Quantum Cat Made of 120 Photons ⚡ экспресс
Original: "Deterministic generation of cat states with more than $$100$$ photons under dissipation"
Created a record-breaking quantum "coin": a light pulse of 120 photons spins, showing heads and tails at once, with 96% accuracy.

Quantum 'cats' are states of light that live in two realities at once. The new method creates such a cat from 120 photons (previous record: 40). Even with noise, accuracy is 96%. This is a step toward understanding the quantum boundary and building reliable quantum devices.
🎯 The previous record for cat light was about 40 photons. The new result triples that number.
🎬 In 'The Quantum Thief' by Hannu Rajaniemi, quantum states store identities—large cat states could be a step toward such exotica.
|\text{cat}\rangle = \frac{1}{\sqrt{2}}(|\alpha\rangle + |-\alpha\rangle)
A quantum state where light is simultaneously in two opposite phases, α is the amplitude, |α|² is the average photon number (here > 120).
