The effects of alloy disorder on strongly-driven flopping mode qubits in Si/SiGe
Merritt P. R. Losert, Utkan Güngördü, S. N. Coppersmith +2
In Si quantum dot systems, large magnetic field gradients are needed to implement spin rotations via electric dipole spin resonance (EDSR). By increasing the effective electron dip…
Anisotropy reduction and tunability of hole-spin qubit g-factor in strained parabolic Ge/SiGe quantum wells
R. K. L. Colmenar, Arthur Lin, Omadillo Abdurazakov +3
Hole-spin qubits in planar Ge/SiGe heterostructures have attracted significant attention in recent years owing to their favorable electrical characteristics and prolonged coherence…
Quantum dynamics of semiconductor quantum dot Josephson junctions
Utkan Güngördü, Rusko Ruskov, Silas Hoffman +3
Josephson junctions constructed from superconductor-semiconductor-superconductor heterostructures have been used to realize a variety of voltage-tunable superconducting quantum dev…
Ultra-dispersive resonator readout of a quantum-dot qubit using longitudinal coupling
Benjamin Harpt, J. Corrigan, Nathan Holman +10
We perform readout of a quantum-dot hybrid qubit coupled to a superconducting resonator through a parametric, longitudinal interaction mechanism. Our experiments are performed with…
Opinion: The simplest quantum computer
Charles Tahan
Instead of writing a review article on the state of the field, I'm going to instead write a retrospective from the year 2040. I'll tell you how this whole "quantum computing thing"…
