Am 13. Oktober 2025 um 14:15 Uhr findet das nächste Physikalische Kolloquium zum Thema "Does noise help a (quantum) search?" im Röntgen-Hörsaal des Physikalischen Instituts und online via Zoom statt.
Efficient retrieval of information from a database is a core operation in our digital society. Quantum physics holds the promise for a definite speedup with respect to existing classical search algorithms. Achieving such speedup, however, requires an outstanding degree of control of the quantum dynamics of systems of large size. This involves suppressing and correcting errors caused by the inevitable action of the external environment. In the life sciences, search strategies are optimised to perform in dynamically changing environments. Adaptability is essential for successfully retrieving information and resources. In this talk, we will discuss these contrasting paradigms and analyse the circumstances in which an external environment could enhance the efficiency of, or even accelerate, a quantum search.
