communication and computation. However, the entanglement is fragile due to the presence …

Structured light refers to the arbitrarily tailoring of optical fields in all their degrees of freedom
(DoFs), from spatial to temporal. Although orbital angular momentum (OAM) is perhaps the …

Distributed secure quantum machine learning (DSQML) enables a classical client with little
quantum technology to delegate a remote quantum machine learning to the quantum server …

The radiation of electromagnetic and mechanical waves depends not only on the intrinsic
properties of the emitter but also on the surrounding environment. This principle has laid the …

With the development of quantum technologies, the quantum internet has demonstrated
unique applications beyond the classical internet and has been investigated extensively in …

Holography is a cornerstone characterization and imaging technique that can be applied to
the full electromagnetic spectrum, from X-rays to radio waves or even particles such as …

We propose a three-party quantum secure direct communication (QSDC) protocol with
hyperentanglement in both spatial-mode and polarization degrees of freedom. The secret …

Hyperentanglement, the simultaneous entanglement in more than one degree of freedom
(DOF), plays an important role in quantum communication and quantum information …

The hope for a futuristic global quantum internet that provides robust and high-capacity
quantum information transfer lies largely on qudits, the fundamental quantum information …

This study proposes the first high-capacity quantum secure direct communication (QSDC)
with two-photon six-qubit hyper-entangled Bell states in two longitudinal momentum and …
