    "abstract": "We propose a scheme to implement arbitrary-speed quantum entangling gates on\ntwo trapped ions immersed in a large linear crystal of ions, with minimal\ncontrol of laser beams. For gate speeds slower than the oscillation frequencies\nin the trap, a single appropriately-detuned laser pulse is sufficient for\nhigh-fidelity gates. For gate speeds comparable to or faster than the local ion\noscillation frequency, we discover a five-pulse protocol that exploits only the\nlocal phonon modes. This points to a method for efficiently scaling the ion\ntrap quantum computer without shuttling ions.",
