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 cryptography is arguably the fastest growing area in quantum information science.
Novel theoretical protocols are designed on a regular basis, security proofs are constantly …

Bell's theorem proves that quantum theory is inconsistent with local physical models. It has
propelled research in the foundations of quantum theory and quantum information science …

In recent years, there has been a rising interest in high‐dimensional quantum states and
their impact on quantum communication. Indeed, the availability of an enlarged Hilbert …

Twisted photons can be used as alphabets to encode information beyond one bit per single
photon. This ability offers great potential for quantum information tasks, as well as for the …

Over the past few decades, significant progress has been made in quantum information
technology, from theoretical studies to experimental demonstrations. Revolutionary quantum …

The science of quantum information has arisen over the last two decades centered on the
manipulation of individual quanta of information, known as quantum bits or qubits. Quantum …

We review concepts and methods associated with quantum discord and related topics. We
also describe their possible connections with other aspects of quantum information and …

Quantum teleportation is one of the most important protocols in quantum information. By
exploiting the physical resource of entanglement, quantum teleportation serves as a key …

Applications of quantum technology often require fidelities to quantify performance. These
provide a fundamental yardstick for the comparison of two quantum states. While this is …
