Streszczenie

Usually, two well-defined quantum states that encode a qubit need to have split energy levels for manipulation and readout purposes. In contrast, in our recent works [1,2] we show how to encode qubit in the Floquet quasi-energy structure occurring in periodically driven systems with degenerate instantaneous spectrum. Although there are many platforms realizing qubits, we set our ideas in the perspective of the solid-state systems, which recently are at the forefront of research because of their long coherence times, scalability, and a natural compatibility with semiconductor manufacturing technologies. Specifically, in my presentation I will theoretically demonstrate how to leverage non-Abelian Berry phases for quantum computing on the solid-state qubits realized by either hole-spin 3/2 [1] or electron confined to a quantum dot [2], experiencing time-dependent electric fields and immersed in the QED cavity.
