In computer science and technology, the term “quantum computing” has emerged as a buzzword, capturing the imagination of scientists, engineers, and enthusiasts alike. But what exactly is a quantum computer, and how does it differ from classical computers?

Most of us remember Y2K. The global Y2K project aimed to replace the two-digit year codes with four-digit codes by December 31, 1999, to ensure that computers didn’t think the year was 1900 and bring the world to a halt. We successfully navigated the problem. At the tick of 00:00:01 on January 1, 2000, the world functioned as usual.

Understand what a kill switch is, its evolution, impact, cybersecurity perspectives about kill switches & available quantum solutions.

At the core of quantum mechanics is the idea that particles, such as electrons and photons, can exist in multiple states simultaneously. Unlike classical physics, where an object can only exist in one state at a time, quantum superposition allows particles to exist in a combination of states.

Quantum computers use fundamental principles of quantum mechanics to solve complex problems in a matter of seconds (which otherwise would take several years). Once a quantum computer achieves a scale large enough to crack RSA encryption protocols, all of our online data is under threat.

As the digital landscape evolves, the threat of quantum computing to conventional encryption methods becomes increasingly real. Quantum computers, with their ability to solve complex problems exponentially faster than classical computers, pose a significant risk to the encryption algorithms that currently safeguard our data.

Quantum computers use the laws of quantum mechanics to process information in quantum bits or qubits. Qubits can exist in multiple states at the same time (called quantum superposition). This property allows quantum computers to process data and solve problems exponentially faster than classical computers.

Find out how leading banks are preparing for the quantum future, based on the World Economic Forum’s July 2025 report exclusive to the BFSI industry.

Companies and governments around the world are in a race to build the first usable quantum computer. The technology promises to make some kinds of computing problems much, much easier to solve than with today’s classical computers, but it also poses a significant threat to the integrity of encrypted data.

QNu Labs was found in 2016 IIT Chennai, Now Trailblazers in quantum cryptography, quantum encryption, and quantum communication solutions.

The dynamics of geopolitics change over time; it is not a new phenomenon. Therefore, all data and transactions on the internet are encrypted. The widely used encryption method (RSA protocol) uses encryption keys to securely transmit data globally. An encryption key is a random string of bits used to encode and decode data. Each key is unique and unpredictable.

Superposition is one of the most iconic concepts in quantum physics. The principle says that the particles such as electrons can exist in multiple positions simultaneously. For example, imagine a coin tossed in the air—it is not in a definite state of heads or tails while in the air until it is observed. Similarly, sub-atomic particles in quantum superposition exist in all possible states until they are measured.

At QNu Labs, we're dedicated to unraveling the complexities of the quantum realm and translating those insights into tangible cybersecurity solutions.

The process of encrypting data is called cryptography. It converts plain text into scrambled text so that someone with the right “key” can read it. Quantum cryptography, by extension, uses the principles of quantum mechanics to encrypt data and transmit it securely.

Data sent over public communication channels are secured using cryptography. It protects all kinds of electronic communications as well as passwords, digital signatures, and health records. The advent of quantum computers has put cybersecurity under a state of alarm. Large-scale quantum computers have the power to break public key encryption.

Quantum computing uses fundamental principles of quantum mechanics to perform complex processing. Quantum cryptography leverages the same principles for advanced data encryption. However, quantum computing and quantum cryptography are not allies. Instead, they stand tall against each other at the crossroads!
