Who has both the Nobel and Ig Nobel Prizes?

The Dutch physicist of Russian origin Andrei Geim received the Nobel Prize in 2010 for experiments that helped to study the properties of graphene. And 10 years earlier, he received the ironic Ig Nobel Prize for an experiment on diamagnetic levitation of frogs. Thus, Game became the first person in the world who owns both the Nobel Prize and the Ig Nobel Prize.

Where did Pinocchio come from?

From the Italian fairy tale by G. Collodi "Pinocchio". Aleksey Nikolaevich Tolstoy (1882/83-1945) rewrote it anew, and already Pinocchio became known to all children and adults as a mischievous wooden boy.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Multicolored photons 25.07.2017

Despite the huge amount of research in the field of quantum computing, universal quantum computers continue to be a purely theoretical concept. Let us remind our readers that the basis of any quantum computer or communication system is quantum bits called qubits. Qubits differ from traditional bits in that, in addition to the two basic states, 1 or 0, they can be in a third state - in a state of superposition, when the value of a qubit is both 1 and 0. This, in turn, allows using one qubit to perform two parallel computing operations.

The connection of individual qubits into a computing system is carried out using the phenomenon of quantum entanglement. At the same time, a system of two qubits is already capable of performing four parallel operations, and a system of three qubits is capable of performing eight. And a system with dozens of qubits is capable of computing much faster than traditional computers.

However, the state of superposition and the phenomenon of quantum entanglement are extremely fragile things that are destroyed at the slightest impact on them from the outside. And scientists from the Institute INRS (Institut national de la recherche scientifique), Canada, have proposed a very interesting and promising alternative to qubits - multidimensional quantum bits (quDit), based on the use of "colorful" photons of light. Moreover, these researchers created a quantum chip on which two quDits were created, with the help of which research was carried out on this new quantum technology.

An optical cavity is located on the surface of the quantum chip, into which two entangled photons of light are launched. Each of the photons can have 10 basic quantum states determined by its wavelength (color) and be in a state of superposition, in which it can be red AND green AND blue AND yellow at the same time. These colors were given conditionally, since infrared photons were used in practice.

Thus, each of the "colorful" photons is capable of being in 100 different states, and a system of two such photons, quDits, is equivalent in performance (the number of parallel operations performed by it) to a system with 12 classical qubits entangled with each other. "For the first time, we have managed to obtain a multidimensional quantum state in a fairly simple way," says Michael Kues, lead researcher. "And our next task will be to use such a multidimensional quantum system to perform practical calculations."
