The field of quantum information bloomed two decades ago when scientists realized that quantum physics could be used to transmit and process information in more efficient and secure ways. The development of quantum algorithms and communication protocols, as well as the possibility of implementing them with different systems, has established the field of quantum information as one of the most promising for the 21st century. Apart from the long-term goal of building a quantum computer, the scientific community intensively pursues many other outstanding challenges. In particular, the theory underlying the field of quantum information and dealing with "entanglement" has found intriguing connections with different fields of physics, like condensed matter, quantum gravity, or string theory. Quantum information theory also has strong connections with quantum sensing and metrology, quantum simulation, quantum networks, and quantum dynamics. It also serves as the basis of newly developed tensor-network techniques to describe many-body quantum systems. Furthermore, new applications, protocols, and algorithms are expected to be developed in the near future. Researchers at Harvard and MPQ have pioneered some of those developments, and actively collaborated among themselves and with other scientists in the implementation of the theoretical proposals
