Sequential vs. Synchronized Entanglement Swapping: QKD Secret-Key Rate under Optimized Link-Layer Control
Priyam Srivastava, Akshat R. Sabavat, Siddharth Jain +6
Quantum repeater chains build long-distance entanglement for quantum key distribution (QKD) by creating pairs on short links and joining them through entanglement swapping. Because…
Decentralized Consensus from Quantum Proof of Position
Dar Gilboa, Siddhartha Jain, Or Sattath
We construct an energy efficient consensus protocol with geospatial position as an external resource by using quantum computers. Economic resources of some form are essential in de…
Anonymous Quantum Tokens with Classical Verification
Dmytro Gavinsky, Dar Gilboa, Siddhartha Jain +2
The no-cloning theorem can be used as a basis for quantum money constructions which guarantee unconditionally unforgeable currency. Existing schemes, however, either (i) require lo…
Consumable Data via Quantum Communication
Dar Gilboa, Siddhartha Jain, Jarrod R. McClean
Classical data can be copied and re-used for computation, with adverse consequences economically and in terms of data privacy. Motivated by this, we formulate problems in one-way c…
