Copper damascene process brings electronics and photonics together

— EPFL researchers have, for the first time, applied the semiconductor industry’s standard copper wiring process to ferroelectric thin film photonics. By building lithium tantalate modulators with copper instead of gold, they remove a major barrier to 3D integration with advanced CMOS electronics and move optical interconnects closer to large scale deployment in data centers and AI clusters.

“I thrive in environments where the rules aren't fixed”

— Quantum computing is often sold as a magic bullet that will quickly solve today’s intractable problems. Yihui Quek prefers to balance this optimism with scientific rigor, and instead ask the question: what do we want a quantum computer to be good for?
