Now, a team led by scientists from ETH Zurich has proposed a new ion trap that promises to enable scalability far beyond current capabilities. The study’s findings are published in Nature.

The design provides straightforward indexing and assembly of the trap electrodes, with large solid angle access to the ion. Four extra electrodes were placed on a circle between the grounded plane ...

By adding an oscillating electromagnetic field, on the other hand, one obtains a stable ion trap, also known as a Paul trap. In this way, it has been possible in recent years to build quantum ...

The charge on an ion makes it easy to use electric fields to hold them in place. Indeed, if you trap a group of ions, they naturally form up in regularly spaced arrays, making it really easy to ...

Five on a line: an ion trap with four segmented blade electrodes used to trap a linear chain of atomic ions for quantum-information processing. Each ion is addressed optically for individual control ...

The first adjustable “ion trap” could help scientists better understand the challenges of building practical quantum computers, researchers say. Conventional ion traps confine atomic particles ...

One photographer, David Nadlinger, used a standard digital camera — but he had some help setting up the shot courtesy of Oxford's Ion Trap Quantum Computing lab, where he is researching for his ...

Microsoft and Quantinuum today announced a major breakthrough in quantum error correction. Using Quantinuum’s ion-trap hardware and Microsoft’s new qubit ...

Here we realize a micro-fabricated Penning ion trap that removes these restrictions by replacing the radio-frequency field with a 3 T magnetic field. We demonstrate full quantum control of an ion in ...

Researchers at ETH have now created an ion trap on a microfabricated chip using only static fields – an electric field and a magnetic field – in which quantum operations can be performed. In this trap ...
