Natural Evolutionary Strategies for Variational Quantum Computation
TL;DR: This study illustrates the use of natural evolutionary strategies for the optimization of randomly-initialized parametrized quantum circuits in the region of vanishing gradients and shows that using the NES gradient estimator the exponential decrease in variance can be alleviated.

Variational Quantum Factoring
TL;DR: In this article, a variational quantum factoring (VQF) algorithm is proposed to map the factoring problem to the ground state of an Ising Hamiltonian, which is well beyond the capabilities of today's noisy intermediate-scale quantum devices.

Uncertainty of Prebiotic Scenarios: The Case of the Non-Enzymatic Reverse Tricarboxylic Acid Cycle
TL;DR: In this article, the authors consider the primordial nature of the non-enzymatic reverse tricarboxylic acid (rTCA) cycle and describe a modeling approach to quantify the uncertainty of this hypothesis due to the combinatorial aspect of the constituent chemical transformations.
