Overview
My academic research group  works in the following areas:
  • Quantum information theory, quantum algorithms and computation.
  • Quantum resource theories (entanglement, coherence, asymmetry, thermodynamics, etc.).
  • QI in many-body and quantum field theories.
Recent times

  • 14/07/21 Welcome to Cristiano Duarte, who has joined the group on an EPSRC grant!
  • 30/06/21 New work with Nick Koukoulekidis (Imperial College) on magic state distillation bounds for quantum computing via majorization theory.
  • 01/05/21 Congrats to new PhD student Si Chen, who was awarded a prestigious Bell-Burnell Scholarship (Press-release).
  • 12/04/21 New work with Matt Girling (Leeds), and Cristina Cirstoiu (CQC) on randomized benchmarking and non-separability in quantum channels.
  • 25/12/20 Postdoc position in Quantum Technologies is now available in our group, closing date 3rd Jan 2021.  [Now closed]
  • 18/12/20 Work with Cristina Cirstoiu (CQC) and Kamil Korzekwa (Jagiellonian University) on the extension of Noether's principle to quantum channels is now published in Phys. Rev. X   [link to paper].​​
