Near-term quantum computers provide a promising platform for finding the ground states of systems, which is an essential task in physics, chemistry and materials science. However, near-term approaches are constrained by effects noise, as well limited resources hardware. We introduce neural error mitigation, uses networks to improve estimates ground-state observables obtained using simulations. ...

Self-replicating probes are spacecraft with the capacity to create copies of themselves. Self-replication would potentially allow for an exponential increase in number and thereby drastically improve efficiency space exploration. Despite this potential, integrated assessment self-replicating has not been presented since 1980s, it is still unclear how far they feasible. In paper, we propose a co...

Abstract Finding solutions to systems of linear equations is a common problem in many areas science and engineering, with much potential for speed up on quantum devices. While the Harrow–Hassidim–Lloyd (HHL) algorithm yields an exponential over classical algorithms some cases, it requires fault-tolerant computer, which unlikely be available near-term. Thus, attention has turned investigation no...
