QIA Successfully Entangles Two Ions for Long-Distance Quantum Networks

Two ions have been entangled within 230 metres by a team led by QIA members Tracy Northup and Ben Lanyon from QIA Partner, University of Innsbruck. The research shows that the trapped ions are the possible building blocks for future quantum networks that will eventually connect cities and even entire continents.

One of the most important systems for creating quantum computers and other quantum technologies is trapped ions, which are only ever entangled in one particular laboratory. Interfaces that can transmit quantum information are needed to connect those various quantum systems.

Two laboratories, one in the building of the Department of Experimental Physics and another at the Institute of Quantum Optics and Quantum Information of the Austrian Academy of Sciences, were used to set up the two quantum systems.

The use of trapped ions as a platform for long-distance quantum networks has the potential to revolutionise the field of quantum computing. Traditional quantum computing methods rely on the use of atoms or photons, which are difficult to control and manipulate remotely. On the other hand, the use of trapped ions allows for the creation of more stable and controllable quantum systems that can be used for a variety of applications, including quantum communication and quantum cryptography.
