time delay between two photons by measuring their interference at a beam splitter through …

Single photons exhibit inherently quantum and unintuitive properties such as the Hong-Ou-
Mandel effect, demonstrating their bosonic and quantized nature, yet at the same time may …

We present a quantum sensing scheme achieving the ultimate quantum sensitivity in the
estimation of the transverse displacement between two photons interfering at a balanced …

Spectrally-resolved two-photon interference experimentally unveils a spectral-phase
footprint of a bandwidth-mismatched interaction between an ultrafast single photon and …

Recently, there have been several advancements in the development of sources for
narrowband non-classical light (with linewidth≲ MHz). This is motivated by applications in …
