Quantum cryptography is a technique for ensuring the security of communication

Quantum cryptography, also known as quantum encryption, uses quantum mechanics principles to encrypt messages such that they are never read by anybody other than the intended recipient. It takes advantage of quantum's numerous states, as well as its "no change theory," which ensures that it cannot be halted accidentally. These activities require a quantum computer, which can encrypt and decrypt data with enormous computational power. Current public-key cryptography could be swiftly cracked by a quantum computer.

Quantum cryptography is a branch of research that uses quantum mechanics principles to encrypt and transmit data so that hackers even those with quantum computing capabilities can't access it. The invention and execution of numerous cryptographic tasks using the unique capabilities and power of quantum computers is also part of quantum cryptography's larger use. Theoretically, this form of computer can assist in the development of new, stronger, and more efficient encryption systems that would be impossible to construct with current computing and communication architectures.

Why quantum cryptography is important?

Companies and governments all across the world are competing to construct the first practical quantum computer. Some types of computing issues will be much easier to tackle with this technology than with today's traditional computers.

Breaking certain types of encryption, particularly the methods used in today's public key infrastructure (PKI), which underpins virtually all internet interactions, is one of these issues. "I'm terrified of what quantum computing could lead to," says Michael Morris, CEO of Topcoder, a global developer network with 1.4 million members. Topcoder is a subsidiary of Wipro, a worldwide consulting firm. It's also working on overcoming programming hurdles in quantum computing.

"With quantum computing, instead of addressing one problem at a time, we can tackle thousands of problems at the same processing speed and with the same processing power," Morris explains. "Things that take hundreds of days today could be completed in hours on a quantum computer."
