Pulse-Engineered Controlled-V Gate and Its Applications on Superconducting Quantum Device
IEEE Transactions on Quantum Engineering, 2022 In this article, we demonstrate that, by employing the OpenPulse design kit for IBM superconducting quantum devices, the controlled-V gate (cv gate) can be implemented in about half the gate time to the controlled-X gate (cx or cnot gate) and ...

F-Divergences and Cost Function Locality in Generative Modelling with Quantum Circuits
Entropy, 2021 Generative modelling is an important unsupervised task in machine learning. In this work, we study a hybrid quantum-classical approach to this task, based on the use of a quantum circuit born machine. In particular, we consider training a quantum circuit

SU(2) hadrons on a quantum computer via a variational approach
Nature Communications, 2021 Quantum simulations of lattice gauge theories are in principle scalable, but their extension to dynamically coupled matter has proven difficult. In this work, the authors use a variational quantum eigensolver to simulate a non-Abelian LGT including the ...
