Lightwave electronics for quantum precision

Lightwave electronics (LWE) [1,2] is set to revolutionize classical and quantum information processing by utilizing the exceptional speed of nature’s fastest processes, impacting all quantum applications beyond just quantum computing. This talk highlights several theory–experiment breakthroughs: the introduction of a quasiparticle collider [3], developments in attoclocked multi-electron quantum information [4], the ultrafast flipping of quantum states within a few femtoseconds [5], and the exploration of quantum phase transitions [6] in quantum materials. Additionally, I will discuss how LWE enhances the precision of both quantum-field and quantum-state [7] detection.
