Suppressing errors is the central challenge for useful quantum computing, requiring
quantum error correction (QEC),,,–for large-scale processing. However, the overhead in the …

Graphs have provided an expressive mathematical tool to model quantum-mechanical
devices and systems. In particular, it has been recently discovered that graph theory can be …

Metasurfaces have been continuously garnering attention in both scientific and industrial
fields, owing to their unprecedented wavefront manipulation capabilities using arranged …

Quantum photonic technologies such as quantum communication, sensing or computation
require efficient, stable and pure single-photon sources. Epitaxial quantum dots (QDs) have …

Quantum random sampling is the leading proposal for demonstrating a computational
advantage of quantum computers over classical computers. Recently the first large-scale …

We report new Gaussian boson sampling experiments with pseudo-photon-number-
resolving detection, which register up to 255 photon-click events. We consider partial photon …

The generation, manipulation, storage, and detection of single photons play a central role in
emerging photonic quantum information technology. Individual photons serve as flying …

In this short review article, we aim to provide physicists not working within the quantum
computing community a hopefully easy-to-read introduction to the state of the art in the field …
