Distributing circuits over heterogeneous, modular quantum computing network architectures

Pablo Andres-Martinez, Tim Forrer, Daniel Mills +5

We consider a heterogeneous network of quantum computing modules, sparsely connected via Bell states. Operations across these connections constitute a computational bottleneck and…

Entanglement-efficient bipartite-distributed quantum computing

Jun-Yi Wu, Kosuke Matsui, Tim Forrer +5

In noisy intermediate-scale quantum computing, the limited scalability of a single quantum processing unit (QPU) can be extended through distributed quantum computing (DQC), in whi…

Quantum correlations on the no-signaling boundary: self-testing and more

Kai-Siang Chen, Gelo Noel M. Tabia, Chellasamy Jebarathinam +3

In device-independent quantum information, correlations between local measurement outcomes observed by spatially separated parties in a Bell test play a fundamental role. Even thou…

Generation and evaluation of multipartite entanglement with multi-rail encoding in linear optics networks

Jun-Yi Wu

A linear optics network is a multimode interferometer system, where indistinguishable photon inputs can create nonclassical interference that can not be simulated with classical co…

Derivation of the statistics of quantum measurements from the action of unitary dynamics

Keito Hibino, Kazuya Fujiwara, Jun-Yi Wu +2

Quantum statistics is defined by Hilbert space products between the eigenstates associated with state preparation and measurement. The same Hilbert space products also describe the…

Evaluation of bipartite entanglement between two optical multi-mode systems using mode translation symmetry

Jun-Yi Wu, Holger F. Hofmann

Optical multi-mode systems provide large scale Hilbert spaces that can be accessed and controlled using single photon sources, linear optics and photon detection. Here, we consider…

Quantum effects in the interference of photon number states

Holger F. Hofmann, Keito Hibino, Kazuya Fujiwara +1

Multi-photon interference results in modulations of output probabilities with phase shift periods that are much shorter than 2 Pi. Here, we investigate the physics behind these sta…

Determining X-chains in graph states

Jun-Yi Wu, Hermann Kampermann, Dagmar Bruß

The representation of graph states in the X-basis as well as the calculation of graph state overlaps can efficiently be performed by using the concept of X-Chains [Phys. Rev. A 92(…

Group structures and representations of graph states

Jun-Yi Wu, Hermann Kampermann, Dagmar Bruß

A special configuration of graph state stabilizers, which contains only Pauli operators, is studied. The vertex sets associated with such configurations are defined as wh…

Randomized Graph States and their Entanglement Properties

Jun-Yi Wu, Matteo Rossi, Hermann Kampermann +4

We introduce a class of mixed multiqubit states, that corresponds to a randomized version of graph states. Such states arise when a graph state is prepared with noisy or imperfect…

Determining lower bounds on a measure of multipartite entanglement from few local observables

Jun-Yi Wu, Hermann Kampermann, Dagmar Bruß +2

We introduce a method to lower bound an entropy-based measure of genuine multipartite entanglement via nonlinear entanglement witnesses. We show that some of these bounds are tight…
