The Ginsburg Center opens
June 18, 2026
Today Caltech held the grand opening of the Dr. Allen and Charlotte Ginsburg Center for Quantum Precision Measurement — the building we recently moved into.
It is the first building at Caltech to bring precision measurement, quantum information, and gravitational-wave detection under one roof: 70,000 square feet whose seven laboratories sit 28 feet below grade on a single three-foot-thick concrete slab, with temperature held to within a tenth of a degree and a quiet electromagnetic environment. Those are the conditions that set the noise floor for the coating thermal-noise, quantum squeezing, and precision optomechanics measurements at the heart of our work — so the building is, in effect, part of the apparatus.
Nearly all of our experimental laboratories and group offices are now here (the 40-meter prototype interferometer stays in its current home and keeps running). Photos from the opening and our new labs will follow.
