Researchers at NIST have developed a new quantum logic clock that achieves unprecedented accuracy, measuring time to the 19th decimal place. This advancement, built upon 20 years of development, utilizes a unique pairing of aluminum and magnesium ions, where the magnesium ion helps cool and probe the aluminum ion. The clock's enhanced stability and accuracy represent a significant step towards redefining the second with greater precision, potentially enabling new scientific and technological breakthroughs. AI
