TL;DR: In this article, the authors present a general technique that harnesses multi-level information carriers to reduce the number of gates required to build quantum logic gate sets, enabling the construction of key quantum circuits with existing technology.

TL;DR: This work generalizes Kitaev’s phase estimation algorithm using adaptive measurement theory to achieve a standard deviation scaling at the Heisenberg limit, representing a drastic reduction in the complexity of achieving quantum-enhanced measurement precision.

TL;DR: This work demonstrates complete characterization of a two-qubit entangling process--a linear optics controlled-NOT gate operating with coincident detection--by quantum process tomography by using a maximum-likelihood estimation to convert the experimental data into a physical process matrix.

TL;DR: In this article, it was shown that entanglement is necessary for steering, but steering can be achieved, as has now been demonstrated experimentally, with states that cannot violate a Bell inequality and therefore non-locality.

TL;DR: The photonic quantum computing represents an exciting path to medium and large-scale processing as mentioned in this paper, and the development of integrated platforms, improved sources and detectors, novel noise-tolerant theoretical approaches, and more have solidified it as a leading contender for both quantum information processing and quantum networking.
