Industries such as banking, healthcare, power grids, and telecom (critical digital infrastructure) are at risk as quantum computers become more powerful, and the potential for systems compromise in these industries continues to grow with every passing day.

Quantum cryptography is no longer a buzzword. The field of cryptography is undergoing a massive overhaul in the quantum era. The anticipation of the launch of a fault-tolerant quantum computer has made cryptographers wake up and take notice.

In cybersecurity, where data protection is paramount, traditional cryptographic methods have long been the stalwart guardians of sensitive information. However, as computing power advances, so too do the tools available to potential attackers. In the ever-evolving landscape, the emergence of quantum cryptography offers a promising solution to the challenges of secure communication in the digital age.

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!

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.

A quantum computer can process data at an enormous speed. A transaction that takes classical computers weeks to compute can be processed by a quantum computer in seconds. The ability of quantum computers to factor many possibilities simultaneously has severe implications for data privacy. Data attacks with advanced quantum technologies could crack even the most advanced encryption schemes.

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.

The Indian Cabinet recently approved the National Quantum Mission. The mission is essential for building excellence in national quantum security and developing quantum computers, quantum communication, new materials, quantum sensors, and quantum cryptography.

Data is the engine of the new economy. The data economy depends on the creation of data and data sharing. This makes data an invaluable asset for nations, enterprises and individuals. The data exchange fuels data harvesting. Companies and individuals are known to harvest data - extract useful information from data sources for their personal benefit.

Before understanding Quantum Key Distribution (QKD), let us understand quantum cryptography. Cryptography is the process of encrypting and protecting data such that only the person with the right secret key can decrypt it. Quantum cryptography is a process of encryption using properties of quantum mechanics to transmit data securely, making it hack-proof.

boAt, an Indian electronics company, reportedly faced a major breach that affected more than 7 million of its customers. Media reports pointed out that personal details like names, email addresses, phone numbers, and even their residential addresses were exposed.

A quantum computer is a computing technology that uses sub-atomic particles and the principles of quantum mechanics to perform exponentially faster computations than existing computers. Quantum computing has many applications in healthcare, such as protein folding. However, the technology also has the power to break today’s encryption protocols that secure data and critical systems.

Quantum computing (QC) garners a lot of positive press due to its power to solve complex computations several times faster. It is envisioned that QC can be a critical enabler and a strong catalyst to considerably reduce the computational power required to perform complex calculations and boost the future of sixth-generation (6G) communication.

Countries around the world are adopting quantum technologies at a rapid rate. India announced the National Quantum Mission to demonstrate the government’s dedication to advancing quantum science in the country and hint at quantum priorities.

Encryption, a crucial digital security practice, conceals information from unauthorized access by establishing entry parameters, akin to a password for data retrieval. It involves transforming data into an unreadable format using intricate algorithms, rendering it inaccessible to unauthorized entities.

The Signal Protocol is a set of cryptographic specifications that provides end-to-end encryption for private communications exchanged daily by billions of people around the world. The team announced on their blog that they are upgrading the X3DH specification to PQXDH, a first step in advancing quantum resistance in the Signal protocol.

The objective of the mission is to seed, nurture and scale up scientific and industrial R&D and create a vibrant and innovative ecosystem in Quantum Technology (QT). It will accelerate QT-led economic growth, nurture the ecosystem in the country, and make India one of the leading nations in the development of Quantum Technologies & Applications (QTA).
