Pure quantum states can be stabilized in open systems subject to external driving forces and dissipation by environmental modes. We show that driven dissipative (DD) Majorana devices offer key advantages for stabilizing degenerate state manifolds ("dark spaces") manipulating dark spaces, both with respect native (non-DD) DD platforms topologically trivial building blocks. For two tunnel-coupled boxes, using otherwise only standard hardware elements (e.g., a noisy electromagnetic environment...
An important ingredient in the quest for a quantum information toolbox is to provide protection elementary bits and arrays thereof. Here, authors show that combining topological features of Majorana-based qubits protected dark states drive dissipation protocols gives rise an exceptionally good performance. For single qubit device, arbitrary pure can be stabilized. Two setups support space manifolds, facilitating stabilization fault-tolerant Bell states. Once working Majorana platform becomes...
Mesoscopic superconducting islands with four or more Majorana zero modes are promising candidates for topological qubits. In recent theoretical proposals, interlinked ensembles of such boxes used to establish code networks that, in principle, can run large-scale quantum computations and error correction. Here, the authors discuss transport through coupled boxes, developing approaches which general be drastically reduced their complexity. This is followed by a discussion several examples...
