Quantum computers one step closer

Quantum computers (QC) are one step closer to mass production due to the development of a 2 dimensional ion trap.

Ion traps are a core part of a QC. They seem to be the best way of making qubits (quantum bits, equivalent of an electrical bit). They work by trapping super-cooled ions in an electric field, lasers can then be used to manipulate the ions, changing their quantum state. The advantage of these new traps is that it's easy to manufacture lots of them, so many traps could be connected to make a quantum chip.

The device has been successful when tested with magnesium ions, the next test is to make sure the trap works with ions more suitable for QCs.
