Guifré Vidal is a Spanish physicist who studies the tiny world of quantum physics. He uses special math and computer tools to understand how many tiny particles work together. He is a top expert in something called tensor network states.
He helped create important methods like time-evolving block decimation (TEBD) and multiscale entanglement renormalization ansatz (MERA). These tools help scientists solve very complex problems in quantum physics. Before joining Sandbox @ Alphabet in 2019, he worked at the Perimeter Institute in Canada.

Who is Guifré Vidal?
Guifré Vidal was born in Barcelona, Spain. He became a physicist, which is a scientist who studies how the universe works. He focuses on the strange and exciting rules of quantum mechanics. This is the part of physics that looks at the smallest things, like atoms and their parts.
What is Quantum Physics?
Quantum physics explores the behavior of matter and energy at the smallest scales. It's different from the physics we see every day. For example, particles can be in many places at once! Understanding how many of these tiny particles interact is called quantum many-body physics. It's a very challenging area of science.
Understanding Tensor Networks
Guifré Vidal is famous for his work with tensor networks. Imagine you have a huge puzzle with millions of pieces. A tensor network is like a clever way to organize these pieces. It helps scientists simplify very complex quantum problems. This makes it easier to study how many quantum particles behave together.
Time-Evolving Block Decimation (TEBD)
One of the tools Guifré Vidal helped create is called time-evolving block decimation (TEBD). Think of it as a special computer program. It helps scientists understand how quantum systems change over time. It's especially useful for studying materials with many interacting particles.
Entanglement Renormalization (MERA)
Another important method he developed is multiscale entanglement renormalization ansatz (MERA). This is a way to look at quantum systems at different levels, like zooming in and out. It helps scientists understand entanglement, which is a special connection between quantum particles. MERA is very good at describing systems that have complex patterns.
His Career Journey
Guifré Vidal studied at the Universitat de Barcelona. He later worked at the Perimeter Institute in Waterloo, Canada. This institute is a leading center for theoretical physics research. Since September 2019, he has been a research scientist at Sandbox @ Alphabet. This shows his work is important for new technologies.
