Researchers take a step towards achieving topological qubits in graphene

Researchers from Spain, Finland and France have demonstrated that magnetism and superconductivity can coexist in graphene, opening a path towards graphene-based topological qubits. However, designing and controlling topological qubits has remained a problem, largely due to the difficulty of finding materials…

Aalto University: A path to graphene topological qubits

In particular, by carefully controlling Yu-Shiba-Rusinov states, topological superconductivity and Majorana states can be created. However, the coexistence of magnetism and superconductivity has remained elusive in graphene, despite long-standing experimental efforts that demonstrated the existence of these two states independently. In particular, topological…

A path to graphene topological qubits

However, designing and controlling topological qubits has remained a critically open problem, ultimately due to the difficulty of finding materials capable of hosting these states, such as topological superconductors. In particular, by carefully controlling Yu-Shiba-Rusinov states, topological superconductivity and Majorana states can be created. However,…

Physicists solve centuries-old brachistochrone problem for complex quantum operations – Physics World

The work, which is detailed in Physical Review X, has implications for quantum computing, Alberti says. These variations, or “wiggling”, effectively cancelled out the effects of the transitions to the several intermediate states the atom had to go through…
