A quantum playground for exploring light topology

A quantum device fabricated by Zhejiang University researchers could help to advance the design of quantum computers as it offers topological control over the units that store information within them. The team’s results were published in Science in December 2022.

Since their discovery around 2007, , known as , have been generating a lot of excitement due to their intriguing properties. For example, they are insulating in their interior, but conducting on their surfaces. This property stems from the topological nature of these materials, which makes them robust to deformations, so electrons moving along their surfaces resist any obstacles that might obstruct their flow.

Researchers have started to explore similar topological systems that are based on light rather than electrons—a field known as topological photonics. But so far, most such light-based systems have used classical forms of light rather than quantum ones. The ability to use quantum forms of light would open up many more possibilities and offer an opportunity to explore the quantum topology of light.

‘Counterportation’: Quantum breakthrough paves way for world-first experimental wormhole

One of the first practical applications of the much-hyped but little-used quantum computing technology is now within reach, thanks to a unique approach that sidesteps the major problem of scaling up such prototypes.

The invention, by a University of Bristol physicist, who gave it the name “counterportation,” provides the first-ever practical blueprint for creating in the lab a wormhole that verifiably bridges space, as a probe into the inner workings of the universe.

By deploying a novel computing scheme, revealed in the journal Quantum Science and Technology, which harnesses the basic laws of physics, a small object can be reconstituted across space without any particles crossing. Among other things, it provides a “smoking gun” for the existence of a physical reality underpinning our most accurate description of the world.

Samsung to invest $230 billion to further semiconductor manufacturing

It’s part of a South Korean project to develop one of the largest semiconductor manufacturing hubs in the world.

An investment of $230 billion is expected to be made in the next two decades by Samsung to further semiconductor manufacturing.

The mega cluster, which will feature five new semiconductor plants built by Samsung, will be set in the Gyeonggi Province and is expected to be completed by 2042.

The investment will be a part of a South Korean project to develop one of the largest semiconductor manufacturing hubs in the world, near its capital city of Seoul. Samsung leads in the production of memory chips, smartphones, and TVs in the world.

High-performance photon detectors to combat spies in the quantum computing age

How can we combat data theft, which is a real issue for society? Quantum physics has the solution. Its theories make it possible to encode information (a qubit) in single particles of light (a photon) and to circulate them in an optical fiber in a highly secure way. However, the widespread use of this telecommunications technology is hampered in particular by the performance of the single-photon detectors.

A team from the University of Geneva (UNIGE), together with the company ID Quantique, has succeeded in increasing their speed by a factor of twenty. This innovation, published in the journal Nature Photonics, makes it possible to achieve unprecedented performances in quantum .

Buying a train ticket, booking a taxi, getting a meal delivered: these are all transactions carried out daily via . These are based on payment systems involving an exchange of secret information between the user and the bank. To do this, the bank generates a , which is transmitted to their customer, and a private key, which it keeps secret. With the public key, the user can modify the information, make it unreadable and send it to the bank. With the private key, the bank can decipher it.

DNA synthesis technologies to close the gene writing gap

NPL, in collaboration with London Biofoundry and BiologIC Technologies Ltd, have released an analysis on existing and emerging DNA Synthesis technologies in Nature Reviews Chemistry, featuring the work on the front cover.

The study, which was initiated by DSTL, set out to understand the development trajectory of DNA Synthesis as a major industry drive for the UK economy over the next 10 years. The demand for synthetic DNA is growing exponentially. However, our ability to make, or write, DNA lags behind our ability to sequence, or read, it. The study reviewed existing and emerging DNA synthesis technologies developed to close this gene writing gap.

DNA or genes provide a universal tool to engineer and manipulate living systems. Recent progress in DNA synthesis has brought up limitless possibilities in a variety of industry sectors. Engineering biology, therapy and diagnostics, , defense and nanotechnology are all set for unprecedented breakthroughs if DNA can be provided at scale and low cost.

Brain Cells Inspire New Computer Components

Summary: Researchers have developed a more powerful and energy-efficient memristor, based on the structure of the human brain, that combines data storage and processing. The new technology, made from nanocrystals of halogenated perovskite, is not yet ready for use as it is difficult to integrate with existing computer chips, but it has the potential for parallel processing of large amounts of data.

Inspired by the brain’s energy efficiency, copying its structure to create more powerful computers, a team of researchers from Politecnico di Milano, Empa and ETH Zurich has developed a memristor that is more powerful and easier to produce than its predecessors: the results have been published in Science Advances.

Sizes of Black Holes: How Big is a Black Hole?

Year 2014 face_with_colon_three If black holes have infinitely small sizes and infinitely density this also means that string theory would also solve the infinitely small problem because now we know that infinitely small sizes exist and if that exists then so does infinite energy from super string essentially filling out the rest of the mystery of the God equation. This means that computers could be infinitely small aswell saving a ton of space aswell.

If you’ve wondered how big is a black hole? then you’ve come to the right place! Learn about the sizes of black holes and the multi-layered answer.
