Fully Funded EPSRC DTP PhD Scholarship: Towards Organic Quantum Memristors

Overview

Description

This fully funded project will explore the application of organic semiconductors in quantum computing. Building on research into organic memristors for neuromorphic computing, we are looking to exploit quantum phenomena in these devices and to ultimately realise an organic quantum memristor (QM).   

Memristors themselves are promising devices for realising multi-state memory, physical neural networks and neuromorphic computing [1]. Recently, we have developed high quality organic memristors that emulate the synaptic behaviour of the brain using squaraine molecules, first using self-assembled nanowires before moving to thin-film devices that are can be integrated with current semiconductor processes [2]. 

A QM is a device that couples classical memristive behaviour with quantum coherence [3]. Several approaches to realise QMs have been envisaged and more recently a quantum optical memristor has been demonstrated experimentally [4-7]. Quantum coherent states can be realised in certain organic semiconductors through the coupling of photons and excitons to form an exciton polariton [8,9].  

In this project, the application of organic exciton polaritons in memristors will be explored to first understand how they can be exploited in optoelectronic memristors before using them to devise a true organic quantum memristor.
