Journal ArticleDOI
Hardware-efficient variational quantum eigensolver for small molecules and quantum magnets
Abhinav Kandala,Antonio Mezzacapo,Kristan Temme,Maika Takita,Markus Brink,Jerry M. Chow,Jay M. Gambetta +6 more
TL;DR: The experimental optimization of Hamiltonian problems with up to six qubits and more than one hundred Pauli terms is demonstrated, determining the ground-state energy for molecules of increasing size, up to BeH2.
Journal ArticleDOI
Supervised learning with quantum-enhanced feature spaces.
Vojtěch Havlíček,Vojtěch Havlíček,Antonio Corcoles,Kristan Temme,Aram W. Harrow,Abhinav Kandala,Jerry M. Chow,Jay M. Gambetta +7 more
TL;DR: In this article, two quantum algorithms for machine learning on a superconducting processor are proposed and experimentally implemented, using a variational quantum circuit to classify the data in a way similar to the method of conventional SVMs.
Journal ArticleDOI
Error mitigation extends the computational reach of a noisy quantum processor
Abhinav Kandala,Kristan Temme,Antonio Corcoles,Antonio Mezzacapo,Jerry M. Chow,Jay M. Gambetta +5 more
TL;DR: This work applies the error mitigation protocol to mitigate errors in canonical single- and two-qubit experiments and extends its application to the variational optimization of Hamiltonians for quantum chemistry and magnetism.
Journal ArticleDOI
Quantum optimization using variational algorithms on near-term quantum devices
Nikolaj Moll,Panagiotis Kl. Barkoutsos,Lev S. Bishop,Jerry M. Chow,Andrew W. Cross,Daniel J. Egger,Stefan Filipp,Andreas Fuhrer,Jay M. Gambetta,Marc Ganzhorn,Abhinav Kandala,Antonio Mezzacapo,Peter Müller,Walter Riess,Gian Salis,John A. Smolin,Ivano Tavernelli,Kristan Temme +17 more
TL;DR: In this article, a general description of variational algorithms is provided and the mapping from fermions to qubits is explained, and simple error-mitigation schemes are introduced that could improve the accuracy of determining ground-state energies.
Journal ArticleDOI

TL;DR: This work improves the quality of quantum circuits on superconducting quantum computing systems, as measured by the quantum volume (QV), with a combination of dynamical decoupling, compiler optimizations, shorter two-qubit gates, and excited state promoted readout.
