Boost for the quantum internet

Details: Published: Tuesday, 23 May 2023

Twenty five years ago, theoretical physicists at the University of Innsbruck made the first proposal on how to transmit quantum information via quantum repeaters over long distances which would open the door to the construction of a worldwide quantum information network. Now, a new generation of Innsbruck researchers has built a quantum repeater node for the standard wavelength of telecommunication networks and transmitted quantum information over tens of kilometers.

Two qudits fully entangled

Recently quantum computers started to work with more than just the zeros and ones we know from classical computers. Now a team at the University of Innsbruck, Austria, demonstrates a way to efficiently create entanglement of such high-dimensional systems to enable more powerful calculations.

EU Flagship project Millenion launched

Details: Published: Wednesday, 19 April 2023

The Millenion project focuses on modular scalability and accessibility aspects of trapped-ion quantum computers, tackling the transition from current laboratory-based experiments to industry-grade quantum computing technologies. 14 academic and industrial leaders across Europe are joining forces to deliver a modular and scalable quantum computing suite with high performance cluster integration and a fault-tolerant register of up to 1000 qubits.

Welcome Bassem Badawi

Details: Published: Monday, 17 April 2023

Welcome Bassem! Bassem joins the cryoteam with a strong background in semiconductor fabrication technologies, in particular lithography and heterogenous integration. In his PhD thesis he developed a mathematical model for an advanced mask fabrication in grayscale lithography processes. With his technological background Bassem will contribute as postdoc to the optical integration in our surface ion traps.

Nuclear alchemy with antimatter

Details: Published: Monday, 17 April 2023

The study of radioisotopes in charged particle traps is a very active field in nuclear physics research. To date, capturing the radioisotopes after synthesis involves a series of production and separation stages that limit the types and lives of species that may be studied. We propose to produce radionuclides directly in the trapping environment as highly charged ions by annihilating atoms with antiprotons.
