Locking electron spins into magnetic resonance by electron-nuclear feedback
I. T. Vink, K. C. Nowack, F. H. L. Koppens +3
The main obstacle to coherent control of two-level quantum systems is their coupling to an uncontrolled environment. For electron spins in III-V quantum dots, the random environmen…
Multiple Nuclear Polarization States in a Double Quantum Dot
J. Danon, I. T. Vink, F. H. L. Koppens +3
We observe multiple stable states of nuclear polarization in a double quantum dot under conditions of electron spin resonance. The stable states can be understood within an elabora…
In situ reduction of charge noise in GaAs/AlGaAs Schottky-gated devices
Christo Buizert, Frank H. L. Koppens, Michel Pioro-Ladriere +5
We show that an insulated electrostatic gate can be used to strongly suppress ubiquitous background charge noise in Schottky-gated GaAs/AlGaAs devices. Via a 2-D self-consistent si…
A cryogenic amplifier for fast real-time detection of single-electron tunneling
I. T. Vink, T. Nooitgedagt, R. N. Schouten +2
We employ a cryogenic High Electron Mobility Transistor (HEMT) amplifier to increase the bandwidth of a charge detection setup with a quantum point contact (QPC) charge sensor. The…
Detection of single electron spin resonance in a double quantum dot
F. H. L. Koppens, C. Buizert, I. T. Vink +4
Spin-dependent transport measurements through a double quantum dot are a valuable tool for detecting both the coherent evolution of the spin state of a single electron as well as t…
High fidelity measurement of singlet-triplet states in a quantum dot
T. Meunier, K-J. Tielrooij, I. T. Vink +5
We demonstrate experimentally a read-out method that distinguishes between two-electron spin states in a quantum dot. This scheme combines the advantages of the two existing mechan…
