A sparse spin qubit array with integrated control electronics
Jelmer M. Boter, Juan P. Dehollain, Jeroen P. G. van Dijk +6
Current implementations of quantum computers suffer from large numbers of control lines per qubit, becoming unmanageable with system scale up. Here, we discuss a sparse spin-qubit…
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…
Spatial Noise Correlations in a Si/SiGe Two-Qubit Device from Bell State Coherences
Jelmer M. Boter, Xiao Xue, Tobias S. Krähenmann +10
We study spatial noise correlations in a Si/SiGe two-qubit device with integrated micromagnets. Our method relies on the concept of decoherence-free subspaces, whereby we measure t…
Quantum transport properties of industrial Si/SiO
D. Sabbagh, N. Thomas, J. Torres +21
We investigate the structural and quantum transport properties of isotopically enriched Si/SiO stacks deposited on 300 mm Si wafers in an industrial CMOS fab. Hig…
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…
