We present an algorithm of quantum engineering of large-amplitude $$\ge 5$$ high-fidelity $$\ge 0.99$$ even/odd Schrödinger cat states (SCSs) using a single mode squeezed vacuum (SMSV) state as resource. Set of $$k$$ beam splitters (BSs) with arbitrary transmittance and reflectance coefficients sequentially following each other acts as a hub that redirects a multiphoton state into the measuring modes simultaneously measured by photon number resolving (PNR) detectors. We show that the multiphoton state splitting guarantees significant increase of the success probability of the SCSs generator compared to its implementation in a single PNR detector version and imposes less requirements on ideal PNR detectors.

Cryptocurrency mining is only accessible to those with access to highly discounted energy. The newly-developed low-energy chips will make it possible for everyone to participate in mining profitably.

If you were to ask anyone their feelings about cryptocurrency in 2020, chances are they would respond along the lines of “to the moon”(Crypto investors often use the phrase when they believe that certain cryptocurrencies will rise significantly in price). However, a year later, those sentiments seemed to have jaded. A sense of negativity — FUD (fear, uncertainty, and doubt), as crypto-sympathizers would call it — seemed rife.

A primary reason behind the fading support of the public, besides bad actors flooding the market with ponzi-like schemes and scams, seemed to be massive numbers of energy consumption floated by crypto and blockchain critics. The biggest question was “How is the world supposed to go greener and rely on these energy-hogging, power-hungry technologies?”

The research project was originally based on a new group of viruses that the study authors discovered in the water of the Gossenköllesee in Tyrol, Austria, in 2021.

During a comprehensive study of complex single-celled microbes, scientists from the University of Innsbruck’s Department of Ecology made a groundbreaking discovery. They discovered the DNA of more than 30,000 viruses that were previously unknown, integrated into the microbes’ genome.

The study revealed that some microbes contain a significant proportion of their DNA that is made up of hidden viruses, up to 10 percent.

Critics are not fully convinced though.

Earlier this month, the New York Police Department (NYPD) announced the induction of two robotic dogs into its force, a move that was opposed by rights activists citing surveillance concerns. Now an incident of a garage collapse where a robotic dog was used in search and rescue operations is being hailed by the City Mayor Eric Adams as justification for its use, The New York Times.

The robotic dogs inducted belong to Boston Dynamics, which Interesting Engineering has extensively covered over the years. Their robotic dog, dubbed Spot, has been designed for use in adverse situations and is equipped with abilities and sensors.

People typically think of food as calories, energy and sustenance. However, the latest evidence suggests that food also “talks” to our genome, which is the genetic blueprint that directs the way the body functions down to the cellular level.

This communication between food and genes may affect your health, physiology and longevity. The idea that food delivers important messages to an animal’s genome is the focus of a field known as nutrigenomics. This is a discipline still in its infancy, and many questions remain cloaked in mystery. Yet already, we researchers have learned a great deal about how food components affect the genome.

I am a molecular biologist who researches the interactions among food, genes and brains in the effort to better understand how food messages affect our biology. The efforts of scientists to decipher this transmission of information could one day result in healthier and happier lives for all of us. But until then, has unmasked at least one important fact: Our relationship with food is far more intimate than we ever imagined.
