Quantum technology is developing rapidly and is expected to become a key technology in several areas. KTH is at the forefront of the development of quantum technology, which enables faster and more advanced calculations and opens doors to safer communication, new materials, more efficient energy supply and the development of medicines.

Vaishali Adya
Vaishali Adya is an associate professor and fellow at the Wallenberg Centre for Quantum Technology at KTH. Her research focuses on quantum technology, especially on the development of ‘pinched light’ sources for gravitational wave detectors, biosensors and quantum communication. Vaishali is also the co-leader of the National Quantum Communication Infrastructure in Sweden (NQCIS). This promotes quantum technology and collaboration between research partners and industrial companies and strengthens Sweden's position in quantum communication and secure digital infrastructure.
Quantum computers pose a significant threat to today's digital infrastructure used for digital communication. This means that secret information shared digitally today is vulnerable to so-called ‘harvest now, decrypt later’ attacks, where encrypted data is stolen and stored until a quantum computer is fully developed to decrypt it. Therefore, there is an increasing need for secure solutions, such as quantum key distribution (QKD), which uses quantum mechanics to send information. If the information is intercepted, it is immediately detected and can be dealt with.
David Haviland is a professor at the Department of Quantum and Nano Physics at KTH Royal Institute of Technology. His research involves applying electrical and mechanical oscillators, for example, to construct highly sensitive force sensors that measure the absolute limit determined by the laws of quantum physics. He is also working on experiments that lay the foundation for a new type of quantum computer based on successive measurements on a large network of coupled quantum oscillators. The group's research has laid the foundation for a spin-off company, Intermodulation Products AB, which manufactures and sells specialised measuring instruments for quantum technology.
