As mid-career resets go, investment banker Srinivasa Rao Aluri’s was nothing out of the ordinary. After 16 years as an investor, Aluri was bowing to burnout, but also keeping an eagle eye on the next big thing. While still at US-based bank Morgan Stanley, when deal-making was getting to him, Aluri had enrolled in the first batch of Global Executive Leadership Programme at Yale University in the country. During this time, he also spent time at the Singularity University on the west coast near Stanford. Seeds were sown at Singularity but saplings grew when he later spent a month as a monk at a monastery in Nepal. 

That was 2016. 

Four years later, in the middle of a raging pandemic, Aluri doesn’t tire of talking about cyber security. QNu Labs, which he floated in 2017 after months of inner and outer search, has built deployable products for quantum security that only a handful of companies in the world can lay claim to. As geopolitical tensions escalate, hack-proof technologies, which seemed distant and tailor-made for the defence, suddenly look appealing for civilian use. 

When we started QNu, says Aluri, I had five years in mind. “Everyone told me it’s a while away. But everything changed with Google claiming quantum supremacy quantum supremacy Google AI Blog Quantum Supremacy Using a Programmable Superconducting Processor Read more in September. Suddenly quantum computers looked real; that made our proposition strong.” 

If a quantum computer is real, all encryption that exists today, no matter where, can be broken in no time. 

Digital communications, from messaging services like WhatsApp and ShareChat to online banking, e-commerce to mobile transactions, all have some underlying encryption. It is built on the premise that the algorithms, which scramble data from the sender to the receiver, are based on hard mathematical problems that require humongous computing power to crack. 

With quantum computing—a new kind of computing based on the laws of quantum mechanics—all such algorithms can be easily cracked. Simply put, mathematical hardness, or factoring of large prime numbers, dissolves in the face of the brute number-crunching prowess of a quantum computer. 

When Aluri started, he had no clue about quantum. Or electronics. But he did it because he thought it was an idea whose time had come. He asked himself, if he can’t do it with his money and network, who will do it?

Countries like Israel and China are ahead in developing quantum cryptography. Others need to catch up, or, as the Quantum Alliance Initiative (QAI) at the Hudson Institute Hudson Institute Quantum Alliance Initiative Read more  in Washington shows, band together.

What is The Ken?

The Ken is a subscription-only business journalism website and app that provides coverage across two editions - India and Southeast Asia.

What kind of stories do you write?

We publish sharp, original and reported stories on technology, business and healthcare. Our stories are forward-looking, analytical and directional — supported by data, visualisations and infographics.

We use language and narrative that is accessible to even lay readers. And we optimise for quality over quantity, every single time.

What do I get if I subscribe?

For subscribers of the India edition, we publish a new story every weekday, a premium daily newsletter, Beyond The First Order and a weekly newsletter - The Nutgraf.

For subscribers of the Southeast Asia edition, we publish a new story three days a week and a weekly newsletter, Strait Up.

The annual subscription will get you complete, exclusive access to our archive of previously published stories for your edition, along with access to our subscriber-only mobile apps, our premium comment sections, our newsletter archives and several other gifts and benefits.

Do I need to pay separately for your premium newsletters?

Nope. Paid, premium subscribers of The Ken get our newsletters delivered for free.

Does a subscription to the India edition grant me access to Southeast Asia stories? Or vice-versa?

Afraid not. Each edition is separate with its own subscription plan. The India edition publishes stories focused on India. The Southeast Asia edition is focused on Southeast Asia. We may occasionally cross-publish stories from one edition to the other.

Do you offer an all-access joint subscription for both editions?

Not yet. If you’d like to access both editions, you’ll have to purchase two subscriptions separately - one for India and the other for Southeast Asia.

Do you offer any discounts?

No. We have a zero discounts policy.

Is there a free trial I can opt for?

We don’t offer any trials, but you can sign up for a free account which will give you access to the weekly free story, our archive of free stories and summaries of the paid stories. You can stay on the free account as long as you’d like.

Do you offer refunds?

We allow you to sample our journalism for free before signing up, and after you do, we stand by its quality. But we do not offer refunds.
