Building on this achievement, Devoret, Martinis, and many others are constructing quantum computers, powerful tools for exploring quantum science and solving very hard computational problems. Congratulations!

We’re excited to propose and validate simple methods for preparing ground states and thermal states of many-particle quantum systems, which might be feasible for early fault-tolerant quantum devices. All the credit goes to my brilliant collaborators Zhiyan, Yongtao, and Lin

End-to-End Efficient Quantum Thermal and Ground State Preparation Made Simple
We propose new quantum algorithms for thermal and ground state preparation based on system-bath interactions. These algorithms require only forward evolution under a system-bath Hamiltonian in which t...

Yiyi Cai has done research in our group @caltech.edu for two years, including a senior thesis. She'll be a Gates Cambridge Scholar for a year, followed by PhD studies in computer science at Stanford. Congratulations, Yiyi, you'll be missed!

The building committee gets a first look at the basement of the Ginsburg Center for Quantum Precision Measurement at Caltech. We're standing where a tunnel will connect Ginsburg labs to labs in neighboring Downs Laboratory. With me are Nick Hutzler, Rana Adhikari, Michelle Effros, and Dave Hsieh.

After a long hiatus, we are finally getting around to posting our coolest undertaking during the conference--interviews with some of the biggest names in our field about the early days of QIP!

First in our lineup is our interview with the one and only John Preskill (@preskill.bsky.social)! (1/4)
