Quantum Computers: A Threat to Blockchain?

How Can a Quantum Computer Pose a Threat?

There are two main concepts behind the quantum computer: superposition and quantum entanglement.

The superposition allows a quantum bit (qbit) to be in several states at the same time, and with the help of quantum entanglement, the observer can find out the parameters of a particle in any position in the universe. The connection is preserved, even if they are moved into different parts of the Universe.

In essence, a quantum computer can process and analyze infinite bits of information at the same time — and so quickly and differently than the human mind cannot grasp it.
