Quantum Record: 120 Entangled Qubits ⚡ экспресс
Picture this: 120 tiny particles acting like one perfectly coordinated choir. For the first time, scientists have managed to 'sing' a quantum song with such a large ensemble of qubits—it's like getting 120 pendulums to swing together perfectly. Each one helps check the quality of future quantum computers. Will we ever be able to 'tune' a thousand such particles?
Picture an orchestra of 120 musicians playing in perfect unison—one false note and the harmony crumbles. That's the metaphor for a record-breaking quantum ensemble. Physicists have for the first time entangled 120 superconducting qubits, the building blocks of future computers. These qubits operate only at near absolute zero temperatures and look like miniature antennas visible to the naked eye. This state, dubbed a 'Schrödinger's cat' after Erwin Schrödinger, binds 120 objects into one whole where each, like the legendary cat, exists in two states at once.
The fragility of quantum linkage is like a delicate melody in the wind—the slightest breeze, or thermal noise, sows chaos. To keep the tune, scientists pulled a clever trick: they briefly loosened the connections, caught the errors, and tightened the particles back into unison. Even with 56% accuracy, it's a breakthrough for 120 elements.
These experiments aren't just a numbers game. They'll help create powerful algorithms and might even explain the link between spacetime curvature and black holes. Research involving Anton Zeilinger brings us closer to an era of reliable quantum machines.
🎯 The experiment took place in complete darkness at temperatures a fraction of a degree above absolute zero—a stray photon would have shattered the delicate quantum balance.
🎬 Instant communication via entangled particles is a staple of sci-fi. In Ursula K. Le Guin's novels, the 'ansible' device allowed interstellar conversations, even though real physics forbids faster-than-light information transfer.
