Simulation of Kitaev model using one-dimensional chain of superconducting qubits and environmental effect on topological states
Kitaev fermionic chain is one of the important physical models for studying topological physics and quantum computing. We here propose an approach to simulate the one-dimensional Kitaev
Gatemon qubit based on a thin InAs-Al hybrid nanowire
We study a gate-tunable superconducting qubit (gatemon) based on a thin InAs-Al hybrid nanowire. Using a gate voltage to control its Josephson energy, the gatemon can reach the strong
