“…Superdense encoding, leveraging the Bell states, has several applications in quantum secure communication and quantum cryptography [113]- [115]. In a quantum communication protocol, utilizing pre-shared quantum entanglement enhances the data transmission rate via a quantum channel, enabling the transmission of two classical bits using two entangled qubits, as opposed to classical transmissions [116], [117]. In other words, superdense encoding increases the maximum information rate to two bits per qubit, compared to one bit in classical communications, provided that Alice and Bob have access to entangled qubits.…”

The existing body of research on quantum embedding techniques is not only confined in scope but also lacks a comprehensive understanding of the intricacies of the quantum embedding process. To address this critical issue, this article explores quantum encoding schemes, uncovering valuable insights into their encoding algorithms from theoretical foundations to a mathematical perspective, as well as practical applications. Initially, the article briefly overviews classical computing and the limitations associated with classical bits in representing and processing complex information. Next, the article scrutinizes a variety of quantum embedding patterns, including basis encoding, amplitude encoding, Qsample encoding, angle encoding, quantum associative memory encoding, quantum random access memory, superdense encoding, Hamiltonian encoding, and others. In addition, each technique is accompanied by mathematical formulas and examples illustrating how each strategy can be applied. Finally, the article provides a comparative analysis of different quantum embedding/encoding methods, outlining their strengths and limitations. Overall, this insightful article highlights the potential of quantum encoding techniques for efficient information processing beyond classical bits, thereby facilitating scientists and design engineers in selecting the most appropriate encoding technique to develop smart algorithms for revolutionizing the field of quantum computing.INDEX TERMS Encoding patterns, qubits, quantum computing, quantum information processing, quantum circuits.

“…In similar entangled states between multiple particles, entanglement swapping can also be achieved in intraparticle entangled states, causing two previously unrelated quantities to entangle. Intraparticle entanglement swapping can be applied in super quantum dense encoding [14], quantum information transmission [15][16][17][18], and quantum teleportation [19,20]. This work first analogizes the distinctions and connections between two kinds of entangled states.…”

Entanglement is one of the most striking features in quantum systems. Today, quantum entanglement plays a vital role in quantum technology, the non-classical correlation of quantum entanglement is an important resource for quantum communication and quantum computing. Entanglement can be divided into two categories: between multi-particle systems and between various degrees of freedom in a single-particle system (intraparticle entangled states). This work first analogized the distinctions and connections between two kinds of entangled states. Then it designed three types of entanglement-swapping methods based on Bell state joint measurement, cross-Kerr medium, and linear optical elements for intraparticle entangled states by analogizing the entanglement swapping between multiple particles. Intraparticle entanglement swapping can be applied in super quantum dense encoding, quantum information transmission, and quantum teleportation. This work is beneficial for promoting the development of quantum information technologies.

“…Unlike classical communication, which relies on computational complexity to ensure security, confidentiality in quantum information transmission is guaranteed using the fundamental characteristics and principles of quantum physics. With the in-depth research of many scholars, quantum communication has made significant progress in theory and experiment, and many quantum communication protocols have been proposed, such as quantum key distribution [1][2][3][4], remote state preparation [5][6][7][8], quantum direct communication and super dense coding [9][10][11][12][13], quantum network [14][15][16]. Bennett et al pioneered the quantum teleportation protocol in 1993 [17], from then on, scholars have proposed a lot of schemes for the teleportation of arbitrary single-qubit states, two-qubit states, and different forms of W states, GHZ states, cluster states, other quantum states theoretically and experimentally by using various entangled quantum channels [18][19][20][21].…”

This article proposes an asymmetric bidirectional hierarchical quantum teleportation protocol, which is based on a quantum channel composed of a maximum of eight-qubit entangled state. With this method, Alice can transmit an unknown single-qubit state to Bob, meanwhile, Bob can transmit an arbitrary unknown two-qubit quantum state to Alice. As a sender with high authority, Bob can send any unknown two-qubit quantum state to Alice only under the sole control of the controller Charlie; Alice, as a sender with low-level permissions, if Bob intends to receive the unknown single-qubit quantum state sent by Alice, he must get the permission and assistance of Charlie and David to complete the communication.
