Hunting Dark Matter with Qubits ⚡ экспресс
Like an ultrasensitive microphone, transmon quantum devices pick up the faint 'knock' of dark matter particles while remaining deaf to ordinary noise. Scientists noticed these devices sometimes lose stability for no apparent reason, and linked it to dark matter impacts. So, could the invisible Universe be signaling us through quantum glitches?
Dark matter is an invisible substance, five times more abundant in the universe than ordinary matter. Its particles barely touch atoms, but occasionally they can nudge an electron—like a string brushed by the wind.
At ultra-low temperatures, qubits in quantum computers are like taut strings: the slightest disturbance snaps their pure 'sound'. A dark matter particle colliding with an electron in such a device causes a jitter, increasing entropy and breaking the signal. John Bardeen explained superconductivity—the key to their operation.
By listening to this jitter in dozens of experiments, scientists filtered out ordinary noise and found a contribution that doesn't fit known physics. Thus they set record constraints on the properties of dark matter particles and their scattering off electrons, going beyond the Standard Model.
🎯 The energy from a dark matter particle's impact is so tiny it could only lift a grain of sand by the thickness of a human hair—yet even this drop disrupts the quantum string.
🎬 Science fiction writers dreamed of detectors for ghost particles. Quantum strings turned fantasy into reality, letting us hear the silent cosmos.
