The Optica Quantum 2.0 Conference and Exhibition 2023 will be held from 18th June to 22nd June 2023. This conference brings together academics, industry and government scientists, national labs and others working to advance quantum science and technology. Participants will have the opportunity to interact, discover common ground and potentially build collaborations leading to new concepts or development opportunities. Our goal is to promote the development of mature quantum technologies that will allow us to build Quantum 2.0 systems capable of quantum advantage and to look forward to new scientific frontiers beyond the scope of current technologies.
