An adiabatic quantum algorithm may lose quantumness such as quantum coherence entirely in its long runtime and consequently the expected quantum speedup of the algorithm does not show up. Here we ...

Quantum mechanics offers unprecedented possibilities to transmit and process information that have the potential to revolutionize information and communication technologies. While many such advantages ...

Quick verification A quantum computer has been shown to be faster than a classical one at verifying the solution to an NP-complete problem when provided with only a ...
