In some hours, at midnight between Friday and Saturday, ten more countries will join the European Union. The EC-supported Venus Transit 2004 (VT-2004) programme is active in almost all of these, with VT-2004 National Nodes already established the Czech Republic, Hungary, Malta, Poland, Slovenia and Slovakia; more are likely to follow soon. The organisers include the Astronomical Institute of the Academy of Sciences of the Czech Republic and the next VT-2004 meeting will be held near Prague on May 7-9 (see below).
Venus Moves Closer
"Catching up" with the Earth in its orbit (see VT-2004 Animation C), Venus will be placed exactly between the Sun and our planet in the morning of June 8, the day of the extremely rare event, known as a "Venus Transit". Observers in the eastern hemisphere will be able to see Venus as a black spot slowly crossing the solar disk during about 5 1/2 hours.

A new assessment of NASA's record of global temperatures revealed that the agency's estimate of Earth's long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing confidence that past and future research is correctly capturing rising surface temperatures.
The most complete assessment ever of statistical uncertainty within the GISS Surface Temperature Analysis (GISTEMP) data product shows that the annual values...
Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer. The experiments were published in Physical Review Letters and the related theory in Physical Review B.
The spin of an electron is a promising candidate for use as the smallest information unit (qubit) of a quantum computer. Controlling and switching this spin or...

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.
Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...
'Quantum technologies' utilise the unique phenomena of quantum superposition and entanglement to encode and process information, with potentially profound benefits to a wide range of information technologies from communications to sensing and computing.
However a major challenge in developing these technologies is that the quantum phenomena are very fragile, and only a handful of physical systems have been...
