In this video, you will find the explanation for the second part of our "qubit types" series: Trapped Ion Qubits.

Trapped ion qubits are a major and promising type of qubit fors quantum computing. They are created by trapping a single ion (an atom or a molecule with an electrical charge) using electromagnetic fields in a vacuum chamber. The trapped ion is then manipulated to represent a qubit, with the two quantum states being encoded in the energy levels of the ion's internal structure.

To perform quantum operations on trapped ion qubits, special lasers are used to manipulate the energy levels of the ion, allowing for the creation of superpositions and entanglement between multiple ions. These operations are highly precise, as the properties of trapped ions are well-understood and easily controlled.

One of the key advantages of trapped ion qubits is their relatively long coherence time up to minutes, which means they can maintain their quantum state for relatively long periods before decoherence occurs. Additionally, trapped ion qubits can be easily scaled up by adding more ions to the trap, allowing for the creation of larger quantum systems.

However, trapped ion qubits are susceptible to decoherence caused by external environmental factors such as magnetic and electric field noise. This can limit their performance and make it challenging to build practical quantum computers. Nonetheless, trapped ion qubits remain an important area of research in quantum computing, with potential applications in areas such as quantum simulation and quantum cryptography.
