New Application Note: Optically Detected Magnetic Resonance: Quantum Spin Probe of Single Charge Dynamics

| on 30 December 2024

At Swabian Instruments, we’re excited to announce a new application note in collaboration with the Awschalom Group at the University of Chicago: “Optically Detected Magnetic Resonance: Quantum Spin Probe of Single Charge Dynamics.” This collaborative work showcases the power of advanced quantum measurement techniques using our Pulse Streamer 8/2 and Time Tagger 20 .

Quantum spin probe of single charge dynamics

Dopants in semiconductors, such as nitrogen-vacancy (NV) centers in diamond, are crucial for modern quantum applications. These centers allow precise manipulation of spin states and interactions with nearby “dark spins.” While these interactions can cause decoherence, they also open doors for advancements in quantum sensing and memory technologies. Advanced optically detected magnetic resonance (ODMR) measurements such as double electron‐electron resonance (DEER) and Hartmann-Hahn resonance are used to explore these dynamics. These techniques require the precise and synchronized generation of microwave and optical pulse sequences, which is where Swabian Instruments’ tools come in.

The Role of the Pulse Streamer 8/2 in Advanced ODMR Experiments

The Pulse Streamer 8/2 was a critical tool for this research, providing the flexibility to generate synchronized sequences with the required precision. This allowed the Awschalom Group to control complex ODMR experiments and conduct measurements with reliability and accuracy.

While the experiments were conducted at room temperature, the Pulse Streamer’s capabilities remain independent of operating temperatures. Its ability to easily execute complex pulse sequences is what makes it a valuable asset in cutting-edge quantum research.

We’re proud to support pioneering research teams like the Awschalom Group in their exploration of quantum systems.
