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…

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…

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…
