Coherent Three-Qubit Quantum Teleportation (Deferred Measurement) - references arXiv:2607.19770

This card demonstrates the quantum teleportation primitive - the textbook three-qubit protocol that transfers an unknown single-qubit state from a sender to a receiver using one shared entangled (Bell) pair plus, in the standard formulation, classical communication.

Because the Provenova gate set is unitary-only, we build the coherent variant via the principle of deferred measurement: the message qubit (q0) is prepared with a single Ry rotation, a Bell pair is created on (q1, q2), a Bell-basis rotation (CX then H) is applied to (q0, q1), and the usual Pauli corrections are realised as a deferred CX (from q1) and CZ (from q0) onto q2. The input amplitude on q0 is thereby mapped coherently onto the receiver qubit q2.

What the referenced paper reports: Abouamer, Sondergaard, and Popovski study encoded teleportation, in which the transmitted qubit is protected by a quantum error-correcting code and sent as a codeword. Their abstract frames reliability as a logical-error probability under latency constraints, where entanglement is accumulated over time and degrades in memory, and it examines how code length and code puncturing trade off against entanglement availability and fidelity across latency budgets, concluding that resource-aware adaptation matters for reliable quantum networking.

This Provenova card is inspired by that work only in so far as it isolates the underlying teleportation primitive. It is a deterministic simulator run on Provenova, not a reproduction of the paper's encoded-teleportation scheme, its punctured codes, its latency-reliability analysis, or any hardware result. No endorsement by the authors is implied; readers interested in the coding-theoretic and networking results should consult the linked arXiv abstract.
