The US Army has invested in quantum research that examines how vibrations affect electronic behavior in ultra-thin materials.
Researchers at the University of California, Riverside, are investigating whether these vibrational effects could ultimately transform both energy harvesting and computing systems.
The Center for Quantum Vibronics in Energy and Time (QuVET) brings together physicists, chemists, engineers and biochemists to study these fundamental interactions across biological and synthetic systems.
Vibrations become a control mechanism for quantum behavior
Unlike conventional computing that relies on binary states, quantum approaches take advantage of phenomena like superposition, where a wave function exists in multiple places simultaneously.
QuVET researchers want to determine whether a quantum wave function jumps across an interface or stays where it originally is.
“The idea is that vibrations can become the control knob, enabling future ‘quantum vibronic switches’ that use crystal vibrations to turn quantum transitions on and off,” said Nathaniel Gabor, professor of physics and astronomy.
Understanding this switching process is critical to improving technologies such as solar energy generation, where light creates neutral excitations that must be separated into free charges.
If that energy is not extracted quickly enough, it disappears as heat or is re-emitted as light instead of becoming usable electricity.
Gabor noted that biological systems have developed methods to extract energy extremely quickly, and his team aims to replicate this efficiency in artificial materials.
In photosynthesis, a charge-neutral quantum excitation travels from molecule to molecule until it reaches a reaction center where dissociation occurs.
The same physics that enable plants to harvest sunlight could eventually enable new forms of quantum control and computation in synthetic layered devices.
The Army sees strategic value in quantum control research
The U.S. Army has funded this quantum research through a multidisciplinary university research initiative managed by its Command’s Army Combat Capabilities Development Office of Research.
Tania Paskova, a program manager in this office, stated that the understanding of vibronic effects could prove instrumental in future artificial biological systems designed by military scientists.
“This research answers critical scientific questions that may be instrumental in understanding and controlling vibrational effects in artificial biological systems,” she said.
“By establishing roadmaps for using vibronic effects for new quantum photonic and optoelectronic devices, this research has the potential to significantly advance future Army capabilities in quantum computing, secure communications and sensing technologies.”
However, the Army acknowledges that significant hurdles remain before any practical military application comes out of these lab results.
Most quantum experiments require cryogenic temperatures and highly controlled conditions that do not easily translate to battlefield environments.
By funding basic research rather than requiring immediate prototypes, the Army is making a long-term strategic investment in physics that can take decades to mature.
Whether this investment yields genuine quantum computing advances or merely interesting scientific footnotes depends entirely on experimental results that do not yet exist.
