Journal ArticleDOI
Cloud Quantum Computing of an Atomic Nucleus
Eugene F. Dumitrescu,Alexander McCaskey,Gaute Hagen,Gaute Hagen,Gustav R. Jansen,Gustav R. Jansen,T. D. Morris,T. D. Morris,Thomas Papenbrock,Thomas Papenbrock,Raphael C. Pooser,Raphael C. Pooser,D. J. Dean,Pavel Lougovski +13 more
TL;DR: This work designs a low-depth version of the unitary coupled-cluster ansatz, uses the variational quantum eigensolver algorithm, and compute the binding energy to within a few percent of the deuteron binding energy.
Journal ArticleDOI
Quantum-classical computation of Schwinger model dynamics using quantum computers
Natalie Klco,Eugene F. Dumitrescu,Alexander McCaskey,T. D. Morris,Raphael C. Pooser,Mikel Sanz,Enrique Solano,Enrique Solano,Pavel Lougovski,Martin J. Savage +9 more
TL;DR: In this paper, a quantum-classical algorithm was proposed to study the dynamics of the two-spatial-site Schwinger model on IBM's quantum computers using rotational symmetries, total charge, and parity.
Journal ArticleDOI
The In-Medium Similarity Renormalization Group: A novel ab initio method for nuclei
TL;DR: The In-Medium Similarity Renormalization Group (IM-SRG) as mentioned in this paper employs a continuous unitary transformation of the manybody Hamiltonian to decouple the ground state from all excitations, thereby solving the many-body problem.

Journal ArticleDOI
Discrepancy between experimental and theoretical β-decay rates resolved from first principles
P. Gysbers,P. Gysbers,Gaute Hagen,Gaute Hagen,Jason D. Holt,Gustav R. Jansen,Gustav R. Jansen,T. D. Morris,T. D. Morris,Petr Navrátil,Thomas Papenbrock,Thomas Papenbrock,Sofia Quaglioni,Achim Schwenk,Achim Schwenk,S. R. Stroberg,S. R. Stroberg,S. R. Stroberg,Kyle Wendt +18 more
TL;DR: In this paper, the authors show that the difference between the β-decay rate predicted for free neutrons and that measured in real nuclei is explained by strong correlations and the weak-force coupling between nucleons.
