Abstract
We investigated the quantum transport in InAs nanowires. From the universal conductance fluctuations at 0.5 K a phase-coherence length of 300 nm was extracted. By averaging the gate-dependent conductance fluctuations a magnetoconductance peak due to weak antilocalization was found indicating the presence of spin-orbit coupling. In a nanowire quantum dot formed by three gate fingers single electron tunneling was confirmed
