Virtual rail noise - close to reality
Virtual rail noise - close to reality
At Empa, acoustics experts have been investigating for years how noise is generated by passenger and cargo trains - and which technical and structural measures are particularly effective to prevent or at least reduce it. Their findings have now been incorporated into the SILVARSTAR project resulting in a simulation tool for rail noise that can help in practice.

Planting ideas in a computer's head
Planting ideas in a computer’s head
Researchers at ETH Zurich have found a new attack on AMD computer chips in which the attacker plants an "idea" in the computer without it noticing. Using that attack, it was possible to leak data from anywhere in the computer's memory. Everyone has, at one time or another, experienced how dreams can influence our moods and actions.

Schrödinger's cat makes better qubits
Schrödinger's cat makes better qubits
Drawing from Schrödinger's cat thought experiment, scientists at EPFL have built a "critical cat code" qubit that uses bosons to store and process information in a way that is more reliable and resistant to errors than previous qubit designs. Quantum computing uses the principles of quantum mechanics to encode and elaborate data, meaning that it could one day solve computational problems that are intractable with current computers.

'For very small problem sizes a classical computer is faster'
’For very small problem sizes a classical computer is faster’
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. Quantum computers promise to be capable of solving some computational problems much faster than classical computers.

Researchers successfully apply quantum computing in practice
Researchers successfully apply quantum computing in practice
Compared to classical computers, quantum computers can solve complex problems in parallel and thus faster, but they are also more prone to errors. ZHAW researchers show how a hybrid approach can be used to exploit the strengths of quantum computers in a targeted manner. Quantum computers not only know the state 0 and 1, but can also represent several states between 0 and 1 by means of so-called qubits - analogous to bits of classical computers - and thus calculate many possible results simultaneously.

Predict what a mouse sees by decoding brain signals
A research team from EPFL has developed a novel machine-learning algorithm that can reveal the hidden structure in data recorded from the brain, predicting complex information such as what mice see. Is it possible to reconstruct what someone sees based on brain signals alone? The answer is no, not yet.

High-performance detectors to combat spies
High-performance detectors to combat spies
A team from the University of Geneva and ID Quantique has developed single-photon detectors with unprecedented performance. These results open new perspectives for quantum cryptography. How can we combat data theft, which is a real issue for society? Quantum physics has the solution. Its theories make it possible to encode information (a qubit) in single particles of light (a photon) and to circulate them in an optical fibre in a highly secure way.
