For friends of #QuantumControl and #QuantumTechnologies: Out now in #PRXQuantum, our newest paper.
How do you combine feedback and gradient-based optimization of control strategies --- something that is very useful for optimizing quantum error correction and many other important tasks? "feedback GRAPE" is our answer, as a new technique:

A wavefront shaping approach enables protection of high-dimensional #entangled photons traversing a scattering medium, a situation that typically hinders the building of practical quantum microscopy and #QuantumKeyDistribution. -

The fidelity of the QAOA algorithm is found to obey a scaling law associated with the bond dimension of matrix product states, benchmarking the performance of quantum hardware in realistic setups. #rigetti -
