Keynotes

While industry 5.0 is in advanced stages of development in many industry segments, a number of areas are significantly lagging behind – among others for reasons of cost (or return on investment), regulatory & safety, complexity. At the same time, sustainable health, sustainable agri and sustainable food are among the biggest problems our society faces. 

The number of automobiles owned in the world exceeds 1.5 billion, and major social issues are arising as the number increases and society changes. These include increasing traffic safety issues, traffic congestion issues, environmental issues related to exhaust gas, CO2 emissions and noise, and large consumption of petroleum energy. 

I will describe recent results from my group, where we have shown that we can emit and detect individual microwave-frequency surface acoustic wave phonons on-demand. We have used these phonons to transmit quantum states and generate quantum entanglement; demonstrated a single-phonon interferometer and a quantum information process known as “quantum erasure”; and most recently demonstrated the acoustic Hong-Ou-Mandel effect with phonons, illustrating the wave-particle duality fundamental to quantum mechanics. Interestingly, this last development points to the possible development of a phonon-based architecture for quantum computing.
