Bias-Preserving Gates and Quantum Error Correction With Dual-Rail Cat Codes
Debjyoti Biswas, Nikhil Sharma, Alberto Salvador +4
Scalable fault-tolerant quantum computation requires quantum error-correcting codes that simultaneously support universal logical operations, suppress hardware-specific noise, and…
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…
Error Mitigation in Bosonic Systems via Virtual Distillation
Leonardo Finocchiaro, Marco Robbio, Diogo Gomes +5
Virtual distillation is a promising error-mitigation technique that exploits multiple copies of a noisy quantum state to estimate observables as if measured on a purified state. Al…
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…
