Towards Distributed Quantum Computing: Quantum Gate Teleportation via Satellite-Distributed Entanglement under Atmospheric Depolarization

arXiv:2611.14623v1 Announce Type: new Abstract: We investigate quantum gate teleportation as a primitive for satellite-enabled distributed quantum computing. In the considered architecture, a satellite distributes entangled photon pairs to two optical ground stations, which transfer the shared quantum resource to remote quantum processing units. This entanglement is then used to implement a nonlocal controlled-NOT gate between two circuit qubits located in different processors. We formulate the minimal four-qubit protocol, consisting of two network qubits that provide the entangled resource and two circuit qubits on which the distributed gate is performed.
