Hermans, S.L.N. (author), Pompili, M. (author), Dos Santos Martins, L. (author), RodriguezPardo Montblanch, A. (author), Beukers, H.K.C. (author), Baier, S. (author), Borregaard, J. (author), Hanson, R. (author)The generation of entanglement between remote matter qubits has developed into a key capability for fundamental investigations as well as for emerging quantum technologies. In the singlephoton, protocol entanglement is heralded by generation of qubitphoton entangled states and subsequent detection of a single photon behind a beam splitter....journal article 2023

de Kluijver, Lisa (author)Throughout the work, the goal was to develop the physical layer of a quantum network stack. The layer of the network stack connected to the physical layer is the link layer. For entanglementbased quantum networks, we demonstrated the successful operation of a link layer and a physical layer. The physical layer’s entanglement generation...master thesis 2022

Abrahams, Joël (author)Quantum networks allow multiple devices to exchange information encoded within quantum systems.<br/>Such quantum networks use classical control messages to coordinate entanglement between nodes.<br/>Third parties which can forge such control messages may interfere with the workings of quantum links, however:<br/>They may either perform...master thesis 2022

Goodenough, K.D. (author)The research presented in this thesis focused on the problem of entanglement distribution. Simply put, the two main problems facing (practical) implementation of entanglement distribution over quantum networks are loss and noise. Quantum repeaters are meant to overcome the effects of loss, but in practice their implementation always comes at the...doctoral thesis 2022

Dahlberg, E.A. (author), van der Vecht, B. (author), Delle Donne, C. (author), Skrzypczyk, M.D. (author), te Raa, I. (author), Kozlowski, W. (author), Wehner, S.D.C. (author)We introduce NetQASM, a lowlevel instruction set architecture for quantum internet applications. NetQASM is a universal, platformindependent and extendable instruction set with support for local quantum gates, powerful classical logic and quantum networking operations for remote entanglement generation. Furthermore, NetQASM allows for close...journal article 2022

Jirovská, Hana (author)There has been a lot of research focused on the next generation of the internet, the socalled quantum networks. This analysis has been so far limited to mostly symmetrical architectures, but any nearterm realisations of quantum networks using existing fibre topologies will contain asymmetry. In this thesis, we investigate how midpoint...bachelor thesis 2021

ASHOK KUMAR VATTEKKAT, RAVISANKAR (author)Quantum software development is the process of conceiving, specifying, designing, programming, documenting, and testing executable quantum programs that are meant to run on practical quantum hardware. Even though quantum software development research has gained traction over the years, it is still mainly focused on problem analysis, language...master thesis 2021

Gauthier, Scarlett (author)Preparation of multipartite entangled quantum states under realistic experimental conditions invariably results in states with nonunit fidelity to the target state. Purification protocols address the need for higher fidelity states than what can be directly prepared. These protocols consume several noisy input states and return an output state...master thesis 2021

Dahlberg, E.A. (author)Quantum mechanics shows that if one is able to generate and manipulate entanglement over a distance, one is able to perform certain tasks which are impossible using only classical communication. Classical communication refers to what is used in the Internet of today. A quantum internet would therefore bring new capabilities to our highly...doctoral thesis 2021

Horta Ferreira da Silva, F. (author), TorresKnoop, Ariana (author), Coopmans, T.J. (author), Maier, D.J. (author), Wehner, S.D.C. (author)Longdistance quantum communication via entanglement distribution is of great importance for the quantum internet. However, scaling up to such long distances has proved challenging due to the loss of photons, which grows exponentially with the distance covered. Quantum repeaters could in theory be used to extend the distances over which...journal article 2021

Lipinska, V. (author)The Internet as we know it has had an immense impact on the way we communicate. We can now do it faster and more securely than ever before. Enabling quantum communication between any two points on Earth is the next step towards even more secure communication. This is the goal of the quantum internet. Although it is hard to predict all of the...doctoral thesis 2020

Skrzypczyk, Matthew (author)Quantum networks are networks composed of quantum processors that facilitate the exchange of information in the form of quantum bits, also called qubits. Qubits observe a physical phenomenon known as entanglement that enables the transmission of quantum information over long distances as well as the realization of novel protocols and...master thesis 2020

Rabbie, Julian (author)The quantum internet will allow for communication via qubits, enabling for improved clock synchronization, blind quantum computing and quantum key distribution. Key components of such a quantum network are quantum repeaters, which help to overcome the exponential loss of photons in optical fibers. In this thesis we focus on one type of quantum...master thesis 2020

Lipinska, V. (author), Lê, P.T. (author), Ribeiro, J.D. (author), Wehner, S.D.C. (author)We consider testing the ability of quantum network nodes to execute multiround quantum protocols. Specifically, we examine protocols in which the nodes are capable of performing quantum gates, storing qubits and exchanging said qubits over the network a certain number of times. We propose a simple pingpong test, which provides a certificate...journal article 2020

Kozlowski, W. (author), Dahlberg, E.A. (author), Wehner, S.D.C. (author)The second quantum revolution brings with it the promise of a quantum internet. As the first quantum network hardware prototypes near completion new challenges emerge. A functional network is more than just the physical hardware, yet work on scalable quantum network systems is in its infancy. In this paper we present a quantum network protocol...conference paper 2020

Menon, Shankar G. (author), Singh, Kevin (author), Borregaard, J. (author), Bernien, Hannes (author)The realization of a longdistance, distributed quantum network based on quantum memory nodes that are linked by photonic channels remains an outstanding challenge.

Molengraaf, Constantijn (author)In the range of applications opened by quantum technology, often a highly entangled source state is needed as an input for a protocol (target state). The easiest example of such an application is QKD, other examples are quantum secret sharing and measurement based quantum computing. Generating a nonlocal entangled state is however not trivial....master thesis 2019
