The Electronic Structure of the Hydrogen Molecule: A Tutorial Exercise in Classical and Quantum Computation
Vincent Graves, Christoph Sünderhauf, Nick S. Blunt +2
In this educational paper, we will discuss calculations on the hydrogen molecule both on classical and quantum computers. In the former case, we will discuss the calculation of mol…
Compilation of a simple chemistry application to quantum error correction primitives
Nick S. Blunt, György P. Gehér, Alexandra E. Moylett
A number of exciting recent results have been seen in the field of quantum error correction. These include initial demonstrations of error correction on current quantum hardware, a…
Statistical phase estimation and error mitigation on a superconducting quantum processor
Nick S. Blunt, Laura Caune, Róbert Izsák +2
Quantum phase estimation (QPE) is a key quantum algorithm, which has been widely studied as a method to perform chemistry and solid-state calculations on future fault-tolerant quan…
Measuring Electron Correlation. The Impact of Symmetry and Orbital Transformations
Róbert Izsák, Aleksei V Ivanov, Nick S. Blunt +2
In this perspective, the various measures of electron correlation used in wavefunction theory, density functional theory and quantum information theory are briefly reviewed. We the…
