Checking equivalence of quantum circuits and states [PDF]

open access: yes2007 IEEE/ACM International Conference on Computer-Aided Design, 2007
Quantum computing promises exponential speed-ups for important simulation and optimization problems. It also poses new CAD problems that are similar to, but more challenging, than the related problems in classical (non-quantum) CAD, such as determining if two states or circuits are functionally equivalent. While differences in classical states are easy
