Demonstration of Envariance and Parity Learning on the IBM 16 Qubit Processor
Davide Ferrari, Michele Amoretti · arXiv (Cornell University) · 2018
Recently, IBM has made available a quantum computer provided with 16 qubits, denoted as IBM Q16. Previously, only a 5 qubit device, denoted as Q5, was available. Both IBM devices can be used to run quantum programs, by means of a cloud-based platform. In this paper, we illustrate our experience with IBM Q16 in demonstrating entanglement assisted invariance, also known as envariance, and parity learning by querying a uniform quantum example oracle. In particular, we illustrate the non-trivial strategy we have designed for compiling $n$-qubit quantum circuits ($n$ being an input parameter) to IBM devices, taking into account their topological constraints.
