Distinct Lifetimes for and Loop Measurements in a Majorana Tetron Device

Morteza Aghaee, Zulfi Alam, Rikke Andersen +164

We present a hardware realization and measurements of a tetron qubit device in a superconductor-semiconductor heterostructure. The device architecture contains two parallel superco…

Response to recent comments on Phys. Rev. B 107, 245423 (2023) and Subsection S4.3 of the Supp. Info. for Nature 638, 651-655 (2025)

Morteza Aghaee, Zulfi Alam, Mariusz Andrzejczuk +127

The topological gap protocol (TGP) is a statistical test designed to identify a topological phase with high confidence and without human bias. It is used to determine a promising p…

Roadmap to fault tolerant quantum computation using topological qubit arrays

David Aasen, Morteza Aghaee, Zulfi Alam +179

We describe a concrete device roadmap towards a fault-tolerant quantum computing architecture based on noise-resilient, topologically protected Majorana-based qubits. Our roadmap e…

Interferometric Single-Shot Parity Measurement in an InAs-Al Hybrid Device

Morteza Aghaee, Alejandro Alcaraz Ramirez, Zulfi Alam +159

The fusion of non-Abelian anyons or topological defects is a fundamental operation in measurement-only topological quantum computation. In topological superconductors, this operati…

Multimode optomechanical system in the quantum regime

William H. P. Nielsen, Yeghishe Tsaturyan, Christoffer B. Møller +2

We realise a simple and robust optomechanical system with a multitude of long-lived () mechanical modes in a phononic-bandgap shielded membrane resonator. An optical mode o…

Signatures of orbital loop currents in the spatially resolved local density of states

W. H. P. Nielsen, W. A. Atkinson, B. M. Andersen

Polarized neutron scattering measurements have suggested that intra-unit cell antiferromagnetism may be associated with the pseudogap phase. Assuming that loop current order is res…
