1. A quantum-circuit execution process comprising:
transitioning a first molecule of a first quantum gate of a quantum circuit from a first non-Rydberg state to a first Rydberg state, the first Rydberg state having a first principal quantum number; and
transitioning a second molecule of a second quantum gate of the quantum circuit to transition from a second non-Rydberg state to a second Rydberg state, the second quantum gate being separate from the first quantum gate, the second Rydberg state having a second principal quantum number greater than the first principal quantum number wherein:
the first quantum gate is characterized by a first maximum connection distance over which molecules of the first quantum gate must, under a first plurality of certain conditions, interact, the first Rydberg state being based on the first maximum connection distance; and
the second quantum gate is characterized by a second maximum connection distance over which molecules of the first quantum gate must, under a second plurality of certain conditions, interact, the second Rydberg state being based on the second maximum connection distance, the second maximum connection distance being greater than the first maximum connection distance.
