Lightly-strained germanium quantum wells with hole mobility exceeding one million
M. Lodari, O. Kong, M. Rendell +5
We demonstrate that a lightly-strained germanium channel ( = -0.41%) in an undoped Ge/SiGe heterostructure field effect transistor supports a 2D h…
Atomic fluctuations lifting the energy degeneracy in Si/SiGe quantum dots
Brian Paquelet Wuetz, Merritt P. Losert, Sebastian Koelling +16
Electron spins in Si/SiGe quantum wells suffer from nearly degenerate conduction band valleys, which compete with the spin degree of freedom in the formation of qubits. Despite att…
Valley splitting in silicon from the interference pattern of quantum oscillations
M. Lodari, L. Lampert, O. Zietz +3
We determine the energy splitting of the conduction-band valleys in two-dimensional (2D) electrons confined in silicon metal oxide semiconductor (Si-MOS) Hall-bar transistors. Thes…
Simultaneous single-qubit driving of semiconductor spin qubits at the fault-tolerant threshold
W. I. L. Lawrie, M. Rimbach-Russ, F. van Riggelen +6
Practical Quantum computing hinges on the ability to control large numbers of qubits with high fidelity. Quantum dots define a promising platform due to their compatibility with se…
Fast universal quantum control above the fault-tolerance threshold in silicon
Akito Noiri, Kenta Takeda, Takashi Nakajima +4
Fault-tolerant quantum computers which can solve hard problems rely on quantum error correction. One of the most promising error correction codes is the surface code, which require…
Coherent spin-spin coupling mediated by virtual microwave photons
Patrick Harvey-Collard, Jurgen Dijkema, Guoji Zheng +3
We report the coherent coupling of two electron spins at a distance via virtual microwave photons. Each spin is trapped in a silicon double quantum dot at either end of a supercond…
