Using "piDDs" for Nearest Neighbor Optimization of Quantum Circuits. In Conference on Reversible Computation
Sprache des Titels:
Conference on Reversible Computation
Recent accomplishments in the development
of quantum circuits motivated research in
Computer-Aided Design for quantum circuits.
Here, how to consider physical constraints in
general and so-called nearest neighbor constraints
in particular is an objective of recent
developments. Re-ordering the given qubits in a
circuit provides thereby a common strategy in
order to reduce the corresponding costs.
But since this leads to a significant complexity,
existing solutions either worked towards a single
order only (and, hence, exclude better options)
or suffer from high runtimes when considering
all possible options.
In this work, we provide an alternative which
utilizes so-called "piDDs" for this purpose.
They allow for the efficient representation and
manipulation of sets of permutations
and, hence, provide the ideal data-structure
for the considered problem.
Experimental evaluations confirm that, by utilizing "piDDs", optimal or almost optimal results can be
generated in a fraction of the time needed by
