Indian Navy to invest in quantum communication for nuclear submarines

-

New Delhi: The Raman Research Institute (RRI) in Bengaluru will collaborate with the combat systems engineering branch of the Indian Navy to create secure communication channels of strategic value utilising quantum technology.

According to a report by Indian Defence Research Wing (IDRW), the RRI had revealed last week that it has successfully used quantum key distribution to show secure communication between a stationary source and a moving receiver.

Quantum communications would offer secure communications for India’s missile submarines, creating the prospect that it could be used to connect with nuclear-armed submarines, even though the Indian Navy aims to utilise it for ship-to-shore communication in the first phase.

The ability to stay in touch with submarines that are a part of India’s nuclear triad not only has strategic value but also guarantees that Indian military planners can direct order a nuclear strike in response to a first strike in the event of war in minutes rather than hours or days, according to US researchers who discovered that quantum communications with submerged objects in turbulent water are possible.

When on patrol, nuclear-armed submarines frequently bury themselves in the vast ocean to ensure that at least some of their nuclear bombs survive any potential first nuclear strike by enemies.

In order to enforce the nuclear grid, India currently operates two nuclear-armed submarines and plans to add two more in the next two to three years. Additionally, India wants to buy five larger submarines with twice the displacement of its current submarines so that they can remain hidden for up to 60 to 70 days at a time.

Both COVID-19 vaccine doses needed for good protection against B16172 variant

-
It’s been a concerning few weeks in the UK, with the B16172 variant first taking hold and then spreading to become dominant. This more infectious form of the virus, initially identified in India, is what we’re now going to have to live with – unless it is out-competed by another variant in the future. Worryingly, experts had predicted that B16172 might be able to escape some of the effects of vaccines, which if true would threaten to derail the UK’s plans to finish lifting restrictions from the end of June. However, Public Health England (PHE) has looked at the ability of various variants to evade immunity and says that the UK’s vaccines remain effective against the variants circulating, including B16172. On the surface, this looks like good news. But delve a bit deeper, and things get more complicated, says Paul Hunter, professor of medicine at the University of East Anglia. PHE’s research found a little drop-off in protection against B16172 among people who were fully vaccinated.

New coronavirus variant emerge in India: How should our COVID response change?

After genome sequencing of over 10,000 COVID-19 cases in India, researchers have discovered a new variant with two new mutations which may be better at evading the immune system. In 15-20 percent of samples from the Indian state of Maharashtra (the state accounting for 62 percent of cases in the country) a new, double mutation in key areas of the virus has been detected. These are now known as the E484Q and L452R mutations. What makes the variant different? Both these mutations are concerning because they are located in a key portion of the virus – the spike protein – that it uses to penetrate human cells. Spike proteins attach via a “receptor binding domain”, meaning the virus can attach to receptors in our cells. These new mutations include changes to the spike protein that make it a “better fit” for human cells. This means the virus can gain entry more easily and multiply faster. Given what we have seen with other similar mutations , it might also make it harder for our immu
