Three-dimensional entanglement of orbital angular momentum states of an atomic qutrit and
a single photon qutrit has been observed. Their full state was reconstructed using quantum …

The propagation of transverse spatial correlations of photon pairs through arbitrary first-
order linear optical systems is studied experimentally and theoretically using the fractional …

We propose a method to generate a narrowband triphoton W state entangled in time (or
energy) via two four-wave mixing processes in cold atomic gas media. The calculation of …

Nonclassical multiphoton have attracted extensive attention to serve as entangled resources
for quantum information technology. Here, the continuous‐mode hyper‐entangled W‐class …

Triphotons have a more abundant energy structure compared to biphotons. Furthermore, as
the number of photons increases, excellent properties such as entangled multi-qubit states …

The generation of paired photons entangled in the spatial degree of freedom, ie, in orbital
angular momentum, offers a convenient physical resource to investigate the nature of …

The complex interactions between orbital angular momentum (OAM) of light and atoms are
particularly intriguing in the areas of quantum optics and quantum information. Building a …

In this work we present a series of results on four-wave mixing (FWM) processes induced by
structured light in atomic media. We start with a theoretical study focusing on a cascade …

Correlated light generated from atomic ensembles can have a central role in prominent
quantum information protocols, such as long-distance quantum communication. Here we …

In the same way that electronics is based on measuring and controlling the state of
electrons, the technological applications of quantum optics will be based on our abil ily to …
