Nearly 30 years ago, two-photon interference was observed, marking the beginning of a
new quantum era. Indeed, two-photon interference has no classical analogue, giving it a …

Interference, which refers to the phenomenon associated with the superposition of waves,
has played a crucial role in the advancement of physics and finds a wide range of …

As first demonstrated by Hanbury Brown and Twiss, it is possible to observe interference
between independent light sources by measuring correlations in their intensities rather than …

The emergence of quantum mechanics and general relativity has transformed our
understanding of the natural world significantly. However, integrating these two theories …

Previous demonstrations of free-space quantum communication in daylight have been
touted as significant for the development of global-scale quantum networks. Until now, no …

The Copenhagen interpretation, in which the core concepts are Heisenberg's uncertainty
principle and nonlocal EPR correlation, has been long discussed. Second-order …

Abstract Fluorescence Lifetime Imaging Microscopy in the time domain is typically performed
by recording the arrival time of photons either by using electronic time tagging or a gated …

Heralded single-photon source (HSPS) intrinsically suffers from the trade-off between the
heralded single-photon rate and the single-photon purity. To break through this trade-off …

Encoding information in the time–frequency domain demonstrates its potential for quantum
information processing. It offers a novel scheme for communications with large alphabets …
