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…
Cross-Platform Autonomous Control of Minimal Kitaev Chains
David van Driel, Rouven Koch, Vincent P. M. Sietses +21
Contemporary quantum devices are reaching new limits in size and complexity, allowing for the experimental exploration of emergent quantum modes. However, this increased complexity…
Broad nonlocal spectrum in the Pb-InSb hybrid three terminals for potential realization of Kitaev chains
Guoan Li, Xiaofan Shi, Ruixuan Zhang +21
Hybrid superconductor-semiconductor(SC-SM) nanowires remain one of the foremost platforms for engineering topological superconductivity and Majorana zero modes(MZMs) towards fault-…
Compromise-Free Scaling of Qubit Speed and Coherence
Miguel J. Carballido, Simon Svab, Rafael S. Eggli +12
Across leading qubit platforms, a common trade-off persists: increasing coherence comes at the cost of operational speed, reflecting the notion that protecting a qubit from its noi…
Single-shot parity readout of a minimal Kitaev chain
Nick van Loo, Francesco Zatelli, Gorm O. Steffensen +12
Protecting qubits from noise is essential for building reliable quantum computers. Topological qubits offer a route to this goal by encoding quantum information non-locally, using…
Electrical Characterization of hexagonal SiGe
Isabelle Bollier, Federico Balduini, Marilyne Sousa +4
We report electrical measurements on hexagonal silicon-germanium (hex-SiGe), a group IV alloy with direct bandgap. Electrical contacts are formed by metal alloying and doping is ac…
