Quantum Computing Meaning

Quantum computing is a field of computing based on the principles of quantum mechanics, such as superposition and entanglement. Unlike classical computers, which use bits (0s and 1s), quantum computers use qubits.

This allows them to perform certain types of calculations exponentially faster than even the most powerful supercomputers currently in existence.For the financial and crypto sectors, quantum computing represents a significant systemic risk. Most modern encryption, including the RSA and Elliptic Curve Cryptography (ECC) used by Bitcoin and Ethereum, relies on the mathematical difficulty of factoring large numbers or solving discrete logarithms.

A sufficiently powerful quantum computer could use Shor's Algorithm to break these encryptions in minutes, allowing it to derive a private key from a public address and steal funds.While practical, large-scale quantum computers that can break current encryption do not yet exist, the threat is real enough that researchers are already working on solutions. The transition to quantum-safe protocols is expected to be one of the most significant upgrades in the history of the internet and blockchain technology.
