Digital quantum simulations can be used to solve problems in solid-state research, for example conductivity, magnetism or superconductivity.

Quality matters - Advances in digital quantum simulation

The test flight with the unmanned DLR superARTIS helicopter was an important milestone for the 'Upcoming Drones Windfarm' project. The project, which is being carried out by the DLR Institute of Flight Systems together with the energy company EnBW, focuses on the question of whether drones can take over transport tasks for offshore wind farms and relieve maintenance personnel.

Logistics for offshore wind farms could be simplified with the use of drones. DLR is working with energy supplier EnBW to determine requirements and possibilities.

Drones to transport personnel and materials to offshore wind farms

The upgrading of the In-flight Systems and Technology Airborne Research (ISTAR) aircraft will take place in several stages. As an airborne simulator, it is advancing the digitalisation of aeronautics. The research aircraft is based at DLR’s Flight Experiments Facility in Braunschweig, where it is part of the largest civilian research fleet in Europe. Credits: DLR (CC BY-NC-ND 3.0)

ISTAR flights focus on the flight-mechanical and flight-dynamic characteristics of the modified Dassault Falcon 2000LX. Novel sensors measure how the aircraft behaves during specific flight manoeuvres.

Qubits are the processing units of quantum computers. They can be created in various different ways. One option is the creation of solid-state spin qubits in materials such as diamonds, in which qubits get stuck in defects that are specifically inserted into the structure of diamond crystals.

Start-ups grow diamond qubits

Charged atoms cannot escape from an ion trap, as they are confined by an electromagnetic field. A laser, radio waves or microwaves can then change the state of the charged atoms (ions) in a targeted way, so that they become qubits, the building blocks of quantum computers.
