An easier way to learn quantum processes
Research
EPFL
EPFL scientists show that even a few simple examples are enough for a quantum machine-learning model, the “quantum neural networks”, to learn and predict the behavior of quantum systems, bringing us closer to a new era of quantum computing.
An unexpected antenna for nanoscale light sources
Research
ETH Zurich Empa
Researchers at ETH have created an antenna for light sources on a chip using an unusual placement of a semiconductor material. In the future, efficient nanoscale LEDs and lasers could be produced in this way.
“For very small problem sizes a classical computer is faster”
Research
ETH Zurich
In theory, quantum computers vastly outperform classical computers in terms of computing speed. For them to do so in practice, it is necessary to design more and novel high-speed algorithms, says ETH supercomputing specialist Torsten Hoefler.  
Entangled quantum circuits
Research
ETH Zurich
ETH Zurich researchers have succeeding in demonstrating that quantum mechanical objects that are far apart can be much more strongly correlated with each other than is possible in conventional systems. For this experiment, they used superconducting circuits for the first time.
Fat quantum cats
Research
ETH Zurich
Researchers at ETH Zurich have created the heaviest Schrödinger cat to date by putting a crystal in a superposition of two oscillation states. Their results could lead to more robust quantum bits and help to explain why quantum superpositions are not observed in everyday life.
