Revealing topological protection through unprotected operations in a Majorana parity qubit
Sebastian Miles, Juan Daniel Torres Luna, Francesco Zatelli +7
A recent experiment reported coherent parity oscillations between minimal Kitaev chains, demonstrating a Majorana parity qubit (arXiv:2607.09511). Operations on this qubit are cont…
Majorana parity qubit in coupled minimal Kitaev chains
Francesco Zatelli, Bart Roovers, Nick van Loo +11
Majorana zero modes provide a route to fault-tolerant qubits by encoding information non-locally in fermion parity. Their sensitivity to noise is expected to decrease exponentially…

Contemporary quantum devices are reaching new limits in size and complexity, allowing for the experimental exploration of emergent quantum modes. However, this increased complexity…
Signatures of Majorana protection in a three-site Kitaev chain
Alberto Bordin, Chun-Xiao Liu, Tom Dvir +14
Majorana zero modes (MZMs) are non-Abelian excitations predicted to emerge at the edges of topological superconductors. One proposal for realizing a topological superconductor in o…
