Bosonic quantum error-correcting codes with finite stellar rank
Rui Wang, Adithi Udupa, Timo Hillmann +3
Bosonic quantum error correction (QEC) relies on non-Gaussian bosonic encodings whose preparation cost is a central practical constraint. In this work, we use stellar rank as a res…

Bosonic quantum computing with near-term devices and beyond
Timo Hillmann
(Abridged.) This thesis investigates scalable fault-tolerant quantum computation through the development of bosonic quantum codes, quantum LDPC codes, and decoding protocols that c…

Performance of rotation-symmetric bosonic codes in the presence of random telegraph noise
Adithi Udupa, Timo Hillmann, Rabsan Galib Ahmed +2
Decoherence in quantum devices, such as qubits and resonators, is often caused by bistable fluctuators modeled as random telegraph noise (RTN), leading to significant dephasing. We…
