Guifré Vidal


  • Fellow
  • Quantum Information Science




Guifré Vidal is a physicist whose research focuses on developing efficient methods, known as tensor networks, to simulate quantum many-body systems on a classical computer.

His tensor network proposals include the multi-scale entanglement renormalization ansatz (MERA).

MERA uses concepts and tools from quantum information and computation (such as quantum entanglement and quantum circuits) to implement a modern version of Wilson’s renormalization group flow on quantum spin chains. Originally developed to study quantum critical systems, over the years MERA has also found applications on a broader range of disciplines, from statistical mechanics to error correction, from quantum chemistry to applied mathematics, from quantum gravity and holography to machine learning.
