Dr. Anya Sharma is from India, and her recognition signifies India's increasing strength in advanced scientific research.

The development of error-correction mechanisms for qubits is crucial for building stable and functional quantum computers, and this was a focus of the laureates' work.

The EPR paradox, proposed by Einstein, Podolsky, and Rosen, was a thought experiment questioning the completeness of quantum mechanics, specifically related to entanglement.

The prize focuses on advancements in quantum technologies like communication, computing, and simulations, not fossil fuel extraction.

The prize was awarded for work related to harnessing quantum entanglement for practical applications.

As marine species struggle to survive or migrate away from low-oxygen areas, fisheries are negatively impacted, affecting the livelihoods of millions in coastal communities.

Deoxygenated environments can become sites for the production of nitrous oxide (N2O), a greenhouse gas with a much higher warming potential than CO2.

Dead zones are regions in the ocean where oxygen levels have dropped so low that most marine organisms, especially fish and crustaceans, cannot survive.

Warmer water holds less dissolved oxygen, and nutrient pollution from land leads to algal blooms that consume oxygen when they decompose, both contributing significantly to deoxygenation.

Ocean deoxygenation refers to the alarming decline in the amount of dissolved oxygen in the world's oceans.
