Dispersive measurement of a semiconductor double quantum dot via 3D integration of a high-impedance TiN resonator
Nathan Holman, D. Rosenberg, D. Yost +5
Spins in semiconductor quantum dots are a candidate for cryogenic quantum processors due to their exceptionally long coherence times. One major challenge to scaling quantum dot spi…
Majorana bound states in nanowire-superconductor hybrid systems in periodic magnetic fields
Viktoriia Kornich, Maxim G. Vavilov, Mark Friesen +2
We study how the shape of a periodic magnetic field affects the presence of Majorana bound states (MBS) in a nanowire-superconductor system. Motivated by the field configurations t…
Signatures of atomic-scale structure in the energy dispersion and coherence of a Si quantum-dot qubit
J. C. Abadillo-Uriel, Brandur Thorgrimsson, Dohun Kim +11
We report anomalous behavior in the energy dispersion of a three-electron double-quantum-dot hybrid qubit and argue that it is caused by atomic-scale disorder at the quantum-well i…
Coherent Quantum Oscillations in a Silicon Charge Qubit
Zhan Shi, C. B. Simmons, Daniel. R. Ward +10
Fast quantum oscillations of a charge qubit in a double quantum dot fabricated in a Si/SiGe heterostructure are demonstrated and characterized experimentally. The measured inhomoge…
Si/SiGe quantum dot with superconducting single-electron transistor charge sensor
Mingyun Yuan, Feng Pan, Zhen Yang +6
We report a robust process for fabrication of surface-gated Si/SiGe quantum dots (QDs) with an integrated superconducting single-electron transistor (S-SET) charge sensor. A combin…
Enhancement mode double top gated MOS nanostructures with tunable lateral geometry
E. P. Nordberg, G. A. Ten Eyck, H. L. Stalford +11
We present measurements of silicon (Si) metal-oxide-semiconductor (MOS) nanostructures that are fabricated using a process that facilitates essentially arbitrary gate geometries. S…
