2015 · Physical Review A

We experimentally construct a three-qubit entangled $W$ superposition $(W\overline{W})$ state on an NMR quantum information processor. We give a measurement-based filtration protocol for the invertible local operation (ILO) that converts the $W\overline{W}$ state to the …

Neural network assisted quantum state and process tomography using limited data sets

2023 · arXiv (Cornell University)

In this study we employ a feed-forward artificial neural network (FFNN) architecture to perform tomography of quantum states and processes obtained from noisy experimental data. To evaluate the performance of the FFNN, we use a …
