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 […]

Clifford Manipulations of Stabilizer States – Application to Linear Optical Qubits

August 6, 2026Ashlesha Patil, Saikat GuhaEarly Access, Open AccessCircuits, Detectors, Encoding, Hilbert space, Measurement, Polarization, Probability, Quantum circuit, Qubit, Rails

Abstract: The single-photon dual-rail qubit is popular for photonic quantum computing and communications, both due to gates being realizable with linear optics (LO) and photon detection, as well as easy interfaces with matter quantum memories. Two-qubit operations, i.e., two-qubit gates followed by the measurement of one (Type-I fusion) or both (Type-II fusion) qubits, are, however, […]

Quantum Repeater Chains via Cavity-Magnon for Scalable Quantum Networks

Abstract: Scalable quantum networks require quantum repeaters to overcome major challenges such as photon loss and decoherence in long-distance quantum communication. In this paper, we present a cavity-magnon quantum repeater architecture that exploits the frequency tunability and hybrid integration capabilities of magnonic platforms to enable efficient entanglement swapping across multi-hop networks. The coherence budget is […]

Quantum-Based Resilient Routing in Networks: Minimizing Latency Under Dual-Link Failures

June 11, 2026Maher Harb, Nader Foroughi, Matt Stehman, Bob Lutz, Nati Erez, Erik GarcellEarly Access, Open AccessAlgorithms, Costing, Costs, Hardware, Joining processes, Modeling, Optimization, Probability, Qubit, Timing

Abstract: Network optimization problems represent large combinatorial search spaces that grow exponentially with network size, making them computationally intensive to solve. This paper addresses the latency-resilient Layer 3 routing optimization problem in telecommunications networks with predefined Layer 1 optical links. We formulate this problem as a graph-based optimization problem with the objective of minimizing latency, […]

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 […]

Quantum Circuit-Based Adaptation for Credit Risk Analysis

Abstract: Noisy and Intermediate-Scale Quantum, or NISQ, processors are sensitive to noise, prone to quantum decoherence, and are not yet capable of continuous quantum error correction for fault-tolerant quantum computation. Hence, quantum algorithms designed in the pre-fault-tolerant era cannot neglect the noisy nature of the hardware, and investigating the relationship between quantum hardware performance and […]
