As the world progresses further into an era defined by artificial intelligence, cloud architectures, immersive technologies and automation, connectivity forms the crucial backbone enabling this digital transformation. While the present-day Internet suffices for conventional network needs, next-generation quantum computing capabilities demand a revolutionary medium for transmission of highly complex informationflows in the future.
We can envision the concept of a lightning-fast, ultra-secure, global-scale Quantum Internet to push boundaries of speed, encryption strengths and computational power beyond what current frameworks allow for.
Industry Projections
- Quantum networks can achieve data transfer speeds of over 10 Tbps which is 100 times faster than the fastest commercial optical fibers currently operational
- Quantum cryptography facilitated by properties like qubit entanglement can ensure communication security at levels impossible to crack by conventional electronic computers
- Distributed quantum computing by linking quantum processors can enable complex computations like drug design simulations and weather predictions at unprecedented speeds.
2024 onwards, governments and corporations are expected to ramp up testing large-scale quantum communication networks spawning an industry forecast to touch $3 billion globally within a decade.
Key global investments planned
- The EU plans to invest $6.5 billion over 2021-27 on quantum communication infrastructure connecting major cities
- China aims to complete construction of a Beijing-Shanghai quantum network by 2025 under its $10 billion Quantum project
Elaborate Understanding of Quantum Internet
The Quantum Internet constitutes a hypothesized system where activities like routing traffic and transferring data get handled through quantum physics rather than classical means. Its unique value propositions include:
- Unprecedented speeds using quantum entanglement for near instantaneous transfers across vast distances
- Ironclad security by making tapping of communication impossible without detection
- Enabling distributed quantum computing apps requiring pooled resources
Essentially, while the traditional Internet relies on recycling existing infrastructure to continually boost capacity, the Quantum Internet necessitates building an entirely novel underlying architecture right from processors to protocolsoptimized for non-classical information usage needs.
Key Functionalities
The envisioned Quantum Internet aims to facilitate the following broad capabilities which pose limitations on current networks:
- Running complex distributed computing applications like AI/ML, simulations, predictive analytics etc requiring massively powerful collective processing capabilities
- Securely sharing confidential mission-critical data associated with sectors like defense forces, financial institutions, health sector etc.
- Enabling multi-party video conferencing, virtual reality environments and real-time immersive communication at life-like resolutions and minimum lags
The core value thus lies in enabling innovative apps at intersection areas that are constrained today by classical encryption techniques, bandwidth availability and distributed discovery/scheduling methods.
Commercialization Roadmap
While conceptual research on Quantum Internet kicked off as early as 2008, practical rollouts are still at nascent stages worldwide. But appreciable progress by startups and big tech firms alike on enabling technologies like quantum routers, repeaters etc. indicates promising headway.
