Swiss Technology Enables Cloud Based Photonic Quantum Computer
Quantum computers promise to solve problems that are impossible to compute by today's supercomputers. The race for the best quantum computing technology is underway, many technologies are complex and require cryogenic cooling. Photonics approaches have so far been considered impractical because of difficulties in generating the required quantum states, or the transformations of such states, on demand.
Canadian based Xanadu now reported in the Nature magazine a programmable, cloud accessible and scalable photonic circuit able to operate different types of quantum algorithms. Future applications are for example in the development of new drugs.
A photonic circuit is similar to an electrical IC, but uses photons instead of electrons. These photons are guided by optical waveguides, tiny structures carefully etched on the chip. The special feature of this photonic chip is its extremely low propagation loss and special material properties, finally enabling the desired quantum states.
The photonic quantum chip was manufactured by Swiss based LIGENTEC SA with its unique and scalable Silicon Nitride Photonics technology. “We are extremely excited to see this groundbreaking milestone in photonic quantum computing to be achieved by our customer” states Michael Geiselmann, co-founder of LIGENTEC. “We are also proud to have contributed to this achievement. This is the result of years of hard work and will be only the beginning of a great future for photonic integrated circuits”. LIGENTEC's unique photonic chip technology has unique advantages not only in quantum computing but also in
LiDAR for autonomous driving, pocked sized atomic clocks and highly secure space communication.
AngelTech Live III: Join us on 12 April 2021!
AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST)
and will feature online
versions of the market-leading physical events: CS International
and PIC International
PLUS a brand new Silicon Semiconductor International
Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.
2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.
We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.
We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.
Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.
Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.
So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
