We report on a universal method to measure the genuine indistinguishability of n photons— a crucial parameter that determines the accuracy of optical quantum computing. Our …
The geometrical arrangement of a set of quantum states can be completely characterized using relational information only. This information is encoded in the pairwise state overlaps …
We unveil the signature of many-body interference across dynamical regimes of the Bose- Hubbard model. Increasing the particles' indistinguishability enhances the temporal …
Multiphoton interference is at the heart of photonic quantum technologies. Arrays of integrated cavities can support bright sources of single photons with high purity and small …
Quantum networking relies on entanglement distribution between distant nodes, typically realized by swapping procedures. However, entanglement swapping is a demanding task in …
Boson bunching is among the most remarkable features of quantum physics. A celebrated example in optics is the Hong–Ou–Mandel effect, where the bunching of two photons arises …
Multiphoton contributions pose a significant challenge for the realisation of heralded single- photon sources (HSPS) based on nonlinear processes. In this work, we improve the quality …
We report on a multi-photon source based on active demultiplexing of single photons emitted from a resonantly excited GaAs quantum dot. Active temporal-to-spatial mode …
Entanglement and interference are both hallmark effects of quantum physics. Particularly rich dynamics arise when multiple (at least partially) indistinguishable particles are …
