Quantum cryptography is the science of exploiting quantum mechanical properties to perform cryptographic tasks. The best known example of quantum cryptography is quantum key distribution which offers an information-theoretically secure solution to the key exchange problem.

Speaker: Noah Stephens-Davidowitz, MIT Abstract: Much of the internet relies on public-key cryptographic protocols to keep sensitive information private. Unfortunately, the protocols that we currently use are known to be vulnerable to attackers with quantum computers. Recent advancement in quantum computing has therefore started a bit of a rush toContinue Reading

Speaker: Divesh Aggarwal, Centre for Quantum Technologies, NUS Abstract: Lattice-based cryptosystems are perhaps the most promising candidates for post-quantum cryptography as they have strong security proofs based on worst-case hardness of computational lattice problems and are efficient to implement due to their parallelizable structure. Attempts to solve lattice problems byContinue Reading

Quantum Cryptography explained simply. Regular encryption is breakable, but not quantum cryptography. Today we’ll look at the simplest case of quantum cryptography, quantum key distribution. It uses the Heisenberg Uncertainty Principle to prevent eavesdroppers from cracking the code. Hi! I’m Jade. Subscribe to Up and Atom for new physics, mathContinue Reading

It’s extremely expensive, has no means to be routed or authenticated and the existing Internet works perfectly fine with existing cryptographic and authentication methods. This whole industry is a complete scam, which is costing companies tons of money to pointless retool their security. “For public key encryption, such as thatContinue Reading

This animation by the Centre for Quantum Technologies at the National University of Singapore illustrates the process of quantum key distribution using entangled photons. The goal is for two people in different places to end up with identical keys by measuring these photons. We want these people – usually givenContinue Reading
