Faster Quantum Chemistry Simulation on Fault-Tolerant Quantum Computers
N. Cody Jones,James D. Whitfield,James D. Whitfield,Peter L. McMahon,Man-Hong Yung,Rodney Van Meter,Alán Aspuru-Guzik,Yoshihisa Yamamoto,Yoshihisa Yamamoto +8 more
TL;DR: This work proposes methods which substantially improve the performance of a particular form of simulation, ab initio quantum chemistry, on fault-tolerant quantum computers; these methods generalize readily to other quantum simulation problems.
Understanding Polymorphism in Organic Semiconductor Thin Films through Nanoconfinement
Ying Diao,Kristina M. Lenn,Wen-Ya Lee,Martin A. Blood-Forsythe,Jie Xu,Yisha Mao,Yeongin Kim,Julia Reinspach,Steve Park,Alán Aspuru-Guzik,Gi Xue,Paulette Clancy,Zhenan Bao,Stefan C. B. Mannsfeld +13 more
TL;DR: It is demonstrated that the nanoconfinement effect combined with the flow-enhanced crystal engineering technique is a powerful and likely material-agnostic method to identify existing polymorphs in OSC materials and to prepare the individual pure forms in thin films at ambient conditions.

The theory of variational hybrid quantum-classical algorithms
TL;DR: This work develops a variational adiabatic ansatz and explores unitary coupled cluster where it is shown how the use of modern derivative free optimization techniques can offer dramatic computational savings of up to three orders of magnitude over previously used optimization techniques.

Quantum Simulation of Helium Hydride Cation in a Solid-State Spin Register.
Ya Wang,Florian Dolde,Jacob Biamonte,Ryan Babbush,Ryan Babbush,Ville Bergholm,Sen Yang,Ingmar Jakobi,Philipp Neumann,Alán Aspuru-Guzik,James D. Whitfield,Jörg Wrachtrup +11 more
TL;DR: This work uses a solid-state quantum register realized in a nitrogen-vacancy defect in diamond to compute the bond dissociation curve of the minimal basis helium hydride cation, HeH(+), with an energy uncertainty of 10(-14) hartree, which is 10 orders of magnitude below the desired chemical precision.

Quantum Neuron: an elementary building block for machine learning on quantum computers
TL;DR: A small quantum circuit is proposed that naturally simulates neurons with threshold activation and defines a building block, the "quantum neuron", that can reproduce a variety of classical neural network constructions while maintaining the ability to process superpositions of inputs and preserve quantum coherence and entanglement.
