How will quantum technology affect society? What are the challenges and potential innovations? In a series of articles, we take a closer look at the quantum world and report on all the exciting research being conducted at KTH.
The quantum computer – a super machine with challenges
The super machine of the future, the quantum computer, is taking the step from theory to reality. At KTH, research is being conducted on everything from how the hardware itself should be built to what problems a quantum computer can actually solve.

Quantum technology – from theoretical physics to revolutionary technology
Quantum technology is a hot topic right now – and we are said to be on the verge of a revolution. But what exactly is it? KTH professor Mats Wallin explains the concepts.
A practical focus, close contact with researchers and considerable freedom to shape their own education are some of the reasons why Master's students Astrid Bergman and Axel Segendorf have chosen to study quantum technology at KTH. Photo: Jon Lindhe
Why choose to study for a master's degree in quantum technology?
Quantum technology is far from the easiest of subjects – but for some it is the only option. KTH students Astrid Bergman and Axel Segendorf are driven by curiosity and a genuine interest in mathematics – and a desire to help shape the technology of tomorrow.

Quantum keys can keep our secrets safe
Your bank login, your health data, even your private messages – all rely on encryption. But future quantum computers could crack them in seconds. To stay ahead, researchers at KTH are turning to quantum physics itself, developing technology that keep our communication secure for decades to come.
Katia Gallo gives a tour of two laboratories at the Department of Physics at AlbaNova, the hub for the NQCIS pilot facility at KTH. Her team, NQP (Nonlinear and Quantum Photonics), builds, tests and develops components, software and systems for secure and stable quantum communication. They also train new users and teach students quantum technology.
Quantum communication could become the superpower of the future
Katia Gallo, Professor of Photonics, has always been fascinated by the combination of the laws of physics and engineering. She currently coordinates Sweden’s participation in a European initiative to build a quantum communication network.
“We are developing an infrastructure in Sweden that will eventually be linked with those of other EU member states,” she says.
