In this series of posts powered by The Quantum Insider’s proprietary data platform, we will take a look at the major players in the quantum computing (QC) industry by qubit type. In today’s post, which will be the first of eight, the focus is on trapped ion quantum computing companies whose approach to building a large-scale quantum computer leans on trapped ions.

On the upside, a quantum computer using trapped ions as qubits can operate at room temperature, has very low error rates, and — in theory, at least — is easy to entangle a large number of qubits.

However, there are downsides to using trapped ions: one being they are slow if we compare them to qubits used in other modalities. Another, unfortunately — and this is a big one — is they are difficult to scale due to the complexity of the system, which requires things like vacuums and lasers to control the qubits.

What Is Trapped Ion Quantum Computing?

Trapped Ion Quantum Computing is a method of quantum computing that uses ions (charged atoms) suspended in a magnetic or electric field as qubits (quantum bits) for information processing. It uses ion traps, which are devices that can contain a single ion or multiple ions in order to perform controlled operations on them. These trapped ions are then manipulated using laser beams, electric fields, and magnetic fields in order to process information. By controlling the interactions between these qubits, complex calculations can be performed, allowing for the computation of problems that would otherwise not be possible with classical computing.

As technology advances, Trapped Ion Quantum Computing has the potential to revolutionize computer technology and usher in a new era of completely quantum computing. By harnessing the power of quantum mechanics, trapped ion quantum computers could potentially surpass even the most powerful classical computers in terms of speed, accuracy, and complexity. This could lead to breakthroughs in areas such as artificial intelligence, drug design, cryptography, and much more. As we move forward into the future of computing technologies, Trapped Ion Quantum Computing will play an increasingly important role in pushing the boundaries of what is possible.


6 Trapped Ion Quantum Computing Companies

Below is the list of the 6 leading companies working with trapped ion quantum computing technology. Enjoy!

1. Quantinuum
