Tokyo Institute of Technology
Scientists at Tokyo Institute of Technology and Keio University investigated the excitation and detection of photogenerated coherent phonons in polar semiconductor GaAs through an ultrafast dual pump-probe laser for quantum interferometry.
Imagine a world where computers can store, move, and process information at exponential speeds using what we currently term as waste vibrations—heat and noise. While this may remind us of a sci-fi movie, with the coming of the nano-age, this will very soon be reality. At the forefront of this is research in a branch of the quantum realm: quantum photonics.
