Center for Quantum Research and Technology (CQRT)
Congratulations to CQRT/P&A faculty: Madalina Furis, Ian Sellers, and Joseph Tischler on winning prestigious NSF award!
Madalina Furis, Ph.D. a professor of CQRT / Physics & Astronomy at the Univ of Oklahoma (OU), and Matthew White, Ph.D., associate professor of Physics and Materials Science at the Univ. of Vermont (UVM) lead an interdisciplinary team of eight scientists who just received 1.5 million dollars in funding from NSF to establish a Partnership for International Research and Education (PIRE) program in collaboration with scientists at the Yamagata and Osaka universities in Japan.
The two PIs and their collaborators, Profs. David Punihaole (UVM-Chemistry), Jihong Ma (UVM- Mechanical Engineering), Kyle Ikeda (UVM- Asian Languages and Literature), Ian Sellers (OU- CQRT / Physics & Astronomy), Joseph Tischler (OU- CQRT / Physics & Astronomy) and Binbin Weng (OU- Electrical Engineering) will investigate harvesting, storing, and transferring of energy in soft electronic materials for cost-effective, high-throughput photovoltaics and flexible electronics applications, while training international scientists and promoting intercultural exchange. This partnership will bring the US-based participants unprecedented access to the remarkable soft-materials and optoelectronic device fabrication, characterization facilities, and extensive connections with the semiconductor industries of tomorrow.
In addition to research support, the program offers a generous summer stipend for an international research experience geared towards undergraduate physics, chemistry, and engineering undergraduate students recruited from four-year academic institutions of the researchers’ home states. The OU faculty will focus on recruitment among the tribal and rural institutions of Oklahoma, in order to find and support a diverse pool of the most promising talents in our state. The students will also benefit from language and culture training that will enable them to navigate the waters of international collaborative research in their future careers. This program will represent the crucible for the birth of a Global Scientist Certificate at both institutions.
Congratulations to Professors Doerte Blume, Grant Biedermann and Alberto Marino for winning a competitive research grant from the W. M. Keck Foundation!
We’d like to congratulate our team of professors Doerte Blume, Grant Biedermann, and Alberto Marino on being awarded a grant of $1m from the W. M. Keck Foundation. W. M. Keck Foundation grant programs are highly competitive and support only pioneering discoveries in science, engineering, and medical research that will save lives, provide innovative solutions, and add to our understanding of the world. Winning this grant by our team led by Prof Doerte Blume is a big step forward in achieving the goal of synchronizing different degrees of freedom, their spin and motional degrees of freedom, and modeling the complexity at the quantum level.
The team hopes to better understand how collective interactions emerge by creating couplings between the spins of two atoms side-by-side and coupling the motion of another set of atoms. Promising results can be developed via the grant in 3 years, which will contribute to the development of a quantum network.
The Centre for Quantum Research and Technology is very proud of Prof Doerte Blume, Prof Grant Biedermann, and Prof Marino’s success.

An Ultra- low energy organic Memristor for Brain- like Electronics
Prof. Venkatesan and his team published a paper in Nature on September 3rd reporting on an organic electronic device that can make multiple decisions (as many as 71) as opposed to just two for a silicon transistor. Besides consuming ultra- low energy, these devices may enable simpler circuits that would be ideally suited for executing tasks that are suited for artificial intelligence and machine learning or brain- like electronics.

Nature Physics article out: Dynamics of the weakly bound helium dimer
OU postdoc Qingze Guan and Blume collaborated with Maksim Kunitski, Reinhard Doerner and others from Frankfurt University and the GSI in Darmstadt on the helium dimer. The helium dimer is one of the most weakly-bound “naturally” occurring molecules. Since it’s so weakly bound, the preparation and manipulation of this fascinating molecule are rather tricky. Unless you isolate the dimer and are extremely careful, it tends to fall apart… Maksim and coworkers set up an ingeneous molecular beam experiment and used femto-second lasers to probe the system. The theory calculations by Qingze do not only match the experimental data, without a single adjustable parameter, but additionally provide unique insights. Check out the article entitled “Ultrafast manipulation of the weakly bound helium dimer”, which just appeared in Nature Physics, and the accompanying “News & Views” highlight entitled “Gently stirred not shaken” by Daniel Rolles.
Marino receives DOE grant for quantum enhanced fiber sensing
An interdisciplinary collaborative effort led by Alberto Marino involving Louisiana State University and Oak Ridge National Laboratory was funded by DOE. The initiative will leverage recent developments in quantum information science in sensing. The project will aim at improving current commercial techniques for leakage detection in the oil and gas industry by using quantum states of light to enhance the sensitivity of fiber optic sensors beyond the classical limit. The goal is to outperform the sensitivity of available state-of -the art techiques by one or two orders of magnitude. More information can be found here.

OU-WSU paper highlighted in Physical Review A
A joint theory-experiment paper by the Blume group from OU and the Engels group from Washington State University (WSU) was selected as an Editors' Suggestion by Physical Review A. The theory efforts were spearheaded by OU postdoc Dr. Qingze Guan and the experimental data were taken by Thomas Bersano and Dr. Sean Mossman, both from WSU. The work explores two realizations of a two-state model in a rubidium Bose-Einstein condensate, realized through Raman coupling of hyperfine states and lattice coupling in momentum space. The difference in the two realizations is highlighted by a particularly important role of interactions in the lattice coupling case. The work can be accessed at the APS website: https://journals.aps.org/pra/abstract/10.1103/PhysRevA.101.063620.

Presidential Dream Course on Quantum Hybrid Systems
A second quantum technology revolution is upon us! The first used the laws of quantum physics to design systems in which the energy is “quantized,” to allow only certain values. This idea is at the heart of technology ranging from TV remotes to supercomputers. Now, two other features of quantum mechanics, entanglement and superposition, are becoming accessible to control. To do so we must unite the incredible delicacy and uniformity of single atoms with the robust control and reproducibility of larger devices, forming “quantum hybrid systems.”
This Presidential Dream course will give students competence in the fundamentals so that they may pursue research and careers in this field. As part of the course world experts will come to OU to give lectures and meet with students.
