A Feasible Approach for Automatically Differentiable Unitary Coupled-Cluster on Quantum Computers
• aspuru-guzik-group/tequila
• 
We show that, within our framework, the gradient of an expectation value with respect to a parameterized n-fold fermionic excitation can be evaluated by four expectation values of similar form and size, whereas most standard approaches based on the direct application of the parameter-shift-rule come with an associated cost of O(2^(2n)) expectation values.

RGBeta: A Mathematica Package for the Evaluation of Renormalization Group $ β$-Functions
In completely generic four-dimensional gauge-Yukawa theories, the renormalization group $ \beta $-functions are known to the 3-2-2 loop order in gauge, Yukawa, and quartic couplings, respectively.

Crystal Graph Convolutional Neural Networks for an Accurate and Interpretable Prediction of Material Properties
Phys. Rev. Lett. 2017
• txie-93/cgcnn
• 
The use of machine learning methods for accelerating the design of crystalline materials usually requires manually constructed feature vectors or complex transformation of atom coordinates to input the crystal structure, which either constrains the model to certain crystal types or makes it difficult to provide chemical insights.

QUANTUM PHYSICS
Almost-linear time decoding algorithm for topological codes
Our algorithm has a worst case complexity of $O(n \alpha(n))$, where $n$ is the number of physical qubits and $\alpha$ is the inverse of Ackermann's function, which is very slowly growing.
