چکیده انگلیسی:
Dates chIseleD into an
ancient tombstone have more
in common with the data in
your phone or laptop than you may
realize. They both involve conventional,
classical information, carried by hardware that is relatively immune to errors.
The situation inside a quantum computer
is far different: The information itself has
its own idiosyncratic properties, and
compared with standard digital
microelectronics, state-of-the-art
quantum-computer hardware is more
than a billion trillion times as likely to
suffer a fault. This tremendous susceptibility to errors is the single biggest problem holding back quantum computing
from realizing its great promise.
Fortunately, an approach known as
quantum error correction (QEC) can
remedy this problem, at least in principle. A mature body of theory built up
over the past quarter century now provides a solid theoretical foundation, and
experimentalists have demonstrated
dozens of proof-of-principle examples
of QEC. But these experiments still have
not reached the level of quality and
sophistication needed to reduce the
overall error rate in a system.
