20 Second Parity Lifetime in an InAs--Pb Tetron Device
Morteza Aghaee, Zulfi Alam, Mariusz Andrzejczuk +162
A central promise of topological quantum computing is that increasing the excitation gap improves device performance significantly. Here, we experimentally validate this principle…
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…
Spin-split superconductivity in spin-orbit coupled hybrid nanowires with ferromagnetic barriers
J. Zhao, A. Mazanik, D. Razmadze +4
We report transport studies of hybrid Josephson junctions based on semiconducting InAs nanowires with fully overlapping epitaxial ferromagnetic insulator EuS and superconducting Al…
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…
Supercurrent transport through 1-periodic full-shell Coulomb islands
D. Razmadze, R. Seoane Souto, E. C. T. O'Farrell +4
We experimentally investigate supercurrent through Coulomb islands, where island and leads are fabricated from semiconducting nanowires with fully surrounding superconducting shell…
Supercurrent reversal in ferromagnetic hybrid nanowire Josephson junctions
D. Razmadze, R. Seoane Souto, L. Galletti +7
We report supercurrent transport measurements in hybrid Josephson junctions comprised of semiconducting InAs nanowires with epitaxial ferromagnetic insulator EuS and superconductin…
Electrostatic control of quasiparticle poisoning in a hybrid semiconductor-superconductor island
H. Q. Nguyen, D. Sabonis, D. Razmadze +8
The performance of superconducting devices is often degraded by the uncontrolled appearance and disappearance of quasiparticles, a process known as poisoning. We demonstrate electr…
