Co-transmission of classical data and continuous-variable entanglement over a single quantum channel
Nicholas Zaunders, Timothy C. Ralph
Displacement-based simultaneous quantum-classical communications (SQCC) protocols, as originally proposed, are generally incompatible with the majority of useful quantum communicat…
Generalised simultaneous transmission of arbitrary quantum states and classical information
Nicholas Zaunders, Timothy C. Ralph
We present a protocol which allows for arbitrary optical quantum states to simultaneously carry and transmit classical data, without sacrificing the integrity of either the quantum…
Entanglement distribution via satellite: an evaluation of competing protocols assuming realistic free-space optical channels
Nicholas Zaunders, Timothy C. Ralph
A key technical requirement of any future quantum network is the ability to distribute quantum-entangled resources between two spatially separated points at a high rate and high fi…
Enhanced Simultaneous Quantum-Classical Communications Under Composable Security
Nicholas Zaunders, Ziqing Wang, Robert Malaney +2
Simultaneous quantum-classical communications (SQCC) protocols are a family of continuous-variable quantum key distribution (CV-QKD) protocols which allow for quantum and classical…
