Code Report: Quantum Computing Overview

Introduction

• Elcapitan, world's largest supercomputer with 1 million CPU cores and 10 million GPU cores.
• Google unveiled a Quantum chip named Willow, considerably faster for certain problems than Elcapitan.

Quantum Computing Developments

• Google Willow Chip:

  • Fits in the palm of your hand.
  • Can solve problems septillions of times faster than Elcapitan.
  • Error correction & reconfiguration capabilities.

• China's Superconducting Chip:

  • 504 Cubit record-breaking chip.
  • Concerns over breaking encryption algorithms.

Comparison and Concerns

• Quantum computing could potentially crack encryption like RSA, posing a threat to internet security.
• Requires understanding how Quantum Computing works compared to classical computers.

How Quantum Computing Works

• Classical Computers:

  • Use bits (zeros and ones) for processing information.

• Quantum Computers:

  • Use Quantum bits (qubits), which can represent the superposition of multiple states simultaneously.
  • Entanglement allows computations that are interlinked despite physical distance.
  • Quantum Gates coordinate these operations using quantum mechanics principles.

Challenges in Quantum Computing

• Qubits are delicate with high error rates and need temperatures near absolute zero to operate.
• Willow chip reduces error rate by finding high error qubits and reconfiguring them.
• Qubits maintain superposition state temporarily (~100 microseconds on Willow).

Applications and Future

• Algorithms like Shor's can factor large numbers but need quantum hardware to run efficiently.
• Quantum computers around 2,000 qubits could break common encryption systems.
• Chinese chip with 504 qubits is noteworthy; watch for error rate improvements for exponential scale-up.

Conclusion

• Quantum computing holds utopian potential and existential threats.
• Continuous improvements and breakthroughs in this field are necessary.
• Developer community urged to stay informed via platforms like Daily.dev.
