Enhancing Long-distance Continuous-variable Quantum-key-distribution with an Error-correcting Relay
S. Nibedita Swain, Ryan J. Marshman, Josephine Dias +2
Noiseless linear amplifiers (NLAs) serve as an effective means to enable long-distance continuous-variable (CV) quantum key distribution (QKD), even under realistic conditions with…
Noise-reduction of multimode Gaussian Boson Sampling circuits via Unitary Averaging
S. Nibedita Swain, Ryan J. Marshman, Alexander S. Solntsev +1
We improve Gaussian Boson Sampling (GBS) circuits by integrating the unitary averaging (UA) protocol, previously demonstrated to protect unknown Gaussian states from phase errors […
Noise Transfer Approach to GKP Quantum Circuits
Timothy C Ralph, Matthew Winnel, S Nibedita Swain +1
The choice between the Schroedinger and Heisenberg pictures can significantly impact the computational resources needed to solve a problem, even though they are equivalent formulat…
Improving Continuous-variable Quantum Channels with Unitary Averaging
S. Nibedita Swain, Ryan J. Marshman, Peter P. Rohde +3
A significant hurdle for quantum information and processing using bosonic systems is stochastic phase errors which occur as the photons propagate through a channel. These errors wi…
