Open AccessA single hole spin with enhanced coherence in natural silicon
Semiconductor spin qubits based on spin–orbit states are responsive to electric field excitations, allowing for practical, fast and potentially scalable qubit control. Spin electric susceptibility, however, re...

Strong photon coupling to the quadrupole moment of an electron in a solid-state qubit
The fundamental concept of light–matter interaction is routinely realized by coupling the quantized electric field in a cavity to the dipole moment of a real or an artificial atom. A recent proposal1,2, motivated...

Open AccessEnhancing the dipolar coupling of a S-T0 qubit with a transverse sweet spot
A fundamental challenge for quantum dot spin qubits is to extend the strength and range of qubit interactions while suppressing their coupling to the environment, since both effects have electrical origins. Ke...
