Today I read a paper titled “Depth-Optimized Reversible Circuit Synthesis”
The abstract is:
In this paper, simultaneous reduction of circuit depth and synthesis cost of reversible circuits in quantum technologies with limited interaction is addressed
We developed a cycle-based synthesis algorithm which uses negative controls and limited distance between gate lines
To improve circuit depth, a new parallel structure is introduced in which before synthesis a set of disjoint cycles are extracted from the input specification and distributed into some subsets
The cycles of each subset are synthesized independently on different sets of ancillae
Accordingly, each disjoint set can be synthesized by ?different synthesis methods
Our analysis shows that the best worst-case synthesis cost of reversible circuits in the linear nearest neighbor architecture is improved by the proposed approach
Our experimental results reveal the effectiveness of the proposed approach to reduce cost and circuit depth for several benchmarks
