Next-generation atomic timekeeping techniques could push new frontiers in quantum physics, according to a new study. Atomic clocks are essential elements in GPS and other navigation systems — and a ...
The following is an extract from our Lost in Space-Time newsletter. Each month, we hand over the keyboard to a physicist or two to tell you about fascinating ideas from their corner of the universe.
Scientists built a tiny clock from single-electron jumps to probe the true energy cost of quantum timekeeping. They discovered that reading the clock’s output requires vastly more energy than the ...
Quantum technologies—devices that operate according to quantum mechanical principles—promise to bring users some groundbreaking innovations in whichever context they appear. Ironically, the same ...
The steady tick of a clock usually feels simple and dependable. Something swings or vibrates in a controlled rhythm and marks the passing of each moment. What you rarely notice is the hidden cost ...
Breakthrough trial with Tiqker clock aboard XCal submarine advances resilient navigation in GPS-denied environments Testbed submarine XV Excalibur went to sea with Infleqtion’s quantum optical atomic ...
Why have just one technological breakthrough when you can have two at the same time? The Royal Navy has installed for the first time a quantum clock into its XV Excalibur robotic submarine for ...
Physicists at the University of Oxford have successfully linked two atomic clocks through quantum entanglement for the first time. The feat can help make these clocks so precise that they begin to ...
The reconciliation of general relativity and quantum mechanics is one of the biggest challenges in science, one that continues to elude us. Now, a new study by Anjun Chu and colleagues has examined ...
Graphic illustrating the difference in energy between running a quantum clock (left: a single electron hopping between two nanoscale regions) and reading the ticks of the clock (right). The energy ...
