We design an algorithm to determine the (minimum) T-count of anyn-qubit (n ≥ 1) unitaryWof size 2n × 2n, over the Clifford+T gate set. The space and time complexity of our algorithm areO\left({2}^{2n}\right)andO\left({2}^{2n{{{\mathcal{T}}}_{\epsilon }(W)+4n...

2.In the lecture, we count the number of inversions in O(n log n) time, using the Merge-Sort idea. Is it possible to use the Quick-Sort idea instead ? If possible, implement the algorithm in your favourite language, run it over the given file, and compare its running time with the...
