ICQE 2027 is a scientific conference that brings together researchers, industry representatives, funders, and policymakers working at the frontier where quantum science and technology meet energy applications. This 3rd edition of ICQE explores an emerging vision of nuclear quantum engineering: the idea that nuclear processes may be shaped or controlled through designed materials, fields, and many-body interactions. The conference also features established themes of quantum energy, including quantum batteries and, more broadly, quantum dynamics in chemistry and materials.
