Protecting children from dangerous viruses with oral vaccines

Orally administered vaccine can protect millions from hepatitis B. Oral vaccines are both safer and less expensive than injections. Therefore, researchers are continuously pursuing ways to produce an oral vaccine that is sufficiently effective. Now, University of Copenhagen physicists have delivered virologists a “recipe” for improving vaccine drops using methods from the world of nanophysics.

A quantum leap merges nano-opto-mechanics and quantum photonics in a device one tenth the size of a human hair

University of Copenhagen researchers have developed a nanocomponent that emits light particles carrying quantum information. Less than one-tenth the width of a human hair, the miniscule component makes it possible to scale up and could ultimately reach the capabilities required for a quantum computer or quantum internet. The research result puts Denmark at the head

Quantum computing takes another solid step

A world-record result in reducing errors in semiconductor electron ‘spin qubits’, a type of building block for quantum computers, has been achieved using the theoretical work of quantum physicists at the University of Sydney Nano Institute and School of Physics. The experimental result by UNSW engineers demonstrated error rates as low as 0.043 percent, lower

New discovery may have profound implications for the architecture of solid-state quantum computers

At the Niels Bohr Institute, University of Copenhagen, researchers have realized the swap of electron spins between distant quantum dots. The discovery brings us a step closer to future applications of quantum information, as the tiny dots have to leave enough room on the microchip for delicate control electrodes. The distance between the dots has

Step by step: New building material for quantum computers

A Danish-American research team has shown that it is possible to produce ‘Majorana particles’ in a new ‘building material’. The research, led by scientists from Niels Bohr institute, University of Copenhagen, paves the road for new types of experiments – and at the same time represents an important contribution to the construction of the information

Sensor Turns Faintest Radio Waves into Laser Signals

The supersensitive device holds promise for medical imaging and quantum networks Physicists have found a way to detect faint radio waves and convert them directly into signals that can be transmitted by fiber optics. The discovery could improve the sensitivity of detectors used in magnetic resonance imaging and radio astronomy, and help to connect future

Environmentally friendly cement is stronger than ordinary cement

New research from the Niels Bohr Institute shows that cement made with waste ash from sugar production is stronger than ordinary cement. The research shows that the ash helps to bind water in the cement so that it is stronger, can withstand higher pressure and crumbles less. At the same time, energy is saved and

Quantum teleportation between atomic systems over long distances

The stable results are an important step towards the quantum communication network of the future. Researchers have been able to teleport information from light to light at a quantum level for several years. In 2006, researchers at the Niels Bohr Institute succeeded in teleporting between light and gas atoms. Now the research group has succeeded

Quantum Optical Link Sets New Time Records

Quantum communication could be an option for the absolutely secure transfer of data. The key component in quantum communication over long distances is the special phenomenon called entanglement between two atomic systems. Entanglement between two atomic systems is very fragile and up until now researchers have only been able to maintain the entanglement for a
