Fast spin exchange between two distant quantum dots
Filip K. Malinowski, Frederico Martins, Thomas B. Smith +8
The Heisenberg exchange interaction between neighboring quantum dots allows precise voltage control over spin dynamics, due to the ability to precisely control the overlap of orbit…
Spin of a multielectron quantum dot and its interaction with a neighboring electron
Filip K. Malinowski, Frederico Martins, Thomas B. Smith +8
We investigate the spin of a multielectron GaAs quantum dot in a sequence of nine charge occupancies, by exchange coupling the multielectron dot to a neighboring two-electron doubl…
Negative spin exchange in a multielectron quantum dot
Frederico Martins, Filip K. Malinowski, Peter D. Nissen +5
By operating a one-electron quantum dot (fabricated between a multielectron dot and a one-electron reference dot) as a spectroscopic probe, we study the spin properties of a gate-c…
Symmetric Operation of the Resonant Exchange Qubit
Filip K. Malinowski, Frederico Martins, Peter D. Nissen +5
We operate a resonant exchange qubit in a highly symmetric triple-dot configuration using IQ-modulated RF pulses. At the resulting three-dimensional sweet spot the qubit splitting…
Spectrum of the Nuclear Environment for GaAs Spin Qubits
Filip K. Malinowski, Frederico Martins, Łukasz Cywiński +7
Using a singlet-triplet spin qubit as a sensitive spectrometer of the GaAs nuclear spin bath, we demonstrate that the spectrum of Overhauser noise agrees with a classical spin diff…
Notch filtering the nuclear environment of a spin qubit
F. K. Malinowski, F. Martins, P. D. Nissen +8
Electron spins in gate-defined quantum dots provide a promising platform for quantum computation. In particular, spin-based quantum computing in gallium arsenide takes advantage of…
