Quantum computers use qubits, which can exist in multiple states simultaneously, enabling them to solve certain mathematical problems exponentially faster than classical machines. This includes breaking the cryptographic assumptions behind elliptic‑curve…

A futuristic digital illustration symbolizing quantum‑secure blockchain technology. At the center, a glowing padlock with a lattice‑patterned body is encased in a blue wireframe shield, both radiating light. To the left, a 3D blockchain network of interconnected cubes emits teal and blue light; to the right, stacks of digital coins glimmer with circuit engravings. In the background, a golden quantum computer and a blue‑purple quantum waveform hover above a faint cityscape, surrounded by floating binary code and cryptographic formulas. The overall palette blends cool blues and purples with warm golden highlights, conveying advanced cryptographic security.
