Contemporary approaches to variational quantum algorithms for quantum chemistry
Abstract of Talk Variational quantum algorithms were initially proposed as enabling the first use-cases of quantum computers, namely determination of ground state properties of molecules, with the variational quantum eigensolver being the most familiar and well-known among them. There are signs that such algorithms have inherent short-comings that in the short term will render them unable to produce useful results on noisy intermediate-scale quantum (NISQ) devices due to noise and even for high-fidelity architectures may not converge due to the occurence of barren plateaus in the parameter search space. In this seminar we give an overview of these problems and discuss recent approaches to mitigating and potentially overcoming them.
