NIST physicists have demonstrated a crucial step in using quantum computers to break current encryption codes. They used three beryllium ions to perform a quantum version of the Fourier transform, a process for finding repeating patterns in data. This is the final step in Shor’s algorithm, which could enable quantum computers to factor large numbers exponentially faster than classical computers.
The NIST team’s approach is more efficient than previous demonstrations and paves the way for building large-scale quantum computers using ions as qubits. Quantum computers could solve certain problems much faster than classical computers by harnessing the properties of quantum bits (qubits) that can be in multiple states simultaneously.
The demonstration is an important step towards practical quantum computing, which could have significant implications for cryptography and other fields. However, harnessing the full potential of quantum computing remains extremely challenging due to the delicate nature of quantum states.
