Zihe Chen Awarded Distinguished Graduate Fellowship



Zihe ChenPhysics graduate student Zihe Chen has been selected to receive an OSU Foundation Distinguished Graduate Fellowship for the 2018-19 academic year. Zihe is a member of Dr. Yingmei Liu's Atomic, Molecular, and Optical physics group. The fellowship, sponsored by the OSU Foundation and Graduate College, recognizes outstanding graduate students and provides an annual $2,500 award for educational expenses.


Quantum Walk in Momentum Space with a Bose-Einstein Condensate



Quantum Walk ReversalClassical random walks play a key role in modeling stochastic processes and represent a basic component of diffusion phenomena and nondeterministic motion. They have applications in fields as diverse as astronomy, solid-state physics, polymer chemistry, biology, and computer science. The hope is that quantum versions of random walks can lead to applications unavailable classically. Of particular note is the possibility of using quantum walks in probabilistic algorithms for universal quantum computing. The concept of a classical random walk can be translated into a quantum random walk using the entanglement between different degrees of freedom. In quantum walks, one degree of freedom acts as the “coin” which determines the direction of the walk which occurs in the other degree of freedom. However, a quantum coin can produce a superposition of two (or more states) and therefore the corresponding walk is heavily influenced by the entanglement between the coin and the walk degrees of freedom. In the experiments in Summy’s lab, the “walker” is a Bose-Einstein condensate of rubidium atoms which interacts with a series of microwave and laser pulses to move through momentum space. These experiments represent the first time a quantum walk has been realized in momentum, an important milestone in the creation of multi-dimensional quantum walks. This work is also important for the development of quantum search algorithms which can be much faster than their classical counterparts.

Gil M. Repa from Dr. Zhou's Lab Receives Wentz Research Grant



Gil M. RepaCongratulations to Gil M. Repa, a Biochemistry major working in Dr. Zhou's Biological Physics group, on his reception of a Wentz Research Grant. Recently Gil also won the 2nd place in OSU College of Arts and Sciences Undergraduate Three Minute Thesis (3MT) Competition on February 23, 2018. In the event, undergraduates presented their own research in 3 minutes with the assistance of only one power point slide. Scholarships ranging from $1,250 to $500 were awarded to the first through fifth place finishers. The title of his presentation was Structure-based Drug Design for Cancer. His presentation can be viewed on, starting at about 33 min. On April 14, Gil presented again at an OSU Heritage Foundation Celebration fundraising event.

Dr. Donghua Zhou Receives 2018 OSU President's Fellows Faculty Research Award



Dr. Donghua Zhou received the 2018 President's Fellows Faculty Research Award to study the structure of protein mortalin in complex with cancer drug SHetA2. This study is expected to provide accurate information for structure-guided design of compounds with the best cancer inhibition power and the least toxicity. Dr. Zhou was one of the three faculty honored  at the 2018 Researcher's Reception on March 28.
