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 ...

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 ...

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 ...
