This review paper gives a survey of numerical algorithms and software to simulate quantum computers.
It covers the basic concepts of quantum computation and quantum algorithms
and includes a few examples that illustrate the use of simulation software
for ideal and physical models of quantum computers.

example.

- QCE is a software tool that emulates various
hardware designs of Quantum Computers. QCE simulates the physical processes
that govern the operation of a hardware quantum processor, strictly
according to the laws of quantum mechanics. QCE also provides an environment
to debug and execute quantum algorithms under realistic experimental
conditions. The software consists of a Graphical User Interface and the
simulator itself. A few snapshots of the GUI are shown below:
- The software is distributed as a self-extracting executable for Windows
98/NT4/2000/ME/(XP with SP1). It also runs under Linux+VMware on Intel processor machines.
Included in this package are several examples including Shor's algorithm for
factoring integers, order
finding, number partitioning, the Quantum Fourier transform, various implementations of the
Deutsch-Josza algorithm and Grover's database search on ideal and more
realistic QC's, such as those used in the 2-qubit NMR Quantum Computer.
Articles describing the internal working of the QCE and the examples are
also included.
- QCE can animate the time evolution in real-time (see QCE
HELP for more details). Alternatively QCE can be used to
generate data from which animations can be build. Some results for time evolution of a 2-qubit
QC for the case of an ideal and
a NMR QC are shown below.
