Our Quantum Reality: A Physics-Art Project

Posted on April 1, 2019 by P A Knott

Cross posted from FQXi’s blog: https://fqxi.org/community/forum/topic/3253 I recently completed a collaborative art-physics project, with award-winning artist Joseph Namara Hollis, to produce a short, illustrated book about the quantum mechanical reality in which we live. From the start, this was an ambitious … Continue reading →

Why the many worlds interpretation of quantum mechanics is fantastic

Posted on May 18, 2018 by P A Knott

Why many worlds? Quantum mechanics is often presented as being “our most successful theory ever”. Despite 100 years of stringent experimental tests it has never been proved wrong. It has been confirmed to an accuracy of 1 part in 1012 … Continue reading →

Computers designing quantum optics experiments

Posted on April 14, 2017 by P A Knott

Quantum states can exhibit bizarre but powerful properties, such as being in a superposition or containing correlations not possible in classical physics. If these properties can be controlled, then they can be exploited in quantum technologies to dramatically transform computing, enable … Continue reading →
