The International Race for a Quantum Computer

Silicon transistors, the essential building block of most modern electronic devices, cannot shrink much further without being rendered inoperable by quantum mechanics. This classical-quantum threshold in fact presents a tremendous opportunity: if we harness quantum mechanics, rather than attempt to avoid it, we could build a quantum computer. Quantum computers will open up a world of opportunities — they could accomplish certain computational tasks exponentially faster which would otherwise be forever impractical. A few recent demonstrations in the US and China have claimed to have already outperformed the world’s top supercomputers using quantum computers at a few specific computational challenges. During this lecture, Dr. Simmons will discuss quantum computing approaches (including her own, based upon CMOS-compatible silicon photonics), how quantum technologies will change our lives in a very fundamental way, and provide a snapshot of the accelerating worldwide race to build a prototype.
