Tuning methods for semiconductor spin--qubits
Tim Botzem, Michael D. Shulman, Sandra Foletti +13
We present efficient methods to reliably characterize and tune gate-defined semiconductor spin qubits. Our methods are designed to target the tuning procedures of semiconductor dou…
Characterization of S-T Transition Dynamics via Correlation Measurements
Christian Dickel, Sandra Foletti, Vladimir Umansky +1
Nuclear spins are an important source of dephasing for electron spin qubits in GaAs quantum dots. Most studies of their dynamics have focused on the relatively slow longitudinal po…
Semi-classical model for the dephasing of a two-electron spin qubit coupled to a coherently evolving nuclear spin bath
Izhar Neder, Mark S. Rudner, Hendrik Bluhm +3
We study electron spin decoherence in a two-electron double quantum dot due to the hyperfine interaction, under spin-echo conditions as studied in recent experiments. We develop a…
Universal quantum control of two-electron spin quantum bits using dynamic nuclear polarization
Sandra Foletti, Hendrik Bluhm, Diana Mahalu +2
One fundamental requirement for quantum computation is to perform universal manipulations of quantum bits at rates much faster than the qubit's rate of decoherence. Recently, fast…
Long coherence of electron spins coupled to a nuclear spin bath
Hendrik Bluhm, Sandra Foletti, Izhar Neder +4
Qubits, the quantum mechanical bits required for quantum computing, must retain their fragile quantum states over long periods of time. In many types of electron spin qubits, the p…
Enhancing the Coherence of a Spin Qubit by Operating it as a Feedback Loop That Controls its Nuclear Spin Bath
Hendrik Bluhm, Sandra Foletti, Diana Mahalu +2
In many realizations of electron spin qubits the dominant source of decoherence is the fluctuating nuclear spin bath of the host material. The slowness of this bath lends itself to…
