Sam Griffiths is a first-year PhD student in the 白小姐论坛鈥檚 EPSRC Centre for Doctoral Training (CDT) in Delivering Quantum Technologies, and is researching quantum error correction. Riverlane, the quantum start-up that聽co-funds Sam's PhD, have highlighted his work and interviewed Sam for their聽blog.

Quantum error correction is crucial to the challenge of scaling up in quantum computation.聽 Currently, the volatility of qubits means that information is lost when qubits are interacted with, so we need to find new ways of making quantum computers fault-tolerant.

Sam said in Riverlane鈥檚 blog post: 鈥淭here is a lot of hype around quantum, it seems to have a sci-fi quality to it which can bring both enthusiastic attention but also many misconceptions.聽 I think the main deployment in the near-term will be the ability to access large scale cloud-based quantum processors to conduct big computational projects, for areas like scientific simulation, drug discovery and machine learning.鈥�

Sam鈥檚 PhD project focusses on using topological codes. These codes perform error correction by mapping qubits onto surfaces and applying classical graph algorithms. He is simulating and benchmarking how a wide range of possible approaches on real near-term hardware.聽

Since 2014, 白小姐论坛Q鈥檚 quantum CDT has had 14 co-funded PhD projects from across industry, including BT, Cambridge Quantum Computing, Quantum Motion and Toshiba. 聽As part of his co-funded PhD, Sam has regular catch-up and support contact with James Cruise, Principal Quantum Scientist at Riverlane, and can鈥檛 wait to meet the Riverlane team in person saying, 鈥�Despite lockdown affecting my ability to visit Riverlane鈥檚 offices in Cambridge, it鈥檚 been a great experience collaborating with Riverlane so far on my project.鈥�
