A Degenerate Singlet-Triplet Qubit with All-Electrical Orthogonal Control
Phuong X. Nguyen, Konstantinos Tsoukalas, Jann H. Ungerer +8
The paper demonstrates an all‑electrical method to achieve orthogonal control of a degenerate singlet‑triplet qubit formed by two hole spins in a germanium double quantum dot, enab…

Large quantum dot energy level shifts in anomalous photon-assisted tunneling
Jared Benson, C. E. Sturner, A. R. Huffman +12
Orbital energy splittings are important quantum dot parameters for the operation of hole spin qubits. They are known to depend on the lateral confinement of the quantum dots. Howev…
