The US military has invested in quantum research exploring how vibrations influence electronic behavior in ultrathin materials.
Scientists at the University of California, Riverside, are examining 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 control mechanism for quantum behavior
Unlike conventional computing that 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 jumps across an interface or stays where it originally resides.
“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 essential to improving technologies such as solar power generation, where light creates neutral excitations that must be separated into free charges.
If that energy is not extracted quickly enough, it is dissipated as heat or re-emitted as light instead of being converted into usable electricity.
Gabor noted that biological systems have developed methods to extract energy extremely quickly, and his team aims to replicate that efficiency in artificial materials.
In 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 harness sunlight could eventually enable new forms of quantum computing and control in synthetic layer devices.
Army sees strategic value in quantum control research
The U.S. Army has funded this quantum research through a Multidisciplinary University Research Initiative grant administered by its Combat Capabilities Development Command Army Research Office.
Tania Paskova, program director at that office, said understanding vibronic effects could be critical for future artificial biological systems designed by military scientists.
“This research answers critical scientific questions that could prove critical to understanding and controlling vibronic effects in artificial biological systems,” he said.
“By establishing roadmaps for the use of vibronic effects in new 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 hurdles remain before any practical military applications emerge from these laboratory findings.
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 bet on physics that could take decades to mature.
Whether this investment will produce genuine advances in quantum computing or just interesting scientific notes depends entirely on experimental results that do not yet exist.
