Researchers have demonstrated a solid-state surface acoustic wave phonon laser on a tiny chip, creating coherent GHz vibrations by stacking lithium niobate and indium gallium arsenide. This chip-level device amplifies surface waves without needing an external RF source, potentially enabling all-in-one-chip signal processing for wireless communications and reducing power and size in future smartphones.
Researchers at the University of Rochester have developed a chip-scale optical quantum simulation system that could enable computers to simulate complex natural phenomena at the quantum level. By controlling the frequency of quantum entangled photons, the team created a synthetic space that mimics the physical world, allowing for more intricate simulations. This approach reduces the physical footprint and resource requirements compared to traditional photonics-based computing methods. The researchers believe this system can serve as a basis for scaling up to more complex simulations and computation tasks in the future.
