PhD in Engineering - Ultrafast Quantum Nanoelectronics with THz pulses

Quantum technology has been on the spotlight of UK’s research and innovation for the last few years. The ‘holy grail’ of all these efforts is to create the first ‘Quantum Computer’, which unlike our regular, ‘classical’ computers can perform operations exponentially faster and with higher accuracy. The fundamental building block of all quantum technologies, called the ‘Qubit’, is still under investigation and there are currently many technologies that can create reliable qubits that can be easily manipulated, ranging from flying, superconducting, quantum dots etc.

Creating a handful of qubits is a relatively easy task nowadays, however, the major problem of most quantum technologies is their scalability and robustness, meaning to put together thousands of qubits on the same device. The robustness aspect is a critical problem that has to be addressed quickly, as qubits are proned to errors from their surrounding environment and therefore jeopardize the accuracy of the quantum calculations.

In this PhD project we will investigate the potential of using THz optoelectronics to create ultrafast voltage pulses and use them to create robust qubits. We will develop THz sources that will deliver very short electrical pulses in a solid-state quantum system. These pulses will be then converted into flying electrical qubits that can be measured and manipulated at cryogenic temperatures.

The PhD candidate will work on the development of the THz optoelectronics for creating ultrafast electrical signals and their integration with the solid-state quantum systems. The PhD candidate will be involved in advanced nanofabrication in our state-of-the-art James Watt Nanofabrication Centre (JWNC), perform simulations of the devices and experimentally characterize the devices at room temperature and cryogenic temperatures. 

The project will require both individual and group work in collaborative environments and the successful candidate should be capable of working in both environments. Experience with computer programming (C or C++ or Python or Matlab etc), simulations (Comsol or Lumerical or HFSS) or data acquisition and analysis is not essential but it is advantageous. 

Through this project, we will provide to the successful candidate a top-quality PhD-level training in Quantum Engineering and advanced Nanofabrication. In addition, the candidate will benefit from funding that will cover tuition fees and stipend for up to 3.5 years (funding is only available for students based in the UK).
