Quantum Information Science

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
