Erbium atoms in silicon: A prime candidate for quantum networks

A team of researchers at the Max Planck Institute of Quantum Optics has laid the foundation for the development of future quantum networks. The scientists embedded individual erbium atoms in crystalline silicon, creating ideal conditions for storing and passing on quantum information. more

New Hardware for Quantum Networking

Researchers at the Max-Planck-Institute of Quantum Optics and the Technical University of Munich have demonstrated that individual atoms in a thin crystalline slab can be resolved and individually controlled using light of a precisely adjusted color. This will enable the exchange of quantum information between them in order to create extended quantum networks. more

Light-driven molecular swing

Scientists at the Ludwig-Maximilians-Universität München (LMU) and the Max Planck Institute of Quantum Optics (MPQ) have used ultrashort laser pulses to make the atoms of molecules in a solution vibrate and have gained a precise understanding of the dynamics of energy transfer that take place in the process. more

Entangled photons tailor-made

In order to effectively use a quantum computer, a larger number of specially entangled basic building blocks are needed to carry out computational operations. A team of physicists at MPQ has now for the very first time demonstrated this task with photons emitted by a single atom. Following a novel technique, the researchers generated up to 14 entangled photons in an optical resonator, which ... more

Pumping up the music of molecules

Laser physicists from the attoworld team at Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics have used an optical resonator to amplify the characteristic vibrations of molecules excited by laser pulses in such a way that their identification becomes possible even at very low concentrations. more

Digital holography with multiple colours

With the help of special light sources, the three-dimensional shape and spectrum of objects can be recorded completely without photographic lenses. The trick behind is a highly sophisticated form of interference in space and time. more

How Munich-based start-up planqc wants to be the first to build quantum computers with thousands of qubits

Can a start-up stand a chance against Google or IBM in the race for operable quantum computers? It certainly can. Because so far it is not clear which technology platform will prevail... more

A nanokelvin microwave freezer for molecules

Researchers at MPQ have developed a novel microwave cooling technique for molecular gases. It enables polar molecules to be cooled down to a few nanokelvin, 21 billionths of a degree above absolute zero. In doing so, they set a new low-temperature record and pave the way for new forms of quantum matter that were previously not experimentally accessible. more
