The latest experiment with photonic entanglement, conducted by Polish physicists working in the consortium National Laboratory for Quantum Technologies, may be of vital importance to make quantum cryptography a more widespread technology. It has been demonstrated that secret communication based on quantum phenomena, which guarantees unconditional security against eavesdropping, can be also realized using sources of quantum entanglement considered until now to be too corrupt.

What was the Big Bang and what happened before it? Scientists from the Faculty of Physics, University of Warsaw have attempted to answer the question. Within the framework of loop quantum gravity they have put forward a new theoretical model, which might prove useful for validating hypotheses about events prior to the Big Bang. This genuinely groundbreaking achievement is one of the few models describing the full Einstein's theory and not merely its greatly simplified version.
