Fermilab-MIT team hits cryoelectronics milestone for scalable quantum computing

Researchers at Fermi National Accelerator Laboratory and the Massachusetts Institute of Technology’s Lincoln Laboratory have successfully trapped and manipulated ions using in-vacuum cryoelectronics, allowing for reduced thermal noise and improved sensitivity. This proof-of-principle experiment marks an important advancement toward building large-scale ion-trap quantum computing systems. At the heart of the effort were Fermilab-developed cryoelectronics – specialized circuits designed to operate at the extreme cold temperatures required for quantum computers. These cryoelectronics were integrated into MIT Lincoln Laboratory’s ion-trap platform to test whether they could reliably perform key functions: moving individual ions, holding them at set positions and measuring the effects of electronic noise. Rigetti Computing (RGTI) is partnered with Fermilab to build quantum computer.
