A team of chemists, engineers, material scientists and physicists from Princeton University, Rutgers University and the University of Regensburg has developed a chemical exfoliation technique to produce single-molecule-thick tungsten disulfide ink. The group describes their technique in a paper published in the journal Science Advances.

As research continues into the creation of truly useful quantum computers, scientists continue to search for new materials that could support such machines. In this new effort, the research team looked into finding ways to print very cold circuits inside quantum computers using superconducting ink.

The new method involved a material consisting of layers of disulfide and potassium. The researchers exfoliated the material by dunking it into a sulfuric acid solution. This dissolved the potassium and left behind single-molecule layers of tungsten disulfide. The final step involved rinsing the acid and remnants in it, leaving the layers of tungsten suspended in a tub of water. In this state, the researchers found that the layers of tungsten disulfide could be used as a form of ink that could be printed onto various types of surfaces, such as plastic, silicon or glass. This left a one-molecule-thick coating on the material.

Researchers have succeeded in creating an efficient quantum-mechanical light-matter interface using a microscopic cavity. Within this cavity, a single photon is emitted and absorbed up to 10 times by an artificial atom. This opens up new prospects for quantum technology, report physicists at the University of Basel and Ruhr-University Bochum in the journal Nature.

Quantum physics describes photons as light particles. Achieving an interaction between a and a is a huge challenge due to the tiny size of the atom. However, sending the past the atom several times by means of mirrors significantly increases the probability of an interaction.

In order to generate photons, the researchers use artificial atoms, known as . These semiconductor structures consist of an accumulation of tens of thousands of atoms, but behave much like a single atom: when they are optically excited, their energy state changes and they emit a photon. “However, they have the technological advantage that they can be embedded in a ,” says Dr. Daniel Najer, who conducted the experiment at the Department of Physics at the University of Basel.

One of the best ways to learn about any historical period is by conversing with the people who lived through it. Speaking with people from the distant past is very one-sided, as they are typically dead and have stopped listening long ago. However, they speak volumes if you have the patience to listen, or rather, read what they say in letters, diaries and primitive post-it notes with no sticky back sides.

An international group of computer scientists from Italy, the U.K. and Pakistan have teamed up to resurrect the dead from writings that have been degraded by time by developing a computer-assisted method to virtually return documents to a more legible and decipherable condition. In their research paper, “Restoration and content analysis of ancient manuscripts via color space based segmentation,” published in the journal PLOS ONE, the team details their digital restoration technique’s method and experimental results.

We get a sense of ancient civilizations from their writings, both trivial and profound. The Sumerian cuneiform writing on reveals 4,000-year-old merchant transactions, geometric calculations, and poetry detailing the fall of a great city. Had they been written on paper and not in clay we would likely not have them today.

Researchers have discovered a way to “translate” quantum information between different kinds of quantum technologies, with significant implications for quantum computing, communication, and networking.

The research was published in the journal Nature on Wednesday. It represents a new way to convert from the format used by quantum computers to the format needed for quantum communication.

Photons—particles of light—are essential for , but different technologies use them at different frequencies. For example, some of the most common technology is based on , such as those used by tech giants Google and IBM; these qubits store quantum information in that move at microwave frequencies.

The researchers observed it stimulated light emission, which Einstein predicted in 1916, in single photons for the first time.

A team of researchers from the University of Basel and the University of Sydney accomplished a groundbreaking feat by demonstrating the capability to manipulate and identify small numbers of interacting packets of light energy or photons with high correlation for the first time.

The achievement, published in Nature Physics, marks a significant milestone in developing quantum technologies. The researchers observed it stimulated light emission, which Einstein predicted in 1916, in single photons for the first time.
