Optimal Approximate Quantum Conversion from a Taut-String Principle in Majorization-Based Resource Theories
Optimal approximate state conversion is a fundamental task in quantum resource theories, yet existing solutions are largely tailored to specific distinguishability measures and resource theories. We show that every optimal approximate-conversion problem in the three paradigmatic majorization-based quantum resource theo...
