Why are quantum computing networks so far behind classical methods?

I'm new to quantum computing, and computing in general, but it seems like quantum computing networks are really lagging behind what we have achieved with classical networks. I know that there are ...

Is it ever beneficial to communicate qubits that aren't EPR pairs?

When Alice wants to send a qubit $q$ to Bob, she doesn't have to send $q$ itself. She can instead generate an EPR pair $(a, b)$, send $b$ to Bob, and teleport $q$ to Bob by consuming $(a,b)$ and ...

Entanglement for Byzantine fault problem

In "Proof of Work"-Blockchains, the block is added by the member who first solves a hard problem. That's very expensive. But if all blockchain-members get an entangled dice, that randomly ...

Why do quantum networks matter?

I'm very new to quantum computing, sorry if this is a dumb question. I was reading in some lecture notes I found online that a quantum network could be created by using teleportation multiple times to ...

Simulating a Quantum Network over a real Classical Network Using Simulaqron

I'm trying to simulate a quantum network over a real classical network using the Simulaqron framework. I know the documentations says this is possible but I am having trouble finding examples of how ...

Changing qubits coefficients to trigonometric functions in Grover Algorithm

In this paper, in Appendix B.1 (Grover's Search Algorithm and Grover Operator G), it does a change of coefficients, such as what is done for the Bloch Sphere, but for a many qubits system using only ...

Are there emulators for quantum networks?

Inspired by the question Are there emulators for quantum computers?, I'm curious to know if it's possible to emulate a quantum network on a classic computer. Additionally, is it possible to emulate a ...

Three sender quantum simultaneous decoder conjecture

Recently I have started to read about network quantum information theory, where network problems are studied under the classical-quantum channel. For example, capacities of the cq-MAC, cq-broadcast or ...

How to you encode a network as an adjacency-list in the quantum-gate model?

I have a network problem that I believe would be represented as an adjacency-list on a quantum circuit. Typically, the list is up for traversing from various perspectives (e.g., shortest-path between ...
