What is "quantum internet" and what is its relation with quantum entanglement?

Quantum internet is a theoretical concept of global (or at least wide) quantum net. It would allow to interconnect many quantum processors (or computers) and enable them to communicate each other. ...

Does the no-cloning theorem impose limits on the capabilities of quantum networks?

Setting aside the practical problems in actually building such things, quantum computers/networks can do everything their classical counterparts do without any fundamental overhead. Your reasoning ...

Entanglement for Byzantine fault problem

There are two questions here: Is there some king of protocol which would allow to mine a block and ensure consensus using an entangled state? What will be the impact of quantum computing on the ...

How could a quantum network be constructed to handle 10,000 clients concurrently?

Enabling network sockets to handle 10k clients at the same time with over 1 gigabit per second Ethernet (the C10k problem), is different from making a quantum computer that can handle 10k qubits ...

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

Say you have $m$ vertices and the longest list you can build is of size $n$. The simplest way I could think of is an encoding in basis state like : $$ | \text{origin} \rangle | v_0 (\text{origin})\...

Changing qubits coefficients to trigonometric functions in Grover Algorithm

We know that the Initial state $|\psi\rangle$ can be represented as $\sin\frac{\theta}{2}|\chi\rangle + \cos\frac{\theta}{2}|\xi\rangle$. We can prove the result $G^R|\psi\rangle = \sin\frac{(2R+1)\...

Why do quantum networks matter?

Indeed a better strategy is to create an entangled state between A and D, then use teleportation to transfer any quantum state from A to D. Creating such a long range entanglement may require an ...
