#dr #episodic Main samjha. Quantum entanglement ek aisa phenomenon hai jismein do ya zyada quantum particles aise jud jaate hain ki unka naseeb ek ho jaata hai, chahe woh kitni bhi door hon. Jab aap ek entangled particle ki kisi property ko measure karte hain, toh aapko turant dusre particle ki corresponding property ka pata chal jaata hai, bhale hi woh kitni bhi door ho. Yeh aisa hai jaise aapke paas do sikke hon jo jaadui taur par jude hue hon; agar ek head aata hai, toh dusra hamesha tail aayega, aur iske vipreet, bhale hi aap unhein kahin bhi uchalen. Einstein ne ise "spooky action at a distance" kaha tha.
