Among California\u2019s seven contributions<\/a> to the time capsule, Newsom selected several items reflecting the state\u2019s innovation economy, including the quantum chip and a segment of a conductor fabricated in San Diego for an experimental nuclear fusion reactor.<\/p>\n \u201cThese items represent the innovative technology California leads the nation and globe in, capturing the remarkable spirit and communities that make the Golden State one-of-a-kind,\u201d the governor\u2019s office wrote in a June 15 announcement.<\/p>\n Also included in the time capsule were a letter to future Californians from the governor and his partner, and a prediction of the state\u2019s future generated by Anthropic\u2019s AI agent, Claude.<\/p>\n Rich Press\/NIST<\/p>\n The 10 millimeter-square chip is the first widely distributed quantum processing unit, or QPU. Produced in collaboration with Berkeley Lab in a project led by Berkeley physics Professor Iran Siddiqi, the chip consists of eight qubits \u2014 quantum bits that are the fundamental unit of information in a quantum computer, analogous to the binary bits of a digital computer.<\/p>\n Scientists hope that quantum computers will one day solve problems that are computationally challenging or impossible for classical digital computers. Through Berkeley Lab\u2019s Advanced Quantum Testbed, Berkeley\u2019s eight-qubit QPU has been used by many groups around the world to test new kinds of quantum computations, such as simulating neutrino interactions and the internal structure of nuclei.<\/p>\n \u201cIt was designed at UC Berkeley, fabricated at UC Berkeley and provided to the scientific community by Berkeley Lab, so it reminds you of the ecosystem we have in California,\u201d said Kan-Heng Lee, a research scientist at Berkeley Lab who oversaw production of the chip.<\/p>\n Lee said that the chip was fabricated first in the Marvel NanoLab<\/a> in Sutardja Dai Hall and finished in the Quantum Nanoelectronics Lab<\/a> in Campbell Hall. When in use, chips like this are cooled to a few thousandths of a degree above absolute zero. At this temperature, the circuit is superconducting and the thermal noise that would interrupt the quantum circuits is substantially reduced.<\/p>\n![\"shiny](\"https:\/\/www.newsbeep.com\/us-ca\/wp-content\/uploads\/2026\/06\/NIST-A250-Time-Capsule-001-scaled-crop-656x1024.jpg\")
The America250 time capsule will be buried July 4, 2026, in Philadelphia and opened on July 4, 2276, America\u2019s 500th birthday, or quincentennial. The stainless steel cylinder is shown in the machine shop were it was made at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland.<\/p>\n
