Theoretical modeling demonstrates dark space stabilization in driven dissipative Majorana qubits, suggesting a hardware-efficient route to fault-tolerant quantum computing.
An important ingredient in the quest for a quantum information toolbox is to provide protection to elementary quantum bits and arrays thereof. Here, the authors show that combining the topological features of Majorana-based qubits and protected dark states of drive and dissipation protocols gives rise to an exceptionally good performance. For a single qubit device, arbitrary pure states can be stabilized. Two qubit setups support protected dark space manifolds, facilitating stabilization of fault-tolerant Bell states. Once a working Majorana platform becomes available, only standard hardware requirements would be needed to implement these schemes.
