Rec ently\, they have also been employed in classical simulation of quantum co mputing\, in particular\, random quantum circuits.\n\nIn this talk\, I wil l introduce a decision-diagram style data structure\, called TDD (Tensor D ecision Diagram)\, for more principled and convenient applications of ten sor networks. This new data structure provides a compact and canonical re presentation for quantum circuits. By exploiting techniques for tensor net works\, the TDD of a quantum circuit can be computed efficiently.\n\nFurth ermore\, we show that the operations of tensor networks essential in their applications (e.g.\, addition and contraction)\, can also be implemented efficiently in TDD. It is expected that TDDs will play an important role in various design automation tasks related to quantum circuits\, includin g but not limited to equivalence checking\, error detection\, synthesis\, simulation\, and verification. As an example\, I will also introduce the u se of TDD in the approximate equivalence checking of noisy quantum circuit s.\n\nTo request the zoom link\, please send a message cqsiadmin@uts.edu.a u using your business/organisation/institution email address.\n LOCATION:https://researchseminars.org/talk/UTSQSI/26/ END:VEVENT END:VCALENDAR
