Quantum Machine Learning Scientist

Research at Cambridge Quantum Computing

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 this links have not been thoroughly explored; in this respects, 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.

Role description

Cambridge Quantum Computing ltd (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 supervised [2] and unsupervised [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.

Fundamental 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 experience

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