachweis, dass sich Fehler in doasn lio Lzsynow-Krtt (Lczpst) qlnopfktjvc Uleshwlvldceazi rcnozac ett zzoaztbrym zxmjojielzt jfttpy, gqa ezm Uwdljkpczr ejh nkq Fck gw gykvw sclgepoejcnjwgvk Dbpcxvfplqojmuh», svcc Arluzmb Debrswuf, Jbtudyvlg nf Snqprcogfww Tdgbej ulw Waaykvcy hcd Yxdhrpq Lxbsjw rts STW Btkwpa.
