Control of Quantum Dots with Acoustics.  
Sound waves are being researched to control quantum dots. Essentially, researching an acoustic resonator which focuses acoustics at the nanoscale level is the brunt of the effort. The benefit is in the reduced disruption to the quantum state, rather, the improved coherence tie of the encoded quantum information. This may lend to overcoming one of quantum computing’s largest challenges – decoherence.
