Researchers have measured an optical clock's ticking with record-breaking accuracy while also showing the clock can be operated with unprecedented consistency. These achievements represent a significant step toward demonstrating that the new generation of optical atomic clocks are accurate and robust enough to be used to redefine the official length of a second, which is currently based on microwave atomic clocks.
