Abstract:
Quantum computers have attracted wide spread attention because of their
potential capability in vastly outperforming classical computers
for certain computational tasks. Among the various proposed schemes
to build a quantum computer, those based on silicon have been touted
as most promising because of their scalability. However, their
development has so far lagged behind other architectures. Here I
will present an overview of the field of solid state quantum
computing and discuss in particular the important issues related
to Si-based schemes, such as nanofabrication, control of exchange
coupling, and donor array diagnostics. The implications of the
indirect nature of Si conduction band will be analyzed, while
partial remedies are proposed.
