While GaAs structures represent the current state-of-the art in device complexity, Si devices
hold the current records in coherence times due to the nuclear-spin free environment in
isotopically purified samples. Ge which has been much less studied, has recently emerged as
a very promising material platform for hosting spin qubits due to the suppressed hyperfine
interaction and strong spin orbit coupling. In only three years a single Loss-DiVincenzo qubit,
2-qubit and most recently even 4-qubit devices have been demonstrated.
In the Nanoelectronics group of Georgios Katsaros we have recently realized a hole spin qubit
with dephasing times of 1 μs operating already at fields of 500μT, within the range of magnetic
fields currently used for on-chip biasing of superconducting circuits. This was achieved by
using the large out of plane g-factors of holes in Ge and by encoding the qubit in the singlettriplet
states of a double quantum dot device. In this project we aim to use hole qubits in planar
Ge devices and make further steps towards the realization of a hole spin based quantum
processor. More information: nanoelectronicsgroup.wordpress.com
