QuanEstimation is a comprehensive toolbox for computation and scheme design in quantum parameter estimation. We are committed to developing this tool constantly and invoking new features.

Quantum Metrology and Control

  • Quantum phase estimations, including single and multiple phase estimations in optical interferometers.

  • Parameter estimations in atomic interferometers, such as Bose-Einstein condensate.

  • Controlled schemes to improve the precision of parameter estimations in various systems.

Foundations of Quantum Mechanics

  • Quantum speed limits. ​​

  • Quantum correlation, including the criteria, witness, and the dynamical behavior of entanglement and quantum discord.

  • Spin squeezing.
