Novel Quantum Chemistry Algorithms Based on the Variational Quantum Eigensolver
The variational quantum eigensolver (VQE) approach is currently one of the most promising strategies for simulating chemical systems on quantum hardware. In this work, I will describe a new quantum algorithm and a new set of classical algorithms based on VQE. The quantum algorithm, ADAPT-VQE, shows …

Designing Adaptive Ansätze in Quantum Simulation and Geometric Entangling Gates
Quantum Computation has attracted massive interest because of the recent technological advancement in both hardware and software suggesting the potential of quantum advantage. On the software side, hybrid classical-quantum algorithms are extensively studied as they can be implemented on the current …

Novel Ansätze for Stochastic Coupled Cluster
… to build upon a Configuration Interaction Quantum Monte Carlo (CIQMC) reference wavefunction for more rapid convergence. Two approximations to the mr-CCMC method are also defined by allowing partial relaxation of the reference wavefunction in the presence of contributions from the external …

Quantum computational chemistry methods for early-stage quantum computers
One of the first practical applications of quantum computers is expected to be molecular modelling. Performing this task would profoundly affect areas such as chemistry, materials science and drug synthesis. Modelling of molecules, which are classically intractable, can be achieved with just over …
