Summary

Story summary

Intel CEO Lip-Bu Tan said quantum computers will operate alongside CPUs and GPUs.
Intel Labs unveiled the Tunnel Falls silicon spin-qubit chip and the Horse Ridge II cryogenic controller.
Tan warned that cryogenic infrastructure will restrict quantum scaling for three to five years.
President Donald Trump signed June executive orders to strengthen U.S. quantum supply chain, develop sensing, and set a scientific-grade roadmap.

History

Historical Context

IBM demonstrated NMR quantum logic in 2001, and the U.S. enacted the National Quantum Initiative Act in 2018 to coordinate federal-industry research. Building on that framework, Intel released the Tunnel Falls spin-qubit chip and the Horse Ridge II cryogenic controller, enabling testing of a 12-qubit silicon processor on a 300-mm wafer. These steps extend early quantum-logic experiments toward scalable hardware.
