Manipulation of quantum optical pulses, such as single photons or entangled photon pairs,
enables numerous applications, from quantum communications and networking to …

High-dimensional quantum entanglement is currently one of the most prolific fields in
quantum information processing due to its high information capacity and error resilience. A …

Strongly driven nonlinear optical processes such as spontaneous parametric down-
conversion and spontaneous four-wave mixing can produce multiphoton nonclassical …

We demonstrate the ultimate sensitivity allowed by quantum physics in the estimation of the
time delay between two photons by measuring their interference at a beam splitter through …

Traditional Hong-Ou-Mandel (HOM) interferometry, insensitive to photons phase mismatch,
proved to be a rugged single-photon interferometric technique. By introducing a post-beam …

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 …

Franson interference can be used to test the nonlocal features of energy-time entanglement
and has become a standard in quantum physics. However, most of the previous Franson …

We propose theoretically a quantum interferometer in which the NOON state interferometer
is combined with the Hong-Ou-Mandel interferometer. With this interferometer, the temporal …

Entangled qudits, the high-dimensional entangled states, play an important role in the study
of quantum information. How to prepare entangled qudits in an efficient and easy-to-operate …

Multiphoton interference is an essential phenomenon at the very heart not only of
fundamental quantum optics and applications in quantum information processing and …
