Description
In the past few years Germanium has attracted lot of attention as a platform for spin qubits, due to the low effective mass, strong spin orbit interaction, which allows electrically driven spin qubits, and its potential for co-integration with superconducting technology.
From 2018 and within just three years a Loss-DiVincenzo (LD), a singlet-triplet hole spin qubit, two-qubit gate devices and a four-qubit Ge quantum processor have been realized demonstrating the potential of Ge for quantum information. However, long-distance qubit coupling remains a significant challenge. Superconducting resonators play a prominent role in realizing high fidelity distant two-qubit gates. In this talk I will present our results on Ge hole spin qubits, at fields compatible with Al technology.
