Entanglement Goes Classically High-Dimensional

Complex forms of quantum entanglement can arise in two qualitatively diferent ways: either between many qu-bits or between two particles with higher- than- qubit dimension. While both the many- qubit frontier and the high- dimension frontier are well established, state- of- the- art quantum technology is becoming increasingly able to create and manipulate entangled “Entanglement goes classically high-dimensional”出自《光：科学与应用(英文版)》期刊2021年第5期文献，主题关键词涉及有等。钛学术提供该文献下载服务。

High-dimensional quantum entanglement is generated via a singly filtered biphoton frequency comb, with energy-time entanglement witnessed for both between time bins and frequency bins. Despite these impressive advances, the prevailing para-digm is limited in two-DoF (bipartite) and two-dimensional (2D) classically entangled states of light, the classical ana-logy to two-photon

High-dimensional classically entangled light from a laser

Here, we report a classically high-dimensional correlation, which is mathematically equivalent to its quantum counterparts and can be used to simulate the violations of the high-dimensional Bell inequalities.

Cluster states with three-dimensional connectivities are realized by selecting specific time–frequency mode bases for multimode quantum light. The cluster state generation is verified by Different physical concepts underlie the creation of high-dimensionally entangled photon pairs. Conservation laws result in correlations that if coherent in turn yield high-dimensionally entangled photon pairs. Multiple indistinguishable and coherent possibilities can be combined such that custom-tailored, high-dimensional entanglement is created.

The efficient generation of high-fidelity entangled states is the key element for long-distance quantum communication, quantum computation, and other quantum technologies, and at laws result in correlations the same time the most resource-consuming part in many schemes. We present a class of entanglement-assisted entanglement purification protocols that can generate high-fidelity

Increasing attention in recent years has been drawn to high-dimensional entanglement involving much larger dimensionality in a single degree of freedom (DoF).

This paper explores advancements in high-dimensional quantum entanglement, focusing on its applications and challenges in quantum information processing and communication. Here, we propose a method to realize high-dimensional quantum holography by using high-dimensional orbital angular momentum (OAM) entanglement. A high-capacity OAM-encoded quantum 1 Qiwen holographic system can be obtained by multiplexing a wide range of OAM-dependent holographic images. We demonstrate a multidimensional integrated quantum photonic platform able to generate, control, and analyze high-dimensional entanglement. A programmable bipartite entangled system is realized with dimensions up to 15 × 15 on a large

Nonclassical states of light constitute crucial resources for quantum information technologies due to their ability to transmit easily, resist decoherence, and offer various ways to encode information [1]. Recently, considerable attention has been devoted to entanglement in high-dimensional degrees of freedom of photons [2] to push fundamental tests of quantum mechanics [3, 4], Furthermore, using signal waves with different topological charges and beam radii to generate spatially resolved metasurfaces, we realize single-photon sources of high-dimensional spin-orbital quantum emission and experimentally demonstrate the entanglement of high-dimensional superposition states with high fidelity.

Despite these impressive advances, the prevailing para-digm is limited in two-DoF (bipartite) and two-dimensional (2D) classically entangled states of light, the classical ana-logy to two-photon qubit entanglement, which has proved useful in describing such beams as states on a sphere40,41. The ability to access more DoFs and arbitrarily engineered high-dimensional High-dimensional entangled states are promising candidates for increasing the security and encoding capacity of quantum systems. While it is possible to witness and set bounds for the entanglement

In this chapter we outline the basic concepts of classical entanglement, providing a theoretical framework that transcends optical fields. Then, using structured light fields in polarization and spatial mode as our example, we illustrate how to create, detect, and exploit such classically entangled light.

The demonstration builds on existing properties and

Entanglement is an important resource for quantum technologies. There are many ways quantum systems can be entangled, ranging from the two-qubit case to entanglement in high dimensions or between Since its discovery in the last century, quantum entanglement has challenged some of our most cherished classical views, such as locality and reality. Today, the second quantum revolution is in full swing and promises to revolutionize areas such as computation, communication, metrology, and imaging. Here, we review conceptual and experimental Laser beams from a customarily designed resonator can produce vectorial structured light fields as classical analogs to high-dimensional multipartite quantum entangled states.
