Sound Waves Enter the Quantum Arena: University of Chicago Pioneers Phononic Quantum Computing

A weird and wonderful array of technologies are competing to become the standard-bearer for quantum computing. The latest contender wants to encode quantum information in sound waves.

One thing all quantum computers have in common is the fact that they manipulate information encoded in quantum states. But that’s where the similarities end because those quantum states can be induced in everything from superconducting circuits to trapped ions, ultra-cooled atoms, photons, and even silicon chips.

While some of these approaches have attracted more investment than others, we’re still a long way from the industry settling on a common platform. And in the world of academic research, experimentation still abounds.

Now, a team from the University of Chicago has taken crucial first steps towards building a quantum computer that can encode information in phonons, the fundamental quantum units that make up sound waves, in much the same way that photons make up light beams.

The basic principles of how you could create a “phononic” quantum computer are fairly similar to those used in “photonic” quantum computers. Both involve generating and detecting individual particles or quasiparticles and manipulating them using beamsplitters and phase shifters. Phonons are quasiparticles because although they act like particles as far as quantum mechanics are concerned, they are actually made up of the collective behavior of large numbers of atoms.

Scientists open door to manipulating ‘quantum light’

Photonic bound states could advance medical imaging and quantum computing

For the first time, scientists at the University of Sydney and the University of Basel in Switzerland have demonstrated the ability to manipulate and identify small numbers of interacting photons — packets of light energy — with high correlation. advertisement This unprecedented achievement represents an important landmark in the development of quantum technologies.

It is published today in Nature Physics. Stimulated light emission, postulated by Einstein in 1916, is widely observed for large numbers of photons and laid the basis for the invention of the laser. With this research, stimulated emission has now been observed for single photons. Specifically, the scientists could measure the direct time delay between one photon and a pair of bound photons scattering off a single quantum dot, a type of artificially created atom.

“This opens the door to the manipulation of what we can call ‘quantum light’,” Dr Sahand Mahmoodian from the University of Sydney School of Physics and joint lead author of the research said.
