Throughout the densely-populated country of Bangladesh, a lack of access to clean drinking water is responsible for a variety of debilitating and often-lethal infections. Soon, however, residents could filter virtually all harmful microbes out of their water, using paper derived from algae.
Researchers from the Austrian Academy of Sciences and the University of Vienna have experimentally demonstrated what was previously only a theoretical possibility. Together with quantum physicists from the University of Science and Technology of China, they have succeeded in teleporting complex high-dimensional quantum states. The research teams report this international first in the journal “Physical Review Letters”.
In their study, the researchers teleported the quantum state of one photon (light particle) to another distant one. Previously, only two-level states (“qubits”) had been transmitted, i.e., information with values “0” or “1”. However, the scientists succeeded in teleporting a three-level state, a so-called “qutrit”. In quantum physics, unlike in classical computer science, “0” and “1” are not an ‘either/or’ – both simultaneously, or anything in between, is also possible. The Austrian-Chinese team has now demonstrated this in practice with a third possibility “2”.
Novel experimental method.
A team of physicists claims to have discovered a new state of matter — a breakthrough that could vastly improve traditional as well as quantum computing.
The new state, called “topological superconductivity,” could help to increase storage capabilities in electronic devices and enhance quantum computing.
RELATED: ‘QUTRIT’ EXPERIMENTS SHOW PROGRESS IN QUANTUM TELEPORTATION
By Leah Crane
Some ideas about the quantum world appear to suggest there are many versions of you spread out across many parallel universes. Now, two scientists have formulated a proof that attempts to show this is really true.
The proof involves a fundamental construct in quantum mechanics called Bell’s theorem. This theorem deals with situations where particles interact with each other, become entangled, and then go their separate ways. It is what’s called a “no-go theorem”, one designed to show that some assumption about how the world works is not true.
For the first time, Chinese scientists have demonstrated the experiment of transferring quantum information in a 3D state.
Limited in a two-level state for a long time, the study paves the way to teleporting the complete quantum state of a particle, according to an article in American Physical Society a top peer-review journal.
According to Pan Jianwei, coauthor of the study known as the “father of quantum” in China, quantum teleportation is a new communication method to transfer quantum information – a particle’s quantum state in the micro-world.
The size of a cell is determined by a combination of synthesis, self-assembly, incoming matter and the balance of mechanical forces. Such processes operate at the single-cell level, but they are deeply interconnected with cell-cycle progression, resulting in a stable average cell size at the population level. Here, we examine this phenomenon by reviewing the physics of growth processes that operate at vastly different timescales, but result in the controlled production of daughter cells that are close copies of their mothers. We first review the regulatory mechanisms of size at short timescales, focusing on the contribution of fundamental physical forces. We then discuss the multiple relevant regulation processes operating on the timescale of the cell cycle. Finally, we look at how these processes interact: one of the most important challenges to date involves bridging the gap between timescales, connecting the physics of cell growth and the biology of cell-cycle progression.
Robots from all over the world are about to go on a subterranean adventure, competing against each other in mining tunnels to determine which ones can best navigate and find objects underground and do so autonomously.
The Defense Advanced Research Projects Agency (DARPA) is hosting the Subterranean Challenge Systems Competition on Aug. 15–22 in Pittsburgh as a way to develop technology for the military and first responders to map and search subterranean areas.
Metallicus, the startup behind the peer-to-peer payments platform Metal Pay, received an undisclosed angel investment from the youngest bitcoin millionaire, Erik Finman.
In partnership with Metal Pay CEO Marshall Hayner, the two look to develop the first “all-in-one” cryptocurrency banking platform, which includes a 17 digital asset exchange, a digital bank and a payments application with social features similar to Venmo.
Founded in September, Metal Pay has processed approximately $11 million in total payments from nearly 130,000 registered users across 38 states. On a monthly basis, the company processes $1 million in crypto or fiat for around 30,000 active users, according to Hayner.
