We are an experimental research group at the Physics and Astronomy Department at Rice University. We use individual atoms as carriers of information and control precisely their mutual interactions. For more details, please have a look at our research directions!
Our paper on trapped-ion simulation is published on Science Advances!
Our paper on the simulation of a paradigmatic model of electron transfer in the presence of tunable dissipation is now available on Science Advances. This paper encompasses aspects of chemistry, quantum optics, and atomic physics. Check it out!

Our paper on Grover-QAOA applied to SAT problem is published on QST!
We applied a new variant of QAOA (Quantum Approximate Optimization Algorithm) based on the Grover algorithm (G-QAOA) to satisfiability problems (3-SAT and Max-SAT), relevant to optimization applications. We find that G-QAOA surpasses conventional QAOA in its ability to sample all solutions and shows quadratic speedup. Check it out on Quantum Science and Technology!

Our paper on simulating electron transfer with trapped ions is on the arXiv!
We used a multi-species ion chain employing both ground-state and optical qubits to simulate a paradigmatic model of electron transfer in the presence of tunable dissipation. This paper is the result of a very fun interdisciplinary collaboration among the Physics, Chemistry, and Bioscience departments at Rice University. Check it out!

Welcome Caesar, Brian, Lucius and Kabir!
Pagano Lab welcomes a new group of undergraduates that will join the group this summer.
- Caesar (Rice University) will work on a new rectifier scheme used to stabilize the rf voltage that determines trap frequency in the trapped-ion system.
- Brian (San Jacinto College) will design and build a Faraday cage to limit the effect of environmental noise on the trap frequency.
- Lucius (USTC) will design a new filter box and work on a transfer cavity setup for locking our lasers.
- Kabir (Rice University) will work on ArtiQ to make our Rice university branch more user friendly and more integrated with NDscan.
Looking forward for a productive summer!
Congratulations Mingjian!
Pagano Lab congratulates Mingjian Zhu for graduating with the thesis entitled:
“Excitation Energy Transfer and Delocalization in Trapped-ion Quantum Simulator: A Numerical Study”.
Mingjian will start his PhD with Professor Han Pu at Rice University next Fall. Congratulations!
Welcome Mingjian, Prathik, John and Mac!
Four undergrads will join the team this summer! John will work on the ArtiQ control system, Prathik will build a small muon detector, Mac will develop a PID out of a Red Pitaya and Mingjian will help us understand how to simulate electron transfer in trapped-ion systems. It’s going to be a fun summer!
