Tetron Qubit Device Demonstrates Widely Separated Decoherence Times for Pauli-X and Pauli-Z Measurements
This paper details the experimental realization and characterization of a tetron qubit, a superconducting-semiconductor heterostructure incorporating four Majorana zero modes. The authors present single-shot interferometric measurements for both Pauli-X and Pauli-Z loops, critical for understanding qubit coherence. The research identifies vastly different lifetimes for these measurements, revealing insights into distinct decoherence mechanisms within the device.
