Guifré Vidal is a Spanish physicist. He studies how many tiny particles, like atoms, act together. This field is called quantum many-body physics. He uses special math and computer methods to understand these complex systems.
Dr. Vidal is a top expert in tools called "tensor network states." These tools help scientists solve very difficult problems in quantum physics. Two important methods he works with are time-evolving block decimation (TEBD) and multiscale entanglement renormalization ansatz (MERA).
He used to be a professor at the Perimeter Institute in Waterloo, Canada. In September 2019, he became a research scientist at Sandbox @ Alphabet.

Who is Guifré Vidal?
Guifré Vidal is a scientist who explores the amazing world of quantum physics. He tries to understand how the smallest parts of our universe behave. His work helps us learn more about materials and new technologies.
Early Life and Education
Guifré Vidal was born in Barcelona, a big city in Spain. He went to the Universitat de Barcelona for his university studies. There, he earned his advanced degree, called a doctorate. His main teacher for this was Rolf Tarrach.
Later, he also learned from other famous scientists. These included Ignacio Cirac and John Preskill. They are well-known for their work in quantum physics.
What He Studies
Dr. Vidal focuses on a part of physics called quantum many-body physics. This area looks at what happens when many tiny particles interact with each other. Imagine trying to understand how millions of tiny magnets all pull and push on each other at the same time! It's very complicated.
Understanding Tiny Particles
In the quantum world, particles don't always act like everyday objects. They can be in many places at once or be connected in strange ways. Scientists like Dr. Vidal use special math to describe these behaviors. This helps them predict how new materials might work or how to build new types of computers.
Using Tensor Networks
To solve these complex problems, Dr. Vidal uses powerful tools called "tensor networks." Think of a tensor network as a special kind of map. This map helps scientists organize huge amounts of information about many particles.
Two important tensor network methods he helped develop are:
- Time-Evolving Block Decimation (TEBD): This method helps scientists understand how quantum systems change over time. It's like making a movie of tiny particles interacting.
- Multiscale Entanglement Renormalization Ansatz (MERA): This method helps simplify very complex quantum systems. It's like zooming out to see the big picture, while still understanding the important details.
These tools are very useful for studying materials and for developing quantum computers.
Where He Has Worked
Dr. Vidal has worked at important research centers around the world. He was a faculty member at the Perimeter Institute in Waterloo, Canada. This institute is famous for its research in theoretical physics.
In September 2019, Dr. Vidal moved to a new role. He became a research scientist at Sandbox @ Alphabet. This is a company that works on advanced scientific projects.
