A geometric formalism yields tight quantum speed limits for quantum gates by mapping unitary evolution to minimal-length curves with curvature bounds.
A quantum speed limit for observables is formulated from the trace-norm asymmetry of the time-dependent state, observable through weak measurements and bounding the quantum Fisher information for the conjugate parameter.
