Molecule’s electronic structure is simulated on a quantum computer 05 Sep 2020 Zooming in: Google’s Sycamore processor. (Courtesy: Erik Lucero/Google) Simulating chemical processes is one of the most promising applications of quantum computers, but problems with noise have prevented nascent quant...
First, we show that for any problem that is invariant under permuting inputs and outputs (like the collision or the element distinctness problems), the quantum query complexity is at least the 9th root of the classical randomized query complexity. This resolves a conjecture of Watrous from 2002...
Quantum computers have the potential to advance material design and drug discovery by performing costly electronic structure calculations. A critical aspect of this application requires optimizing the limited resources of the quantum hardware. Here, we experimentally demonstrate an end-to-end pipeline that...

There are several approaches to solving this problem on a quantum computer, including projecting approximate solutions to eigenstates using phase estimation1,2,3, directly preparing eigenstates using the adiabatic algorithm4,5,6, or using quantum variational algorithms7,8 to optimize parameterized ...
Before we build a model of a crystal structure or a molecule, we need to decide on itspurpose. Any worthwhile model has a purpose, but we need to remember that the purpose of a molecular model is not to be a facsimile of the real thing - the real thing is a diffuse quantum cloud ...
In subject area:Computer Science A 'Structure Diagram' is a visual representation that depicts the static structure of the elements of a system. It shows the meaningful and useful concepts that exist in the real-world, software or hardware implementations, or in the abstract. It does not show...
The use of kernel functions is a common technique to extract important features from datasets. A quantum computer can be used to estimate kernel entries as transition amplitudes of unitary circuits. Quantum kernels exist that, subject to computational hardness assumptions, cannot be computed classically...
In particular, in conjunction with the solvation model based quantum chemistry computations at on density (SMD) continuum solva- tion model, were used to calculate geometries as a function of the CS–SCl dihedral angle. The variation in vibra- tionless energy as a function of the CS–SCl ...
