20 Second Parity Lifetime in an InAs--Pb Tetron Device
Morteza Aghaee, Zulfi Alam, Mariusz Andrzejczuk +162
A central promise of topological quantum computing is that increasing the excitation gap improves device performance significantly. Here, we experimentally validate this principle…
InAs-Al Hybrid Devices Passing the Topological Gap Protocol
Morteza Aghaee, Arun Akkala, Zulfi Alam +124
We present measurements and simulations of semiconductor-superconductor heterostructure devices that are consistent with the observation of topological superconductivity and Majora…
High-fidelity two-qubit gates in silicon above one Kelvin
L. Petit, M. Russ, H. G. J. Eenink +4
Spin qubits in quantum dots define an attractive platform for scalable quantum information because of their compatibility with semiconductor manufacturing, their long coherence tim…
Spin relaxation benchmarks and individual qubit addressability for holes in quantum dots
W. I. L. Lawrie, N. W. Hendrickx, F. van Riggelen +5
We investigate hole spin relaxation in the single- and multi-hole regime in a 2x2 germanium quantum dot array. We use radiofrequency (rf) charge sensing and observe Pauli Spin-Bloc…
A single-hole spin qubit
N. W. Hendrickx, W. I. L. Lawrie, L. Petit +3
Qubits based on quantum dots have excellent prospects for scalable quantum technology due to their inherent compatibility with standard semiconductor manufacturing. While early on…
Universal quantum logic in hot silicon qubits
L. Petit, H. G. J. Eenink, M. Russ +5
Quantum computation requires many qubits that can be coherently controlled and coupled to each other. Qubits that are defined using lithographic techniques are often argued to be p…
Quantum Dot Arrays in Silicon and Germanium
W. I. L. Lawrie, H. G. J. Eenink, N. W. Hendrickx +15
Electrons and holes confined in quantum dots define an excellent building block for quantum emergence, simulation, and computation. In order for quantum electronics to become pract…
Tunable coupling and isolation of single electrons in silicon metal-oxide-semiconductor quantum dots
H. G. J. Eenink, L. Petit, W. I. L. Lawrie +3
Extremely long coherence times, excellent single-qubit gate fidelities and two-qubit logic have been demonstrated with silicon metal-oxide-semiconductor spin qubits, making it one…
Spin lifetime and charge noise in hot silicon quantum dot qubits
L. Petit, J. M. Boter, H. G. J. Eenink +10
We investigate the magnetic field and temperature dependence of the single-electron spin lifetime in silicon quantum dots and find a lifetime of 2.8 ms at a temperature of 1.1 K. W…
A Crossbar Network for Silicon Quantum Dot Qubits
R. Li, L. Petit, D. P. Franke +10
The spin states of single electrons in gate-defined quantum dots satisfy crucial requirements for a practical quantum computer. These include extremely long coherence times, high-f…
