Filter function formalism beyond pure dephasing and non-Markovian noise in singlet-triplet qubits
Edwin Barnes, Mark S. Rudner, Frederico Martins +3
The filter function formalism quantitatively describes the dephasing of a qubit by a bath that causes Gaussian fluctuations in the qubit energies with an arbitrary noise power spec…
Noise suppression using symmetric exchange gates in spin qubits
Frederico Martins, Filip K. Malinowski, Peter D. Nissen +6
We demonstrate a substantial improvement in the spin-exchange gate using symmetric control instead of conventional detuning in GaAs spin qubits, up to a factor-of-six increase in t…
Formation of quantum dots in the potential fluctuations of InGaAs heterostructures probed by scanning gate microscopy
P. Liu, F. Martins, B. Hackens +6
The disordered potential landscape in an InGaAs/InAlAs two-dimensional electron gas patterned into narrow wires is investigated by means of scanning gate microscopy. It is found th…
