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…
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…
Computing with spin qubits at the surface code error threshold
Xiao Xue, Maximilian Russ, Nodar Samkharadze +4
High-fidelity control of quantum bits is paramount for the reliable execution of quantum algorithms and for achieving fault-tolerance, the ability to correct errors faster than the…
Single-Hole Pump in Germanium
A. Rossi, N. W. Hendrickx, A. Sammak +3
Single-charge pumps are the main candidates for quantum-based standards of the unit ampere because they can generate accurate and quantized electric currents. In order to approach…
