Special interest area

Quantum technologies

How do you develop software and algorithms that use the advances in quantum technology? At DIREC quantum is a special interest area, where we explore how digital research can benefit and support the development of quantum technologies.

In parallel with the development of novel hardware for quantum computing, there are many interesting problems that involve advanced computer science.

  • How can we develop algorithms that utilize the possibilities of quantum technologies?
  • How do you best program a quantum computer?
  • Can you transform and optimize program to run efficiently on quantum computers that are limited in size and faulty?
  • Can clever algorithms help mitigate faulty hardware?
  • How do you develop post-quantum cryptography?
  • What kind of data structures are best for supporting quantum computing?
  • How can quantum computing best be integrated into other computer paradigms (HPC – High Performance Computing and GPU – Graphic Processor Unit)?

At DIREC we are working on building and strengthening Danish research in computer science problems related to quantum technologies.

We are actively seeking to grow this community, so please feel free to join our events or reach out to our CEO Thomas Riisgaard Hansen for more information.

Upcoming Quantum Events

We are planning 2-3 events in the next 6 months. Please reach out to get updated on future events.

Lack of digital skills can impede the Danish quantum adventure

29 November 2023
Quantum technology opens up a world of possibilities, but we must acknowledge that the path forward may not necessarily be easy. Denmark can play a crucial role in the development, but to realize this potential, focused investments and, above all, competent digital specialists are needed.

DIREC Quantum Talks

Software Tools for Quantum Computing
Professor Robert Wille

30. September 2022

DIREC TALK: Quantum computers have the potential to solve certain tasks that would take millennia to complete even with the fastest (conventional) supercomputer. However, while impressive accomplishments can be observed in the physical realization of quantum computers, the development of automated methods and software tools that provide assistance in the design and realization of applications for those devices is at risk of not being able to keep up with this development anymore.
