Quantum to Classical Crossover in Mechanical Systems

Description and aim

In recent years there has been a rapid development in controlling micro- and nano-meter size mechanical systems to the point where quantum physics becomes crucial for understanding the dynamics of such systems. Quantized oscillations of mechanical resonators are now being discussed and have potential applications in the field of quantum information science. Through this development, new tests of fundamental aspects of quantum mechanics, such as superpositions of states and entanglement between systems, have come within reach for macroscopic objects. These new experimental possibilities provide new input to the discussion of how the classical world emerges from the underlying quantum physics. A related question, whether quantum physics is needed to understand properties (beyond those of the chemical reactions and molecular compositions) of biological systems will also be addressed. This workshop will bring together leading experimentalists and theorists in this field of research.
