Quantum computing is emerging as both a potential technological breakthrough and a critical threat to current cryptographic systems. Experts warn that large quantum computers could break most existing encryption protocols within seconds using algorithms like Shor's algorithm, posing a 'store now, decrypt later' risk to cybersecurity. Microsoft is actively addressing this challenge by advancing next-generation cryptography to counter quantum threats. The global community is urged to prepare for the imminent quantum era, as the timeline for quantum computing's impact on encryption and digital assets like Bitcoin is estimated to be within three to ten years. This accelerated timeline highlights the urgency to select and implement effective cryptographic solutions to safeguard digital infrastructure before quantum computing capabilities become widespread.
