Quantum Computing: Is it the end of the blockchain?

Ajitesh Abhishek Jan 12, 2019

In simple words, a blockchain is a ledger that records transactions of a certain type. It uses mathematical functions such as integer factorization, which is easy to solve in one direction but hard in the other direction for security.


Quantum entanglement is a phenomenon in which the quantum states of two or more objects have to be described with reference to each other, even though the individual objects may be spatially separated.

What’s the future of blockchain in the world of Quantum computing?

One of the potential solutions is Quantum Blockchain, which uses quantum cryptography. This has been proposed by Del Rajan and Matt Visser of Victoria University of Wellington in New Zealand. The idea is simple — if computers can compute fast, make the puzzle more complex.

Alibaba puts quantum computing in the public cloud, follows Intel and IBM’s lead

Alibaba has just announced an 11 qubit quantum computer as part of its cloud offerings, making it the second-fastest public quantum computing platform in the world.

Chinese ecommerce giant Alibaba, in partnership with the Chinese Academy of Sciences, has added quantum computing to its cloud service. Alibaba Cloud now hosts a superconducting cloud computer offering 11 quantum bit (qubit) speed, making it the second fastest in the world behind Intel and IBM’s 20-qubit cloud computer.
