Users/Collaborations

In the last decade, DQC scientists pioneered the simulation of semi-tunable quantum Hamiltonian models based on trapped atomic ions as interacting spins; much this research will appear in an upcoming Review of Modern Physics article. 

In 2015, we designed and built the first fully-connected and reconfigurable universal quantum computer. This device competed favorably with behemoth industry quantum computer systems offered on the cloud—but we were just getting started.

In 2017 we designed and built the world’s most powerful quantum computer, with up to 32 fully-connected qubits and better then 99 percent fidelity on gates. This system was unleashed in 2019, has been running remotely and semi-autonomously since February 2020, and we are now operating and building two next-generation systems.

Along the way, our team has formed a large number of collaborations with researchers worldwide, who generally come to us with a research problem in their own field—from condensed-matter and nuclear physics to cosmology and game theory. Below we list the collaborations, many of which produced new science in the form of a publication.
