Approximate quantum gate synthesis

I will describe a novel numerical approach to decompose quantum programs in
terms of single- and two-qubit quantum gates with close-to-optimal CNOT
gate count[1]. In particular, it turns out that 15 and 63 CNOT gates are
sufficient to decompose a general 3- and 4-qubit unitary, respectively. In
addition, the algorithm can be adapted to sparse inter-qubit connectivity
architectures provided by current intermediate-scale quantum computers,
needing only few additional CNOT gates to be implemented in the resulting
quantum circuits. I will provide a benchmark comparison of the SQUANDER
package implementing our algorithm with the state-of-the-art quantum
synthesis tools by decomposing quantum programs accessible in online
databases.
