Preclinical trials are conducted on non-human subjects (like animals) and in laboratory settings to assess a drug's safety and efficacy before it can be tested on humans.

The application of AI in analyzing biological data and predicting drug efficacy is a significant advancement in the healthcare and pharmaceutical research sectors.

PharmAI's AI capabilities allowed it to analyze complex data and predict drug properties, significantly speeding up the initial stages of identifying potential therapeutic compounds.

Amyloid-beta plaques and tau tangles are the defining pathological hallmarks of Alzheimer's disease, and the AI identified a compound to address these.

Traditional drug discovery is characterized by its immense cost, lengthy development periods, and a high failure rate, which AI seeks to mitigate through faster analysis and prediction.

In QKD, the act of measuring a quantum state (like a photon carrying a key bit) inevitably disturbs it, alerting the legitimate users to the presence of an eavesdropper.

The network is a direct manifestation of India's strategic focus and investment in developing leadership in quantum technologies.

The primary advantage of a quantum communication network is its inherent security, making it ideal for protecting sensitive government and military communications.

Quantum Key Distribution (QKD) uses quantum mechanics to generate and distribute cryptographic keys, ensuring that any eavesdropping attempt is detectable.

Quantum computing utilizes quantum phenomena like superposition (a qubit can be in multiple states simultaneously) and entanglement (two or more qubits are linked in such a way that they share the same fate, regardless of the distance separating them).
