In a new study published April 23 in the journal Nature Physics, Yale researchers 'pitch' a qubit -- a tiny bit of quantum data -- from one physical point in a microwave cavity to a separate point in a different cavity. It is the first time an end-to-end quantum transmission has been done on demand and represents the first of two Yale experiments involving 'pitch-and-catch' technologies that will be published this year.

Physicists at the University of Warwick have published new research in the journal Science April 19, 2018, (via the Journal's First Release pages) that could literally squeeze more power out of solar cells by physically deforming each of the crystals in the semiconductors used by photovoltaic cells.

Collaborative research team of Prof. Jun Takeda and Associate Prof. Ikufumi Katayama in the laboratory of Yokohama National University (YNU) and Nippon Telegraph and Telephone (NTT) successfully observed petahertz (PHz: 1015 of a hertz) electron oscillation. The periodic electron oscillations of 667-383 attoseconds (as: 10-18 of a second) is the fastest that has ever been measured in the direct time-dependent spectroscopy in solid-state material.

A Japanese research team developed a robot that can identify, collect, and manipulate two-dimensional nanocrystals. The robot stacked nanocrystals to form the most complex van der Waals heterostructure produced to date, with much less human intervention than the manual operations previously used to produce van der Waals heterostructures. This robot allows unprecedented access to van der Waals heterostructures, which are attractive for use in advanced electronics.

An innovative chemical reactor for depositing semiconductors at very high temperatures draws on the strength of Saudi Arabia's chemical industry.

A quantum simulation of topological phases of matter at finite temperature has be realized for the first time by a group of researchers from Universidad Complutense, IBM, ETH Zurich, MIT and Harvard University. These findings open the door to unexpected applications in robust quantum technologies against thermal fluctuations such as quantum computers or memories.

Scientists developed a versatile modification method of graphene without destroying it, which can build strong covalent bonds with polymers. Conductive materials obtained through such method are promising for the development of flexible organic electronics.

A clever combination of novel technologies enables us to study promising materials for the electronics of tomorrow. Using short laser pulses, a research team led by Misha Ivanov of the Max Born Institute in Berlin together with scientists from the Russian Quantum Center in Moscow have now shed light on the extremely rapid processes taking place within novel materials. Their results have appeared in the prestigious journal "Nature Photonics".

Researchers at Aalto University, Finland are the first to create a Bose-Einstein condensate of light coupled with metal electrons, so-called surface plasmon polaritons.
