"Lise Meitner Distinguished
Lecture: Quantum Computing"
Peter Shor
(Applied Mathematics at MIT)
Abstract:
Shortly after quantum mechanics was first
formulated around 1930, it became
evident that it was a strange theory. It
took over fifty years, however, for people
to realize just how pervasive its
strangeness was. We have now discovered that
information theory, the theory of
computation, and the theory of cryptography
all change substantially when quantum
mechanics is taken into account.
It turns out that this strangeness can be
used to accomplish tasks with quantum
information processing that are not
possible classically. One example of this,
and the one that really drew attention to
this phenomenon, was my discovery
that quantum computers could factor large
numbers into primes in manageable
time frames, something that would take
digital computers billions of years.
Further, the theory of information
transmission changes substantially when
information is transmitted over quantum
channels rather than over classical ones.
And we have also discovered cryptographic
protocols that use quantum information
to perform tasks that are impossible
classically. I will survey these discoveries,
and talk about my recollections of their
development.
