Scalable entanglement distribution using encoded hybrid repeater chains
Stav Haldar, Saikat Guha, Don Towsley +1
Long-distance entanglement distribution requires error correction protocols to compensate for qubit decoherence in quantum memories and noise introduced during entanglement swappin…
High-Rate and Resource-Efficient All-Photonic Quantum Repeater Architectures with 9 km Repeater Spacing
Ryosuke Shiina, Kenneth Goodenough, Nathan Arnold +1
Quantum communication between two distant parties will serve as a cornerstone of the future quantum internet. However, generating enough entangled Bell pairs over long distances is…
Covert Entanglement Generation over Bosonic Channels
Evan J. D. Anderson, Michael S. Bullock, Ohad Kimelfeld +4
We explore covert entanglement generation over the lossy thermal-noise bosonic channel, which is a quantum-mechanical model of many practical settings, including optical, microwave…
Achievability of Covert Quantum Communication
Evan J. D. Anderson, Michael S. Bullock, Filip Rozpędek +1
We explore covert communication of qubits over an arbitrary quantum channel. Covert communication conceals the transmissions in the channel noise, ensuring that an adversary is una…
Role of Error Syndromes in Teleportation Scheduling
Aparimit Chandra, Filip Rozpędek, Don Towsley
Quantum teleportation enables quantum information transmission, but requires distribution of entangled resource states. Unfortunately, decoherence, caused by environmental interfer…
