SCIENCE CURRENT AFFAIRS DECEMBER 2025– QUANTUM COMPUTING & INFORMATION BREAKTHROUGHS
1. Major Advancement in Quantum Processing
Scientists have developed a new type of quantum processor using tantalum on silicon that extends qubit coherence time significantly — up to 15 times longer than existing designs used by Google & IBM.
- Quantum coherence time is critical for reliable quantum computation because it determines how long quantum information can be stored and used before degrading.
- This breakthrough could lead to much more powerful and stable quantum computers, accelerating applications in cryptography, optimization, drug discovery, and materials science.
- Challenges remain around material scalability and scarcity of tantalum.
2. Quantum Teleportation Milestone
Researchers at the University of Stuttgart successfully demonstrated quantum teleportation of a photon’s polarization state over a measurable distance (~32 feet).
-
This experiment uses quantum entanglement — a fundamental quantum phenomenon where particles remain linked regardless of distance.
-
Though not teleporting matter or humans, this paves the way for practical quantum communication networks that are virtually unhackable.
-
Long-term goal: development of a quantum internet enabling secure data transfer and synchronized quantum systems.
3. Broader Global Science Context
While quantum advances are transforming computing and communication, health science has also seen significant progress in 2025:
-
Five major global health wins are projected to save millions of lives, including a breakthrough new antimalarial drug, HIV prevention shots, and progress on TB diagnostics & vaccines.
