Quantum Computing: Are we there yet?

An introduction to quantum computing and a review of the progress we made in the last 5 years.

Andreas Dewes
Five years ago I spoke about my work in quantum computing, building and running a tiny two qubit processor. A few weeks ago, Google announced a potentially groundbreaking result achieved with a 53 qubit quantum processor. I will therefore review the state of experimental quantum computing and discuss the progress we made in the last 5 years. I will explain quantum supremacy, surface code architecture and superconducting quantum processors and show which challenges we still have to overcome to build large scale quantum computers.

We will first dive into the basics of quantum computing and learn about quantum gates, fidelities, error correction and qubit architecture. We will then go through Google’s experiment and try to understand what they actually did and why it matters. We will then see what else we need to build a useful quantum computer, and discuss when that might happen.

Wir verlassen uns in unserem Alltag permanent auf die Verfügbarkeit von elektrischer Energie. Aber wenn wir vom dauerhaften Betrieb von Kraftwerke, die fossile Energieträger verbrennen, wie stellen wir die Versorgung sicher, wenn nachts kein Wind weht? Elektrolyse oder Pumpspeicherkraftwerk? Superkondensatoren oder mechanische Speicher? Was geht heute überhaupt schon? Ähnlich unklar ist die Zukunft der Mobilität, wenn Verbrennungsmotoren von unseren Straßen verschwinden sollen. ...

The Large Hadron Collider (LHC) is the biggest particle accelerator on Earth. It was built to study matter in more detail than ever before and prove physical theories like the Standard Model of Particle Physics. This talk will focus on the engineering aspects of LHC. How was it built? What makes it tick? Which technologies are needed to create a such powerful machine? This talk will take you on a journey to explore how the most complex machine ever built by humans works.

When climate activists say you should listen to the science they usually refer to reports by the Intergovernmental Panel on Climate Change (IPCC). The IPCC is an Intergovernmental organization (IGO) providing an objective summary of scienctific results regarding climate change, its impacts and its reasons. The simulation of future climate is one fundamental pillar within climate research. But what is behind it? How does the science sector look like? How do we gain these insights, what does it ...

Making climate predictions is extremely difficult because climate models cannot simulate every cloud particle in the atmosphere and every wave in the ocean, and the model has no idea what humans will do in the future. I will discuss how we are using the Julia programming language and GPUs in our attempt to build a fast and user-friendly climate model, and improve the accuracy of climate predictions by learning the small-scale physics from observations.

This talk is to show the current state of the discussion on climate change and the necessary and possible changes from a scientific perpesctive. It is to give some typical relevant answers and to foster the resiliance against climate sceptic questioning. This is one of the main tasks the scientist for future are trying to tackle.

Mit 4G wurde gegenüber früheren Mobilfunktechnologien das Air-Interface komplett neu gestaltet. Mit 5G wird dieses nun auf mögliche Zukunftstechnologien erweitert. Wir stellen die Neuerungen und die Möglichkeiten auf dem 5G-Air-Interface und im Core-Netz gegenüber 4G vor.
