Entanglement is a central phenomenon of quantum mechanics. It enables two photons to be connected with each other regardless of distance, and it is the basis of the immense potential of quantum technologies. However, the continuing development of qua
In September 2020, researchers at Aalto University and VTT revealed that they had developed a high-speed nano-scale radiation detector a bolometer fast enough to read the qubits in a quantum computer.Now, Professor Mikko Möttönen’s team and their par

A joint group of scientists from Finland, Russia, China and the USA have demonstrated that temperature difference can be used to entangle pairs of electrons in superconducting structures. The experimental discovery, published in
Nature Communications, promises powerful applications in quantum devices, bringing us one step closer towards applications of the second quantum revolution.
The team, led by Professor Pertti Hakonen from Aalto University, has shown that the thermoelectric effect provides a new method for producing entangled electrons in a new device. Quantum entanglement is the cornerstone of the novel quantum technologies. This concept, however, has puzzled many physicists over the years, including Albert Einstein who worr
