Electrical and electronic engineering

EPFL engineers have developed a low-temperature annealing method that maintains the structure of gold and silver when the two metals are combined in an alloy. Their discovery will prove useful in the manufacture of contact lenses, holographic optical elements and other optical components, since the new alloys reflect the full spectral range.

At EPFL, a team of scientists created and observed a new physical phenomenon on an optical chip using modified lights.

Engineers at EPFL have developed a method for reading several qubits – the smallest unit of quantum data – at the same time. Their discovery paves the way to a new generation of even more powerful quantum computers.

Quantum effects in superconductors could give semiconductor technology a new twist. Researchers at the Paul Scherrer Institute PSI and Cornell University in New York State have identified a composite material that could integrate quantum devices into semiconductor technology, making electronic components significantly more powerful. They publish their findings today in the journal Science Advances.
