Preparing matrix product states via fusion: constraints and extensions
Efficient preparation of many-body quantum states is an essential step in several quantum technologies. We introduce new techniques allowing for the constant-depth preparation of states that we prove were inaccessible using conventional methods. Our work therefore unlocks the efficient realization of new phases of matter in today’s quantum hardware.
