The first signature of topological superconductivity is a robust zero-bias peak in tunneling conductance. We perform tunneling experiments on semiconductor nanowires (InSb) coupled to superconductors (NbTiN) and establish the zero-bias peak phase in the space of gate voltage and external magnetic field. Our findings are consistent with calculations for a finite-length topological nanowire and provide means for Majorana manipulation as required for braiding and topological quantum bits. %G English %2 https://laas.hal.science/hal-01712993/document %2 https://laas.hal.science/hal-01712993/file/e1701476.full.pdf %L hal-01712993 %U https://laas.hal.science/hal-01712993 %~ UNIV-TLSE2 %~ UNIV-TLSE3 %~ UGA %~ CNRS %~ INSA-TOULOUSE %~ INPG %~ LAAS %~ NEEL %~ UT1-CAPITOLE %~ LAAS-MPN %~ LAAS-MICRO-NANO-BIO-TECHNOLOGIES %~ NEEL-NPSC %~ INSA-GROUPE %~ UGA-COMUE %~ TOULOUSE-INP %~ UNIV-UT3 %~ UT3-INP %~ UT3-TOULOUSEINP
