Abstract given by the source: Quantum computers hold the promise of quantum speed-up, i.e. of solving computational problems faster than normal computers. Applications range from quantum chemistry to the design of new materials. Bosonic systems, where information is encoded in bosonic fields, allow for increased scalability of quantum computers, as well as for long-lived information encoding, as compared to the use of two-level systems, or “qubits". However, interaction with the environment causes noise, affecting the state in a computation, and hindering the possibility of achieving quantum speed-up. In particular, it remains a challenge to distill reliable bosonic resource states, necessary for quantum speed-up, starting from multiple noisy copies. In DAIQUIRI, I will provide reliable protocols for the distillation of quantum information in bosonic quantum processors. To do so, I will use techniques inspired by qubit-based quantum computation. Then, I will characterise which bosonic states can be converted into resource states by using the framework of resource theory. The results of this project will impact the design of bosonic quantum computing architectures, as well as solve the long-standing theoretical problem of bosonic resource state distillation. The research will be carried at Chalmers, within a project duration of 48 months.
