As the size of modern technology shrinks down to the nanoscale, weird quantum effects—such as quantum tunneling, superposition, and entanglement—become prominent. This opens the door to a new era of quantum technologies, where quantum effects can be exploited. Many everyday technologies make use of feedback control routinely; an important example is the pacemaker, which must monitor the user’s heartbeat and apply electrical signals to control it, only when needed. But physicists do not yet have an equivalent understanding of feedback control at the quantum level. Now, physicists have developed a “master equation” that will help engineers understand feedback at the quantum scale. Their results are published in the journal Physical Review Letters.

“It is vital to investigate how feedback control can be used in quantum technologies in order to develop efficient and fast methods for controlling quantum systems, so that they can be steered in real time and with high precision,” says co-author Björn Annby-Andersson, a quantum physicist at Lund University, in Sweden.

An example of a crucial feedback-control process in quantum computing is quantum error correction. A quantum computer encodes information on physical qubits, which could be photons of light, or atoms, for instance. But the quantum properties of the qubits are fragile, so it is likely that the encoded information will be lost if the qubits are disturbed by vibrations or fluctuating electromagnetic fields. That means that physicists need to be able to detect and correct such errors, for instance by using feedback control. This error correction can be implemented by measuring the state of the qubits and, if a deviation from what is expected is detected, applying feedback to correct it.

When asked to write the numbers from one to ten in a sequence, how do you order them? Horizontally? Vertically? Left to right? Top to bottom? Would you place them randomly?

It has been often been assumed, and taught in schools in Western countries, that the “correct” ordering of numbers is from left to right (1, 2, 3, 4…) rather than right to left (10, 9, 8, 7…). The ordering of numbers along a horizontal dimension is known as a “mental number line” and describes an important way we represent number and quantity in space.

Studies show humans prefer to position larger numbers to the right and smaller numbers to the left. People are usually faster and more accurate at comparing numbers when larger ones are to the right and smaller ones are to the left, and people with brain damage that disrupts their spatial processing also show similar disruptions in number processing.

Scientists have discovered a beautiful ocean world that looks like it was ripped out of the Star Wars prequels. The exoplanet TOI-1452 b was discovered just 100 light-years from Earth. A new paper on the discovery says that the entire planet is covered by a thick layer of water and that it’s located far enough from its star to possibly support life.

The ocean world was discovered by a team of researchers at the Université de Montréal. Charles Cadieux, the team leader, announced the discovery this week. Cadieux is also a member of the Institute for Research on Exoplanets (iREx).

Findings from a machine learning study suggest that some of the speech differences associated with autism are consistent across languages, while others are language-specific. The study, published in the journal PLOS One, was conducted among separate samples of English speakers and Cantonese speakers.

Autism spectrum disorder (ASD) is often accompanied by differences in speech prosody. Speech prosody describes aspects of speech, like rhythm and intonation, that help us express emotions and convey meaning with our words. Atypical speech prosody can interfere with a person’s communication and social abilities, for example, by causing a person to misunderstand others or be misunderstood themselves. The reason these speech differences commonly present among autistic people is not fully understood.

Study author Joseph C. Y. Lau and his team wanted to shed light on this topic by studying prosodic features associated with autism across two typologically distinct languages.

This is just one of many military advancements the nation has made against its arch-rival.

Back in July, South Korea undertook a 33-minute flight of its homegrown KF-21 fighter jet for the first time flaunting its military might and perhaps sending a message to North Korea.

South Korea is pursuing stealth drones that could take out North Korean air defenses as part of a “manned-unmanned teaming system.”

This finding “proved” the significance of chromosomal rearrangement, a crucial evolutionary indicator of the emergence of a new species.

Researchers from the Chinese Academy of Sciences (CAS) claim to have found a novel technique for programmable chromosome fusion successfully producing mice with genetic changes “that occur on a million-year evolutionary scale” in the laboratory.

The findings could shed light on how chromosome rearrangements—the tidy packages of organized genes provided in equal numbers by each parent, which align and trade or blend traits to produce offspring—influence evolution, reported Phys.org on Thursday.

The oldest radio galaxy yet discovered is hidden in a cluster.

Astronomers claim to have found the oldest fossil radio galaxy yet discovered, hiding in a cluster. The brightest galaxy in the cluster erupted as a result of supermassive black hole activity, blowing massive bubbles of radio light into space, according to a report published by ScienceAlert.

“These newly discovered bubbles — known as radio lobes, or a radio galaxy — are the oldest of their kind we’ve ever seen,” claimed the astronomers’ team led by Surajit Paul and Savitribai Phule from Pune University in India.

Are you curious?

Imagine two towns on two opposite sides of a mountain. People from these towns would probably have to travel all the way around the mountain to visit one another. But, if they wanted to get there faster, they could dig a tunnel straight through the mountain to create a shortcut. That’s the idea behind a wormhole.

A wormhole is like a tunnel between two distant points in our universe that cuts the travel time from one point to the other. Instead of traveling for many millions of years from one galaxy to another, under the right conditions, one could theoretically use a wormhole to cut the travel time down to hours or minutes.
