Abstract: | Long range Rydberg blockade interactions have the potential for efficient implementation of quantum gates between multiple
atoms. Here we present and analyze a protocol for implementation of a k-atom controlled NOT (C
k
NOT) neutral atom gate. This gate can be implemented using sequential or simultaneous addressing of the control atoms which
requires only 2k + 3 or 5 Rydberg π pulses respectively. A detailed error analysis relevant for implementations based on alkali atom Rydberg states is provided
which shows that gate errors less than 10% are possible for k = 35. |
