In order to scale a trapped-ion quantum computer to large numbers of qubits, it is necessary to precisely and consistently manipulate ions in space. Through the manipulation of a chain of 15 171Yb+ ions, we demonstrate the ability to arbitrarily split a chain of ions into three wells, operate on one of the wells, and merge the wells together: all while maintaining the coherence of the qubits. The implementation of such methods in existing trapped-ion systems will allow for longer and more complex quantum circuits in the near future, following recent work on quantum circuit verification [ref1], measurement-induced phase transitions [ref2], and NMR simulation [ref3].
