Thirty years after it was first proposed, quantum teleportation remains one of the most
important protocols in quantum information and quantum technologies, enabling the …

Quantum secret sharing (QSS) has emerged as a promising avenue for storing secret with
quantum-enhanced security. However, practical applications are hindered by the challenge …

Quantum secure direct communication (QSDC) can transmit secret messages without keys,
making it an important branch of quantum communication. We present a hybrid …

Abstract Entanglement and Einstein–Podolsky–Rosen (EPR) steering are nonlocal quantum
correlations, which are relevant resources for quantum information protocols. EPR steering …

Quantum teleportation exemplifies how the transmission of quantum information starkly
differs from that of classical information and serves as a key protocol for quantum …

Quantum nonlocality as a witness of entanglement plays a crucial role in various fields.
Existing quantum monogamy relations rule out the possibility of simultaneous violations of …

In this paper, we concern on different methods to realize hierarchical quantum information
splitting of an arbitrary m-qudit state with multiple agents. Two deterministic universal …

Here, we propose to generate the nonreciprocal macroscopic entanglement and steering of
magnon modes from three yttrium iron garnet spheres, which are placed in a spinning …

Hyperentanglement, defined as the simultaneous entanglement in several independent
degrees of freedom (DOFs) of a quantum system, is a fascinating resource in quantum …

The emerging field of quantum computing has shown it might change how we process
information by using the unique principles of quantum mechanics. As researchers continue …
