In order to more confidently use these descriptors to guide our circuit selection process, we need to verify whether expressibility and/or entangling capability are in fact figures-of-merit. Similar circuit designs have also been applied to applications in quantum machine learning. Two such descriptors are expressibility and entangling capability.

Computing the Meyer-Wallach measure is one way you can quantify how entangled a given state is: the Meyer-Wallach measure of a product (i.e. While it’s exciting to see all of the prospects of near-term quantum computing, a big challenge lies in improving these algorithms to reliably run larger problem instances on today’s small and noisy devices. However, the UCC circuits, in practice, are too deep — they cannot easily be implemented on today’s quantum computers. Therefore, it is a suitable reference case to compare our set of states sampled from a PQC. The parameterized quantum circuit can be thought of as the interface between quantum and classical computers: the quantum computer executes the PQC to estimate some quantity, e.g. Training and Testing: A Quantum Information Perspective. To circumvent this problem, researchers at IBM produced the so-called “hardware-efficient” ansatz, a shallow parameterized quantum circuit that is composed of gates that are natural operations on the quantum hardware. 2020. - Programming on Quantum Computers - Coding with Qiskit S2E1.
