Research Related to the Codes
We do research in quantum control, entanglement and compiling. On this site we provide codes which realize published theoretical ideas from our group but also other useful programs related to ongoing projects and unpublished results. The codes are mainly written for Wolfram Mathematica software. Feel free to use them and please send us your feedback/questions at firstname.lastname@example.org

A function that realizes best separable approximation for a mixed state of 3 qubits using the algorithm developed here. Its key ingredient is the simplex method. This permits you to decide with confidence (0.1%) whether your state is NPT entangled, PPT entangled or Separable. In addition, the Essentially Entangled Component (density matrix) is provided as well as its weight over the given density matrix which provides an simple estimation of entanglement in your state. link
Given a multipartite pure state, tanglemeter provides for a complete set of invariants under local unitary operations. This set of complex numbers is directly connected to the inseparability of state and provides a first order estimation on the entanglement of subgroups within the state. We have added a program which derives the tanglemeter’s coefficients for 3,4, 5 and 6 qubit pure states. link
