What is a Trapped-ion Quantum Computer?
A trapped-ion quantum computer is a type of quantum computing device that uses individual ions (electrically charged atoms) as qubits, or quantum bits. These ions are trapped in electromagnetic fields and cooled to extremely low temperatures, allowing for precise control over their quantum states.
History
The concept of trapped-ion quantum computing dates back to the 1980s, when physicists first proposed using ion traps to study atomic physics. However, it wasn't until the 1990s that the first experimental demonstrations of trapped-ion quantum computing were performed. Since then, significant progress has been made in developing and scaling up trapped-ion quantum computers.
Key Facts
