Quantum computers suffer from errors driven by mounting entropy — like dancers in a complex routine gradually losing sync. To keep the dance from falling apart, it's copied across multiple performers — that's how a logical qubit is built from physical ones. Previously, to interact, atoms had to be pulled aside, disrupting the choreography. Now atoms move freely and entangle on the fly, like partners in a nimble tango swapping places without missing a beat. In an experiment with 114 atomic qubits, a simplified version of Peter Shor's algorithm halved the errors, operation chains improved 2–4 times, and a more complex [[16,4,4]] code delivered an 8-fold gain. Such progress became possible thanks to spectroscopy — the art of steering atoms with laser nudges. Interestingly, the chosen dancers aren't plain hydrogen but rubidium or strontium: their energy levels, like dance steps, are handier for such intricate moves.
