Low dephasing and robust micromagnet designs for silicon spin qubits
N. I. Dumoulin Stuyck, F. A. Mohiyaddin, R. Li +3
Using micromagnets to enable electron spin manipulation in silicon qubits has emerged as a very popular method, enabling single-qubit gate fidelities larger than 99:9%. However, th…
A flexible 300 mm integrated Si MOS platform for electron- and hole-spin qubits exploration
R. Li, N. I. Dumoulin Stuyck, S. Kubicek +12
We report on a flexible 300 mm process that optimally combines optical and electron beam lithography to fabricate silicon spin qubits. It enables on-the-fly layout design modificat…
Demonstration of nonstoquastic Hamiltonian in coupled superconducting flux qubits
I. Ozfidan, C. Deng, A. Y. Smirnov +45
Quantum annealing (QA) is a heuristic algorithm for finding low-energy configurations of a system, with applications in optimization, machine learning, and quantum simulation. Up t…
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…
Gate-controlled quantum dots and superconductivity in planar germanium
