About P A Knott

I currently hold a Research Fellowship from the Royal Commission for the Exhibition of 1851. My research project will tackle a key challenge in the quantum technology revolution by designing computer algorithms that automate the engineering of useful quantum states. These algorithms will enable the design of novel experiments to bring forward the development of new technologies such as quantum computing, communications and metrology. In my previous post I worked at the University of Nottingham on a project entitled "Sentient observers in the quantum regime and the emergence of objective reality", with Gerardo Adesso, Marco Piani, and Tommaso Tufarelli. This project involved using quantum information theory to investigate foundational questions concerning the role of the observer in physical theories. More generally, my research interests include quantum metrology, quantum state engineering, quantum sensing networks, and optical interferometry.

Using a genetic algorithm to design quantum experiments

How can we design experiments in quantum physics? Generally, the strategy involves using the vast knowledge amassed by quantum physics researchers and combining this with our intuitions and our creativity. This method has been fantastically successful over the years and … Continue reading

Will artificial intelligence take over the world?

In recent years, there has been increasing concern that sometime in the future a super-intelligent AI will rise up, take over the world, and destroy all humanity. Is this a real concern? Or is it over-hyped science fiction, with no … Continue reading

Why the many worlds interpretation of quantum mechanics is fantastic

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

What does quantum mechanics tell us about reality? Part II

This blog post follows on from a previous post, “What does quantum mechanics tell us about reality”, in which I tried to give a balanced and non-technical overview of some of the interpretations of quantum mechanics. In this post I will … Continue reading

What does quantum mechanics tell us about reality?

In this blog post I will introduce a core philosophical issue at the heart of quantum mechanics, and some of the most popular resolutions to this problem. This will be a non-technical introduction – I will try to avoid jargon … Continue reading

Computers designing quantum optics experiments

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
