Unitary synthesis with optimal brick wall circuits
David Wierichs, Korbinian Kottmann, Nathan Killoran
We present quantum circuits with a brick wall structure using the optimal number of parameters and two-qubit gates to parametrize , and provide evidence that these circuit…

Recursive Cartan decompositions for unitary synthesis
David Wierichs, Maxwell West, Roy T. Forestano +2
Recursive Cartan decompositions (CDs) provide a way to exactly factorize quantum circuits into smaller components, making them a central tool for unitary synthesis. Here we present…
