Medizinische Hochschule Hannover: Lungencheck auf Rädern 07:05 25.07.2021 Medizinische Hochschule Hannover - Lungencheck im Truck: MHH startet großes Vorsorgeprogramm für Raucher
Lungenkrebs wird oft zu spät erkannt. Um das zu ändern, hat die Medizinische Hochschule Hannover (MHH) jetzt ein großes Vorsorgeprogramm im Verbund mit anderen norddeutschen Kliniken entwickelt. (Ex-)Raucherinnen und Raucher im Alter von 55 bis 79 Jahren können sich beim kostenlosen Check anmelden. Strahlungsarme Untersuchungsmethode: Professor Jens Vogel-Claussen mit Patient Martin Scheele.

In the last few years, several technology companies including Google, Microsoft, and IBM, have massively invested in quantum computing systems based on microwave superconducting circuit platforms in an effort to scale them up from small research-oriented systems to commercialized computing platforms. But fulfilling the potential of quantum computers requires a significant increase in the number of qubits, the building blocks of quantum computers, which can store and manipulate quantum information.
But quantum signals can be contaminated by thermal noise generated by the movement of electrons. To prevent this, superconducting quantum systems must operate at ultra-low temperatures - less than 20 milli-Kelvin - which can be achieved with cryogenic helium-dilution refrigerators.

EPFL scientists have developed ultralow-loss silicon nitride integrated circuits that are central for many photonic devices, such as chip-scale frequency combs, narrow-linewidth lasers, coherent LiDAR, and neuromorphic computing.
Encoding information into light, and transmitting it through optical fibers lies at the core of optical communications. With an incredibly low loss of 0.2 dB/km, optical fibers made from silica have laid the foundations of today’s global telecommunication networks and our information society.
Such ultralow optical loss is equally essential for integrated photonics, which enable the synthesis, processing and detection of optical signals using on-chip waveguides. Today, a number of innovative technologies are based on integrated photonics, including semiconductor lasers,
