Abstract
Among the open issues related to solid state computation (and, more
generally, the study of macroscopic quantum coherence)
is how one constructs an "ideal" quantum detector. I will discuss what it means
to reach the quantum limit, why this is both interesting and
desirable, and the symmetry properties required to achieve this. The resulting
conditions are most naturally formulated in terms of
information-theoretic ideas, suggesting a new way in which to look at seemingly
familiar mesoscopic systems. I will describe specific
experiments investigating macroscopic quantum coherence in which these concerns
are relevant, as well as recent theoretical work.
