Quantum Advantage for Coordinated Frequency Selection Against Distributed Jammers
Stephanie Wehner
Consider two parties who want to agree on a common frequency band for communication in the presence of independent jammers. Such jammers block a different subset of bands at each s…
Remotely Preparing Many Qubits with a Single Photon
Tzula B. Propp, Benedikt Tissot, Anders S. Sørensen +1
A single photon in a superposition of modes naturally encode a -dimensional quantum system, a so-called qudit. We show that such superpositions can be leveraged to achieve a…
Probabilistic Cutoffs in Homogeneous Quantum Repeater Chains
Jeroen Grimbergen, Stav Haldar, Alvaro Gomez Inesta +1
We study quantum repeater chains in which entangled links between neighbouring nodes are created through heralded entanglement generation and adjacent links are swapped as soon as…
Requirements for Teleportation in an Intercity Quantum Network
Soubhadra Maiti, Guus Avis, Sounak Kar +1
We investigate the hardware requirements for quantum teleportation in an intercity-scale network topology consisting of two metropolitan-scale networks connected via a long-distanc…
Quantum Strategies to Overcome Classical Multiplexing Limits
Tzula B. Propp, Jeroen Grimbergen, Emil R. Hellebek +5
Near-term quantum networks face a bottleneck due to low quantum communication rates. This degrades performance both by lowering operating speeds and increasing qubit storage time i…
On the accuracy of twirled approximations in repeater chains
Bethany Davies, Guus Avis, Stephanie Wehner
In the performance analysis of quantum networks, it is common to approximate bipartite entangled states as either being Bell-diagonal or Werner states. We refer to these as twirled…
