Spyder: Teleportation-Based Quantum Routing in a Primordial Qubit Network with Synthetic Photons and Plasma Buffering

Abstract

This preprint introduces Spyder, a teleportation-based quantum routing framework that serves as the operational connectivity layer for the Matter–Light–Buffer Trinity. It integrates primordial-derived Atom GG qubits, synthetic photon channels via giant-atom lattices, and quantum-stable plasma buffers. The architecture leverages recent mobile spin qubit teleportation experiments and uses entropy-slope metrology of multi-qubit cat states for validation. This work builds directly on the authors’ prior Trinity series.

Quantum teleportation with dissimilar quantum dots over a hybrid quantum network

Alessandro Laneve, Giuseppe Ronco, Mattia Beccaceci +24 more

Photonic quantum information processing in metropolitan quantum networks lays the foundation for cloud quantum computing [1, 2], secure communication [3, 4], and the realization of a global quantum internet [5, 6]. This paradigm shift requires on-demand and high-rate generation of flying qubits and their quantum state teleportation over long distances [7]. Despite the last decade has witnessed an impressive progress in the performances of deterministic photon sources [8-11], the exploitation of distinct quantum emitters to implement all-photonic quantum teleportation among distant parties has remained elusive. Here, we overcome this challenge by using dissimilar quantum dots whose electronic and optical properties are engineered by light-matter interaction [12], multi-axial strain [13] and magnetic fields [14] so as to make them suitable for the teleportation of polarization qubits. This is demonstrated in a hybrid quantum network harnessing both fiber connections and 270 m free-space optical link connecting two buildings of the University campus in the center of Rome. The protocol exploits GPS-assisted synchronization, ultra-fast single photon detectors as well as stabilization systems that compensate for atmospheric turbulence. The achieved teleportation state fidelity reaches up to 82+-1%, above the classical limit by more than 10 standard deviations. Our field demonstration of all-photonic quantum teleportation opens a new route to implement solid-state based quantum relays and builds the foundation for practical quantum networks.

On-chip quantum teleportation

B. J. Metcalf, Nicholas L. Thomas-Peter, Justin B. Spring +10 more

Integrated quantum optics provides great promise for enabling photonic experiments to reach new regimes of complexity. Chip-based fabrication enables sophisticated networks involving multiple interfering pathways in a compact and stable physical architecture. In a recent work we demonstrated an advance in the complexity of these integrated devices by showing the first quantum interference of three separate input photons. Such complexity allows the demonstration of three qubit protocols never before realised on-chip. Here, we report the first results showing quantum teleportation on an integrated photonic circuit. Quantum teleportation provides the mechanism for quantum relay schemes and is an important constituent in linear optical quantum computing. Whilst demonstrations to date have relied upon complex and fragile bulk optical systems, being able to teleport quantum states on a compact and stable integrated architecture will be a critical step towards scalable realisations of these schemes.

Qubit teleportation between non-neighbouring nodes in a quantum network

Sophie Hermans, Matteo Pompili, Hans K. C. Beukers +3 more

Abstract Future quantum internet applications will derive their power from the ability to share quantum information across the network1,2. Quantum teleportation allows for the reliable transfer of quantum information between distant nodes, even in the presence of highly lossy network connections3. Although many experimental demonstrations have been performed on different quantum network platforms4–10, moving beyond directly connected nodes has, so far, been hindered by the demanding requirements on the pre-shared remote entanglement, joint qubit readout and coherence times. Here we realize quantum teleportation between remote, non-neighbouring nodes in a quantum network. The network uses three optically connected nodes based on solid-state spin qubits. The teleporter is prepared by establishing remote entanglement on the two links, followed by entanglement swapping on the middle node and storage in a memory qubit. We demonstrate that, once successful preparation of the teleporter is heralded, arbitrary qubit states can be teleported with fidelity above the classical bound, even with unit efficiency. These results are enabled by key innovations in the qubit readout procedure, active memory qubit protection during entanglement generation and tailored heralding that reduces remote entanglement infidelities. Our work demonstrates a prime building block for future quantum networks and opens the door to exploring teleportation-based multi-node protocols and applications2,11–13.

Proposed Topological Protection Mechanisms Using OAM Modes in Dusty Plasmas for Hybrid Quantum Systems

Denise Venerable, Grok xAI, Gemini Google DeepMind

This preprint proposes a topological protection mechanism for hybrid quantum systems using orbital angular momentum (OAM) eigenmodes in unmagnetized dusty plasmas. Building directly on the Spyder v2 teleportation routing architecture and the Matter–Light–Buffer Trinity, we introduce an active plasma-buffered “Lock and Key” layer that selectively couples signals with matching topological charge while suppressing phonon-induced noise and mismatched modes. Key Contributions Theoretical foundation grounded in Chen et al. (2017) OAM eigenmodes in plasmas. Extension of the Spyder Buffer Layer with topological filtering. Hybrid QNN feedback controller for real-time phase matching and entropy monitoring. Concrete four-stage experimental protocol and entropy-slope metrology. Proposed table-top validation using standard GEC Reference Cell setups. This work provides a practical near-term pathway to improve decoherence resilience in hybrid quantum networks and serves as a stepping stone toward more scalable architectures.
