Efficient Graph State Purification with Factorized Graph-Preserving Operations across Local Clifford Orbits
Mingyuan Wang, Guus Avis, Kenneth Goodenough +1
Graph states form a broad class of multipartite entangled states underlying measurement-based quantum computation, quantum networks, and stabilizer codes. However, systematic entan…
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…
Routing in Non-Isotonic Quantum Networks
Maxwell Tang, Garrett Hinkley, Kenneth Goodenough +2
Optimal routing in quantum-repeater networks requires finding the best path that connects a pair of end nodes. Most previous work on routing in quantum networks assumes utility fun…
Quantum Network Tomography for General Topology with SPAM Errors
Xuchuang Wang, Matheus Guedes De Andrade, Guus Avis +3
The goal of quantum network tomography (QNT) is the characterization of internal quantum channels in a quantum network from external peripheral operations. Prior research has prima…
GHZ-Preserving Gates and Optimized Distillation Circuits
Mingyuan Wang, Guus Avis, Stefan Krastanov
Greenberger-Horne-Zeilinger (GHZ) states play a central role in quantum computing and communication protocols, as a typical multipartite entanglement resource. This work introduces…
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…
