Robust preparation and manipulation of protected qubits using time--varying Hamiltonians

TL;DR

This paper demonstrates that protected qubits can be reliably initialized and manipulated using time-varying Hamiltonians, with topological protection remaining effective under realistic noise conditions, supported by numerical simulations.

Contribution

It introduces a method for deterministic initialization and manipulation of protected qubits via time-dependent Hamiltonians, leveraging system symmetries.

Findings

Topological protection persists under realistic noise conditions.

Numerical simulations confirm the effectiveness of the proposed method.

Protection remains robust during both initialization and manipulation phases.

Abstract

We show that it is possible to initialize and manipulate in a deterministic manner protected qubits using time varying Hamiltonians. Taking advantage of the symmetries of the system, we predict the effect of the noise during the initialization and manipulation. These predictions are in good agreement with numerical simulations. Our study shows that the topological protection remains efficient under realistic experimental conditions.
