| Details: | Quantum computation is the 'It girl' of this generation. Very useful, very beautiful and has too many rich people pouring money on it for a chance to get its attention. But is the hype matched by current technologies? How good is modern quantum computing? How does interdisciplinarity play a huge role in its development? In this Gluon talk we will first cover some basics on the physics of quantum computation, notably touching on how spins talk to each other and how quantum circuits are made. I will describe the phenomena of 'non-thermal state-polarisation' through external stimuli and the different types of quantum computing approaches using them. Then I will move onto showing how modern architectures either work at near-0K or have no controllability, so its not yet something you can use to break into your enemies credit card and buy useless stuff with. We will together simplify the problem into a thought experiment where a specific electronic structure can yield remarkable results. We will then slowly move away from atomic or inorganic semiconductors and into the dark arts of highly controlled and repeatable organic chemistry. This will help tailor such an electronic structure in a molecule. This is where materials science kicks in. In the end I will show how, in a paper I are hopeful about, I use this to achieve a fully organic qubit for the first time in history. I have a simple objective-To show to physicists how simplifying problems can help chemists design the perfect material and, to show chemists how we can take a page from physics and make molecular semiconductors that modern technologies need. We must work together at this intersection to achieve great things! |
