Speech Title: Block Chain Technologies and Quantum Computing
Abstract: Blockchain technology secures data from modification as it is a distributed ledger which is secured cryptographically. Most of the recent applications are implemented through blockchain and distributed ledger. Among the prevailing technology, cryptocurrency has taken over the finance sector. Though blockchain is ruling the present generation of technology, it is vulnerable to the attacks by quantum computer. The base to implement these technologies is hashing and digital signatures which are susceptible to threats and attacks. The principles of quantum mechanics are applied to build the blocks to enhance security. These principles are the concepts of quantum computing which uses qubits for communication. These encrypted data blocks rely on the laws of physics. As a result this leads to quantum challenge i.e. superposition of quantum states. The computations are performed through photons or qubits which are produced by means of photon’s polarization. These photons are the quantized features used to for encoding the information. Cryptography in quantum computing can be carried out by the principle of uncertainty which is the one of the principle of quantum mechanics. This quantum cryptography through quantum mechanics can be enhanced as quantum key distribution (QKD) in which distantly apart communicators share a common secret key. The QKD implements sharing of common secret key which is then used to implement blocks.
