Synchronizing things… That are already in sync…
Scientists have set up the world's most precise 'metronome' for a kilometer-wide network. The timing system synchronizes a 4.7-kilometer-long laser-microwave network with 950 attoseconds precision. An attosecond is a millionth of a millionth of a millionth of a second. (1) Impressive. Or so it seems. Because the problem is not synchronization per se. Everything is…

Memories. For ever (changing)…
Conventional memories used in today's computers only differentiate between the bit values 0 and 1. In quantum physics, however, arbitrary superpositions of these two states are possible. Most of the ideas for new quantum technology devices rely on this "Superposition Principle". One of the main challenges in using such states is that they are usually…

Babies, genome and the urge to "control" things...
Babies’ genomes hold clues that can save their lives, but that same information could be used in far less noble ways. Where should we draw the line? wanders the Popular Science article. (1) Let me spare you the excitement. Nothing can be manipulated as you believe it can. We do not know what life is.…
