The discovery may lead to a new method of quantum computing.
"It provides a new type of involved quantum effect that can be utilized to control single photons running through integrated optical circuits for many applications."
The new study builds on previous work that examined a quantum-level quasiparticle called an "exciton." Information can be encoded into an exciton and then released in the form of a photon whose quantum properties can function as a quantum bit of information, or "qubit," at the speed of light.
Next, the researchers decided to test if they could harness phonons for quantum technology using electrical voltage. They found that they could vary the interaction energy of the associated phonons in measurable and controllable ways and in one single integrated system. Next the team wanted to be able to control multiple emitters and their associated phonon states, a step toward building a solid base for quantum circuitry.
"Our overarching goal is to create an integrated system with quantum emitters that can use single photons running through optical circuits and the newly discovered phonons to do quantum computing and quantum sensing," Li said"This advance certainly will contribute to that effort, and it helps to further develop quantum computing which, in the future, will have many applications.
