The US military has invested in quantum research to explore how vibrations influence the electronic behavior of ultrathin materials.
Scientists at the University of California, Riverside, are studying whether these vibronic effects could eventually 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 between biological and synthetic systems.
Vibrations become a mechanism for controlling quantum behavior
Unlike conventional computing which relies on binary states, quantum approaches exploit phenomena such as superposition, where a wave function exists in multiple locations simultaneously.
QuVET researchers want to determine whether a quantum wavefunction crosses an interface or stays where it originally resides.
“The idea is that vibrations could become the control button, 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 key to improving technologies such as solar power generation, where light creates neutral excitations that must separate into free charges.
If this energy is not extracted quickly enough, it dissipates as heat or is re-emitted as light instead of becoming usable electricity.
Gabor noted that biological systems have evolved methods to extract energy extremely quickly, and his team aims to replicate this efficiency in artificial materials.
During photosynthesis, a charge-neutral quantum excitation moves from molecule to molecule until it reaches a reaction center, where separation occurs.
The same physics that allows plants to harvest sunlight could eventually enable new forms of quantum control and computation in synthetic layered devices.
Army sees strategic value in quantum control research
The U.S. Army funded this quantum research through a Multidisciplinary Academic Research Initiative grant administered by its Combat Capabilities Development Command Army Research Office.
Tania Paskova, a program manager in that office, said understanding vibronic effects could prove instrumental for future artificial biological systems designed by military scientists.
“This research answers crucial scientific questions that could be instrumental in understanding and controlling vibronic effects in artificial biological systems,” she said.
“By establishing roadmaps for using vibronic effects for novel quantum photonic and optoelectronic devices, this research has the potential to significantly advance the Army’s future capabilities in quantum computing, secure communications, and sensing technologies.”
The Army recognizes, however, that significant obstacles remain before any practical military application emerges from these laboratory results.
Most quantum experiments require cryogenic temperatures and highly controlled conditions that do not easily apply to battlefield environments.
By funding basic research rather than requiring immediate prototypes, the military is making a long-term strategic bet on physics that could take decades to mature.
Whether this investment results in real advances in quantum computing or just interesting scientific notes depends entirely on experimental results that don’t yet exist.
