Adding noise for ultimate privacy protection in QKD

A team of physicists of the University of Basel and ETH Zurich have developed the theoretical foundations for a QKD communication protocol that offers ultimate privacy protection and can be implemented experimentally. This protocol guarantees […]

Quantum Legendre-Fenchel Transform

Researchers at EPFL and IBM Quantum present a quantum algorithm to compute the discrete Legendre-Fenchel Transform (LFT). Most currently known quantum algorithms use a few basic building blocks as subroutines. Examples of these building blocks […]

A surprising quantum effect observed in a “large” object

While conducting experiments on a layered metal, EPFL researchers witnessed something very surprising. The unexpected electron behavior they discovered could open up possibilities in the field of quantum computing. In the world of materials science, […]

Playing Pool with Excitons

Semiconductors play an important role, be it in electronics, optoelectronics or photovoltaics. But like other solid bodies, they are quantum many-body systems. Therefore, a calculation of their material properties would overburden conventional computers. Instead, this […]

Quantum Brakes in Molecules

Physicists of the Laboratory for Attosecond Physics have measured the flight times of electrons in molecules after their creation with light. The small quantum particles were emitted from a specific atom within the molecules, which […]

Long-lived pionic helium

MPQ Scientists opened a new window into the quantum world. After eight years they succeeded in a challenging experiment with PSI and CERN: they created an artificial atom, the so-called pionic helium, in which the […]
