Entanglement Distribution and Teleportation in Assisted and Scalable Quantum Access Networks

August 11, 2026Amir Mohammad Yaghoobianzadeh, Jawad A. SalehiEarly Access, Open AccessDetectors, Joining processes, Matrices, Modeling, Passive optical networks, Probability, Protocols, Reviews, Teleportation, Textile fibers

Abstract: We have investigated the entanglement distribution and quantum teleportation in quantum passive optical networks (QPONs), where an entangled state is distributed between the central node and multiple end users through lossy fibers and passive optical splitter/combiner. The entanglement degradation is quantified using logarithmic negativity, and teleportation fidelity both in non-assisted and assisted strategies. We […]

Perfect Quantum Teleportation in Memory Amplitude-Damping Channels Based on Pre-flipping and Environment-Assisted Measurement

May 19, 2026Shiye Zhang, Sajede Harraz, Sen Kuang, Shuang CongEarly Access, Open AccessDamping, Electro-absorption modulators, Measurement, Memory, Noise, Probability, Protocols, Quantum communication, Qubit, Teleportation

Abstract: Most existing quantum teleportation schemes do not consider the memory effect of noise, which is becoming increasingly serious in practical quantum communication. In this paper, we propose two quantum teleportation protocols for noisy memory channels: one based on pre-flipping (PF) and another incorporating pre-flipping with environment-assisted measurement (PF-EAM). In the PF protocol, a pre-flipping […]

Abstract: Traditional many-body teleportation relies on the strong interaction property of a quantum many-body system, which usually requires numerous qubits and entanglement resources, making it difficult to realize experimentally. A natural scheme is to use a 1-D spin chain with simple structure to realize many-body teleportation. In this article, we analyze the conditions for general […]

Advance Sharing Procedures for the Ramp Quantum Secret Sharing Schemes With the Highest Coding Rate

Abstract: In some quantum secret sharing schemes, it is known that some shares can be distributed to participants before a secret is given to the dealer. However, it is unclear whether some shares can be distributed before a secret is given in the ramp quantum secret sharing schemes with the highest coding rate. This article […]

Reliable Quantum Communications Based on Asymmetry in Distillation and Coding

May 10, 2024Lorenzo Valentini, René Bødker Christensen, Petar Popovski, Marco ChianiQuantum InternetEncoding, Protocols, Quantum computing, Quantum entanglement, Qubit, Reliability, Teleportation

The reliable provision of entangled qubits is an essential precondition in a variety of schemes for distributed quantum computing. This is challenged by multiple nuisances, such as errors during the transmission over quantum links, but also due to degradation of the entanglement over time due to decoherence. The latter can be seen as a constraint […]

Optimal Partitioning of Quantum Circuits Using Gate Cuts and Wire Cuts

December 26, 2023Sebastian Brandhofer, Ilia Polian, Kevin KrsulichQuantum SoftwareLogic gates, Quantum circuit, Quantum computing, Qubit, Runtime, Teleportation, Wires

A limited number of qubits, high error rates, and limited qubit connectivity are major challenges for effective near-term quantum computations. Quantum circuit partitioning divides a quantum computation into classical postprocessing steps and a set of smaller scale quantum computations that individually require fewer qubits, lower qubit connectivity, and typically incur less error. However, as partitioning […]

DQRA: Deep Quantum Routing Agent for Entanglement Routing in Quantum Networks

November 2, 2022Linh LeOpen Access, Quantum InternetNeural networks, Quantum entanglement, Quantum networks, Qubit, Repeaters, Routing, Teleportation

Quantum routing plays a key role in the development of the next-generation network system. In particular, an entangled routing path can be constructed with the help of quantum entanglement and swapping among particles (e.g., photons) associated with nodes in the network. From another side of computing, machine learning has achieved numerous breakthrough successes in various […]

Efficient Quantum Network Communication Using Optimized Entanglement Swapping Trees

November 2, 2022Mohammad GhaderibanehOpen Access, Quantum InternetDegradation, Photonics, Quantum entanglement, Quantum networks, Quantum state, Qubit, Teleportation

Quantum network communication is challenging, as the no-cloning theorem in the quantum regime makes many classical techniques inapplicable; in particular, the direct transmission of qubit states over long distances is infeasible due to unrecoverable errors. For the long-distance communication of unknown quantum states, the only viable communication approach (assuming local operations and classical communications) is […]

A Connection-Oriented Entanglement Distribution Design in Quantum Networks

November 2, 2022Jian LiOpen Access, Quantum InternetProtocols, Quality of service, Quantum entanglement, Quantum networks, Qubit, Routing, Teleportation

Quantum networks create a completely new way for communication, and the most important function of a quantum network is to generate long-distance quantum entanglement to serve a number of quantum applications. As the scale of the network expands, in order to establish end-to-end entanglement between two remote nodes, entangled pairs need to be generated and […]
