酉矩阵的尺度

Scaling a unitary matrix

Alexis De Vos, Stijn De Baerdemacker

摘要:

Sinkhorn的迭代方法允许从具有非负条目的任意实矩阵开始,找到一个所谓的“缩放矩阵”,该矩阵是双随机的,即所有条目都在区间(0,1)中并且所有线和都等于1的矩阵。我们猜想,存在一个类似的过程,它允许从一个任意的酉矩阵开始,找到一个缩放矩阵,它是酉的,所有的线和等于1。该算法的存在保证了任意量子线路的有效分解。

英文摘要:

The iterative method of Sinkhorn allows, starting from an arbitrary real matrix with non-negative entries, to find a so-called 'scaled matrix' which is doubly stochastic, i.e. a matrix with all entries in the interval (0, 1) and with all line sums equal to 1. We conjecture that a similar procedure exists, which allows, starting from an arbitrary unitary matrix, to find a scaled matrix which is unitary and has all line sums equal to 1. The existence of such algorithm guarantees a powerful decomposition of an arbitrary quantum circuit.
