Quantum stopwatch stores time in a quantum memory

Physicists have developed a "quantum stopwatch"—a method that stores time (in the form of states of quantum clocks) in a quantum memory. In doing so, the method avoids the accumulation of errors that usually occurs when ...

Research team saves information on a single molecule

Over the past few years, the building blocks of storage media have become ever smaller. But further miniaturization of the current technology is hindered by fundamental limits of quantum mechanics. A new approach consists ...

'Blurred times' in a quantum world

When measuring time, we normally assume that clocks do not affect space and time, and that time can be measured with infinite accuracy at nearby points in space. However, combining quantum mechanics and Einstein's theory ...

Nanoscale cavity strongly links quantum particles

Scientists have created a crystal structure that boosts the interaction between tiny bursts of light and individual electrons, an advance that could be a significant step toward establishing quantum networks in the future.

Quantum kisses change the color of nothing

Even empty gaps have a colour. Now scientists have shown that quantum jumps of electrons can change the colour of gaps between nano-sized balls of gold. The new results, published today in the journal Nature, set a fundamental ...
