Generating photons for communication in a quantum computing system

MIT researchers using superconducting quantum bits connected to a microwave transmission line have shown how the qubits can generate on demand the photons, or particles of light, necessary for communication between quantum processors.

An electrical trigger fires single, identical photons

Secure telecommunications networks and rapid information processing make much of modern life possible. To provide more secure, faster, and higher-performance information sharing than is currently possible, scientists and engineers are designing next-generation devices that harness the rules of quantum physics. Those designs rely on single photons to encode and transmit information across quantum networks and between quantum chips. However, tools for generating single photons do not yet offer the precision and stability required for quantum information technology.

Nanoscale machines convert light into work

Researchers have developed a tiny new machine that converts laser light into work. These optically powered machines self-assemble and could be used for nanoscale manipulation of tiny cargo for applications such as nanofluidics and particle sorting.

Researchers design the world's fastest ultraviolet camera

The team of Professor Jinyang Liang, a specialist in ultrafast imaging at the Institut national de la recherche scientifique (INRS), in collaboration with an international team of researchers, has developed the fastest camera in the world capable of recording photons in the ultraviolet (UV) range in real time. This original research is featured on the front cover of the 10th issue of the journal Laser & Photonics Reviews.

Researchers at UNSW Sydney have demonstrated the lowest noise level on record for a semiconductor quantum bit, or qubit. The research was published in Advanced Materials.

Mind and space bending physics on a convenient chip

Thanks to Einstein, we know that our three-dimensional space is warped and curved. And in curved space, normal ideas of geometry and straight lines break down, creating a chance to explore an unfamiliar landscape governed by new rules. But studying how physics plays out in a curved space is challenging: Just like in real estate, location is everything.

Astronomy and Space news

The research, just published in the Astrophysical Journal, was done using the Neutron star Interior Composition Explorer (NICER), an X-ray instrument aboard the International Space Station.

New measurements of the solar spectrum verify Einstein's theory of General Relativity

An international team of researchers led by the Instituto de Astrofísica de Canarias (IAC) has measured, with unprecedented accuracy, the gravitational redshift of the Sun, a change in frequency of the lines in the solar spectrum which is produced when the light escapes from the gravitational field of the Sun on its way to Earth. This work, which verifies one of the predictions of Einstein's General Relativity, is to be published in the journal Astronomy & Astrophysics.

Finding vaporized metal in the air of an exoplanet

WASP-121b is an exoplanet located 850 light years from Earth, orbiting its star in less than two days—a process that takes Earth a year to complete. WASP-121b is very close to its star—about 40 times closer than Earth to the Sun. This close proximity is also the main reason for its immensely high temperature of around 2,500 to 3,000 degrees Celsius. This makes it an ideal object of study to learn more about ultra-hot worlds.

The human heart in space: What can we learn from mathematical modeling

Human spaceflight has been fascinating man for centuries, representing the intangible need to explore the unknown, challenge new frontiers, advance technology and push scientific boundaries further. A key aspect of long-term human spaceflight is the physiological response and consequent microgravity (0G) adaptation, which has all the features of accelerated aging involving almost every body system: muscle atrophy and bone loss, onset of balance and coordination problems, loss of functional capacity of the cardiovascular system.

A home energy management system to achieve optimal control of heat pumps and photovoltaics

Over the past few decades, researchers worldwide have developed a growing amount of systems that can produce renewable energy, such as solar, wind or hydroelectric energy. While some companies and individuals have already started adopting these technologies, a complete transition to more sustainable energy systems is yet to take place. Tools that simplify the implementation and management of renewable energy systems in both industrial and residential settings could ultimately aid this transition.

A very tiny alteration can help deepfakes escape detection

Last month, Sophie Wilmès, the prime minister of Belgium, appeared in an online video to tell her audience that the COVID-19 pandemic was linked to the "exploitation and destruction by humans of our natural environment." Whether or not these two existential crises are connected, the fact is that Wilmès said no such thing. Produced by an organization of climate change activists, the video was actually a deepfake, or a form of fake media created using deep learning. Deepfakes are yet another way to spread misinformation—as if there wasn't enough fake news about the pandemic already.
