An almost dissipation-free quantum clock. The idea for this new kind of clock came out of a meeting at the Quantum Thermodynamics Conference in Vienna in 2023.

For now, this technical skirting of the Second Law of Thermodynamics is only theoretical. However, the authors note that this idea could be tested using modern superconducting circuits. If the ...

Reading a quantum clock is not like reading a classical one. The act of using it to determine the time would trigger a counterintuitive quantum phenomenon: measurement disturbance.

Like second and minute clock hands "So we have a fast process that does not cause entropy—quantum transport—and a slow one, namely the arrival of the particle at the very end," explains Yuri ...

As tiny imperfections in the clock cause the laser to drift from the ideal frequency, a device called an interferometer tracks this deviation so that the clock can get back on track. The quantum ...

The Quantum Clock Is Ticking. With quantum computing only a few years away, quantum security is already a priority for trailblazing organizations working on developing and standardizing PQC and ...

This is known as quantum entanglement, and the new clock takes advantage of that phenomenon for higher precision timekeeping. The researchers started with about 350 atoms of ytterbium-171, which ...

The quantum clock, developed by physicist Chin-wen Chou of the NIST, keeps time by measuring the energy of a single aluminum ion with UV lasers. It loses one second every 3.4 billion years, ...

Quantum mechanics may seem like an abstract theory far removed from everyday experience, but in fact it's essential to something as mundane as an alarm clock.

The clock is ticking toward a time when quantum computers will be able to hack today's most common and sophisticated security systems. The clock has a name, the Y2Q clock, ...
