Arbitrary-speed quantum gates within large ion crystals through minimum control of laser beams
Arbitrary-speed quantum gates within large ion crystals through minimum control of laser beams
We propose a scheme to implement arbitrary-speed quantum entangling gates on two trapped ions immersed in a large linear crystal of ions, with minimal control of laser beams. For gate speeds slower than the oscillation frequencies in the trap, a single appropriately-detuned laser pulse is sufficient for high-fidelity gates. For …
