Abstract:
In this talk, I will talk about two recent works on quantum gates for circuit-based 
quantum computation and multipartite entangled states for one-way quantum computation 
using neutral atoms. In the first work, we have studied the high-fidelity Cz gates with 
time-optimal pulses, which is crucial for deep quantum circuits which require high 
enough gate fidelity. The second work focuses on generation of graph states in an atom-
nanophotonic interface, where multipartite entangled states are the essential resource 
for measurement-based quantum computation with only single-qubit measurements. We 
utilize the state carving technique to create these scalable graph states, which can be 
useful for problem-specific applications
