QML Scientist

Cambridge Quantum Computing has a vacancy for a QML Scientist to join its Machine Learning and Quantum Algorithms team

  • Closing date: 16 Dec 2020
  • United Kingdom | Cambridge Quantum Computing
  • Date posted: 16 Nov 2020
  • Job type: Industry & business
  • Disciplines: Quantum science & technology  | Computational science & software engineering 

Cambridge Quantum Computing (CQC), is dedicated to developing and deploying advanced scientific research to lead us into the quantum age. CQC’s mission is to develop the world’s best quantum-based products and to make meaningful impacts on humanity.

Quantum machine learning (QML) is one of the most interesting applications of quantum computers. For example, parameterized quantum circuits (PQC) can be trained to perform tasks such as classification, regression, and generative modelling (see our recent Topical Review [1] for an introduction).

QML algorithms can be successfully implemented using hybrid quantum-classical systems and are amongst the most promising techniques to show a near-term impact on real-world problems. Firstly, it has been empirically shown that they can cope with noise, a limited number of quantum bits, and shallow circuits. Secondly, it has been theoretically shown that some classes of circuits have remarkable expressive power and share many aspects with classical neural network models. Also, QML borrows many concepts with Deep Learning and other areas of statistical learning and these links have not been thoroughly explored; in this respect, it offers great opportunities to Machine Learning experts interested in quantum computing applications.

The field is thriving with new ideas and open questions such as proving quantum advantage, assessing computational complexity, designing variational circuits, and efficient state preparation, to name a few.

CQC is looking to expand its cutting-edge Machine Learning and Quantum Algorithms team with a full-time research lead. The role entails contributing to world-class scientific research on quantum algorithms for supervized [2] and unsupervized [3] learning. We are also looking to expand our research portfolio in directions that can demonstrate the impact of PQC on computational techniques with business applications. The research will be both theoretical and aimed at prototyping and benchmarking new algorithms on the state-of-the-art of quantum computers.

This position is embedded in a team of world-class academics focusing on hybrid quantum algorithms for near term application, such as combinatorial optimization and Monte Carlo sampling, in partnership with some of the global leaders in the financial, manufacturing, chemical and shipping industries.

Key requirements

  • PhD in quantum physics, computer science.
  • Knowledge of quantum information, quantum algorithms and machine learning.
  • Published research in at least one relevant topic.

Desirable skills

  • Peer-reviewed publications on high impact factor journals.
  • Familiarity with NISQ device and their implementation aspects.
