In quantum mechanics, the act of measurement produces unavoidable perturbation (also called “back-action”) on the state of the measured system. This effect is, in many cases, not desirable, as back-action often limits the precision of repeated measurements. However, so-called Quantum Non-Demolition (QND) measurements ensure that the unavoidable and deleterious back-action is diverted onto other system […]
Developing non-classical light sources that can emit, on-demand, exactly one photon at a time is one of the main requirements of quantum technologies. But although the first demonstration of such a “single photon emitter”, or SPE, dates back to the 1970s, their low reliability and efficiency has been stood in the way of any meaningfully […]
Lausanne, Switzerland and Corbeil-Essones, France – April 27, 2022 LIGENTEC SA, the leading supplier of high performance, low loss, silicon nitride Photonic Integrated Circuits established a R&D Centre in France. Photonic integrated circuits (PICs) are ready to repeat the success story of electronic integrated circuits (ICs). PICs work with light instead of electrons and will […]
Terra Quantum AG announces that it has extended its Series A funding round to $75m, as well as its research offering a ground-breaking solution to the longstanding challenge of efficient power devices for nanoelectronics. Terra Quantum is the first company to reveal the underlying mechanism of ferroelectric-based negative capacitance while also sharing methods for its practical […]
Q-CTRL has announced a partnership with The Paul Scherrer Institute (PSI), Switzerland’s largest research institute for natural and engineering sciences, to pioneer R&D in the scale-up of quantum computers. The strategic partnership will leverage Q-CTRL and PSI’s combined expertise to deliver transformational capabilities to the broader research community. This partnership builds on the collaboration of […]
Computers, smartphones, GPS: quantum physics has enabled many technological advances. It is now opening up new fields of research in cryptography (the art of coding messages) with the aim of developing ultra-secure telecommunications networks. There is one obstacle, however: after a few hundred kilometers within an optical fiber, the photons that carry the qubits or […]
A team of scientists at CERN led by MPQ physicist Masaki Hori has found that a hybrid antimatter-matter atom behaves in an unexpected way when submerged in superfluid helium. The result may open a new way for antimatter to be used to study the properties of condensed matter, or to search for antimatter in cosmic […]

(Photo: ETH Zurich/D-PHYS Home group) In modern computing devices, literally billions of transistors work restlessly in almost perfect harmony. The keys to producing near-perfect computation from devices made from imperfect components are the use of […]
Artistic rendering of a graphene nanoribbon adsorbed on a gold surface and probed with the sharp tip of a scanning tunneling microscope. These tailor made carbon structures exhibit quantum effects that are stable and can be manipulated even at room temperature. That could be a silver bullet for building entirely new kinds of quantum computers. […]
