Hi,

Here's a recent article regarding interaction between light and hypersound in photonic nanowires (recently published in Nature Photonics, haven't read it yet). Maybe it'll interest you, though it does not focus on quantum computing,

Hello,

Yes. There is recent work on developing a quantum memory for light in bulk diamond. A photon is stored in the optical phonon level of the diamond crystal. It's not directly quantum information processing, but certainly directed towards computing and communication. Here's the link to the article:

Hi, you guys upstairs,

Is it a good question? Yes! Optomechanical systems are now doing such a thing! The big problem for the classical computer now is the "thermal effect" for GHz-band-signal information processing. Now, the scientists can overcome this problem by converting the GHz signal into the optical band mediated by a mechanical oscillator. After an easy and “cold” signal processing in optical band, the results can be converted back by optomechanical effect for an output. You can see the physical idea in the paper:

and one application in

Yes , using photons there is a way of storing and manipulation of data through the use of photonics causing interference in electron spins and thus the manipulation in terms of state changes . 

From the base of Information Science I understand your question.

From base of Theoretical Physics is to say that light and sound have only one thing equal: they are waves. 

But sound is carried by waves swinging in air (16 Hz to 1 GHz) and light is carried by photons  (quant mechanically particles).

So it's better to combine them for Human Information transport (hear and see) but I recommend to keep sound and light in different areas. You only can mix them for bringing sound and light to a human being but not in physically way.
