Fermionic quantum computer

Fermionic quantum computer

Fermionic quantum computer: By loading ultracold Sr atoms in highly controllable optical potentials, we aim to build a fermionic quantum simulator and computer for chemistry. Also, using two electronic states of Sr, we can realize a qubit based computer.

New states of matter

New states of matter

New states of matter: By simulating paradigmatic Hamiltonians and Liouvillians, we will realize new dynamics and states of strongly correlated topological matter.

My very first nanophotonic waveguide... well, almost... photoresists still needs to be removed :P ... a new exciting project is in full steam ;)

California Institute for Quantum Emulation

CAIQuE brings together researchers from five UC campuses with a joint focus on driving advances in research, education, and training in the fast growing field of quantum emulation.
The Barreiro Lab is building two ultracold Strontium experiments aimed at (i) creating new states of matter and realizing a (fermionic) quantum computer and (ii) realizing quantum sensors for fundamental physics and applications.
Our work has been sponsored by grants from the Regents of the University of California, the Sloan Foundation and DARPA.
