>isnt a Qubit with quantum computers?
What is a qubit?
A qubit, or quantum bit, is the basic unit of information used to encode data in quantum computing. It can be best understood as the quantum equivalent of the traditional bit used by classical computers to encode information in binary.
The term “qubit” is attributed to American theoretical physicist Benjamin Schumacher. Qubits are generally, although not exclusively, created by manipulating and measuring quantum particles (the smallest known building blocks of the physical universe), such as photons, electrons, trapped ions, superconducting circuits and atoms.
Enabled by the unique properties of quantum mechanics, quantum computers use qubits to store more data than traditional bits and vastly improve cryptographic systems. They can also perform advanced computations that would take thousands of years—or even be impossible—for classical supercomputers to complete.
Powered by qubits, quantum computers might soon prove pivotal in addressing many of humanity’s greatest challenges, including cancer and other medical research, climate change, machine learning and artificial intelligence (AI).
