The 2023 conference follows the previous QBIC meetings in Warwick (1999), Lund (2003), Český Krumlov (2011), Bath (2018), and Marseille (2019). QBIC-VI is the third meeting organized since the founding of the Quantum Bioinorganic Chemistry Society. The scientific focus of the conference is on computational inorganic and bioinorganic chemistry, covering theoretical methods, novel applications, and combined computational/experimental approaches.
