Four superconducting cables link two large quantum processors into one

چار سپر کنڈکٹنگ کیبلز نے دو بڑے کوانٹم پروسیسرز کو ایک بنا دیا

चार सुपरकंडक्टिंग केबलों ने दो बड़े क्वांटम प्रोसेसरों को एक बना दिया

Four superconducting cables link two large quantum processors into one

Key points

اہم نکات

मुख्य बातें

  • IBM researchers have linked two large superconducting quantum processors using four separate superconducting cables, a first step towards building bigger quantum computers from separate chips.
  • The team connected two 120-qubit Nighthawk R1 processors with 80-centimetre aluminium cables, installed after both chips were already in place.
  • Quantum states were transferred across the links with an average accuracy of 99 percent, reaching 99.29 percent on the best link, and operations spanning both processors averaged 94.75 percent.
  • آئی بی ایم کے محققین نے چار الگ سپر کنڈکٹنگ کیبلز کے ذریعے دو بڑے سپر کنڈکٹنگ کوانٹم پروسیسرز کو جوڑ دیا ہے، جو الگ چپس سے بڑے کوانٹم کمپیوٹر بنانے کی طرف ایک قدم ہے۔ ٹیم نے دو 120 کیوبٹ نائٹ ہاک آر ون پروسیسرز کو 80 سینٹی میٹر لمبی ایلومینیم کیبلز سے جوڑا، جو دونوں چپس لگنے کے بعد نصب کی گئیں۔ ان رابطوں کے ذریعے کوانٹم حالتیں اوسطاً 99 فیصد درستگی سے منتقل ہوئیں، بہترین رابطے پر 99.29 فیصد تک، جبکہ دونوں پروسیسرز پر محیط آپریشنز کی اوسط درستگی 94.75 فیصد رہی۔ ٹیم نے دونوں چپس میں مشترکہ الجھی ہوئی حالتیں بھی بنائیں۔ یہ کام ابھی ابتدائی تحقیقی مسودے کے طور پر شائع ہوا ہے، اس کی آزادانہ جانچ باقی ہے، اور یہ کیبلز صرف انتہائی سرد آلات میں کام کرتی ہیں، اس لیے یہ ایک اہم سنگ میل ہے، مکمل کمپیوٹر نہیں۔
  • आईबीएम के शोधकर्ताओं ने चार अलग सुपरकंडक्टिंग केबलों के ज़रिए दो बड़े सुपरकंडक्टिंग क्वांटम प्रोसेसरों को जोड़ दिया है, जो अलग चिपों से बड़े क्वांटम कंप्यूटर बनाने की दिशा में एक कदम है। टीम ने दो 120-क्यूबिट नाइटहॉक आर1 प्रोसेसरों को 80 सेंटीमीटर लंबी एल्युमीनियम केबलों से जोड़ा, जो दोनों चिपों के लगने के बाद स्थापित की गईं। इन लिंकों के ज़रिए क्वांटम अवस्थाएँ औसतन 99 प्रतिशत सटीकता से स्थानांतरित हुईं, सबसे अच्छे लिंक पर 99.29 प्रतिशत तक, जबकि दोनों प्रोसेसरों पर फैले संचालनों की औसत सटीकता 94.75 प्रतिशत रही। टीम ने दोनों चिपों में साझा उलझी हुई अवस्थाएँ भी बनाईं। यह काम अभी प्रारंभिक शोध मसौदे के रूप में प्रकाशित हुआ है, इसकी स्वतंत्र समीक्षा बाकी है, और ये केबलें केवल अत्यंत ठंडे उपकरणों में काम करती हैं, इसलिए यह एक महत्वपूर्ण मील का पत्थर है, तैयार कंप्यूटर नहीं।

IBM researchers have linked two large superconducting quantum processors using four separate superconducting cables, a first step towards building bigger quantum computers from separate chips. The team connected two 120-qubit Nighthawk R1 processors with 80-centimetre aluminium cables, installed after both chips were already in place. Quantum states were transferred across the links with an average accuracy of 99 percent, reaching 99.29 percent on the best link, and operations spanning both processors averaged 94.75 percent. The team also created entangled states shared across both chips. The work, posted as a preprint, is not yet peer-reviewed, and the cables only work inside ultra-cold equipment, so this is a scaling milestone rather than a finished computer.
