An interactive quantum spin simulator with full visualization of spin operator dynamics using the DROPS representation.
Current release: v2.2.0
See the complete quantum state of multi-spin systems using the Discrete Representation of Operators for Spin Systems.
Load, edit, and simulate NMR/ESR pulse sequences in real time. Watch the spin dynamics unfold step by step.
Optimize pulse sequences with gradient descent, conjugate gradient, or interior-point methods. Design robust broadband pulses.
Simulate ensembles of spin systems with varying offsets, couplings, and relaxation to study robustness and design tolerant sequences.
Runs on iOS, Android, macOS, Linux, Windows, and in the browser. Same simulation engine everywhere.
Free for research and education. Developed at the Technical University of Munich by the Glaser Group.
