An atomic clock that uses an aluminum atom to apply the logic of computers to the peculiarities of the quantum world now rivals the world's most accurate clock, based on a single mercury atom. Both ...

Digital clock projects have been with us since the 1970s, when affordable LEDs and integrated circuits became available. In 2026 most of them use a microcontroller, but for the AliExpress fans there’s ...

BOULDER, Colo.—Physicists at the National Institute of Standards and Technology (NIST) have built an enhanced version of an experimental atomic clock based on a single aluminum atom that is now the ...

Move over, mercury. Physicists at the National Institute of Standards and Technology (NIST) have built an enhanced version of an experimental atomic clock based on a single aluminum atom, making it ...

The quantum logic clock—perhaps best known for showing you age faster if you stand on a stool—has climbed back to the leading performance echelons of the world's experimental atomic clocks. Physicists ...

[Tim] noticed recently that a large number of projects recreating discrete logic tend to do so with technology around 70 years old like resistor-transistor logic (RTL) or diode-transistor logic (DTL).

Designing high-speed digital systems on FPGA platforms has always been challenging. The large amounts of routing required by SRAM-based FPGAs often limits system performance to well below that ...

Recently, scientists have built a clock that is more precise than any existing international clock. The clock is 100,000 times more precise and is called the quantum atomic logic clock. A physicist ...
