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…
Entanglement distillation rates exceeding the direct transmission bound
Farzad Ghafari, Josephine Dias, L Krister Shalm +4
Entanglement distribution is crucial for quantum communication and cryptography but is hindered by channel loss and decoherence. Noiseless linear amplification (NLA) is a probabili…
Performance of Rotation-Symmetric Bosonic Codes in a Quantum Repeater Network
Pei-Zhe Li, Josephine Dias, William J. Munro +3
Quantum error correction codes based on continuous variables play an important role for the implementation of quantum communication systems. A natural application of such codes occ…
Entanglement generation between distant spins via quasilocal reservoir engineering
Josephine Dias, Christopher W. Wächtler, Kae Nemoto +1
The generation and preservation of entanglement is a central goal in quantum technology. Traditionally, dissipation in quantum systems is thought to be detrimental to entanglement,…
Reservoir-assisted energy migration through multiple spin-domains
Josephine Dias, Christopher W. Wächtler, Victor M. Bastidas +2
The transfer of energy through a network of nodes is fundamental to both how nature and current technology operates. Traditionally we think of the nodes in a network being coupled…
Quantum repeater for continuous variable entanglement distribution
Josephine Dias, Matthew S. Winnel, Nedasadat Hosseinidehaj +1
Quantum repeaters have been proposed as a way of extending the reach of quantum communication. First generation approaches use entanglement swapping to connect entangled links alon…
Distributing entanglement in first generation discrete and continuous variable quantum repeaters
Josephine Dias, Matthew S. Winnel, William J. Munro +2
Quantum repeaters are used to overcome the exponential photon loss scaling that quantum states acquire as they are transmitted over long distances. While repeaters for discrete var…
Quantum enhancement of signal-to-noise ratio with a heralded linear amplifier
Jie Zhao, Josephine Dias, Jing Yan Haw +6
Due to the pervasive nature of decoherence, protection of quantum information during transmission is of critical importance for any quantum network. A linear amplifier that can enh…
Simulation of Gaussian channels via teleportation and error correction of Gaussian states
Spyros Tserkis, Josephine Dias, Timothy C. Ralph
Gaussian channels are the typical way to model the decoherence introduced by the environment in continuous-variable quantum states. It is known that those channels can be simulated…
Quantum error-correction of continuous-variable states with realistic resources
Josephine Dias, Timothy C Ralph
Gaussian noise induced by loss on Gaussian states may be corrected by distributing EPR entanglement through the loss channel, purifying the entanglement using a noiseless linear am…
Quantum Repeaters Using Continuous Variable Teleportation
Josephine Dias, Timothy C Ralph
Quantum optical states are fragile and can become corrupted when passed through a lossy communication channel. Unlike for classical signals, optical amplifiers cannot be used to re…
Surpassing the no-cloning limit with a heralded hybrid linear amplifier for coherent states
Jing Yan Haw, Jie Zhao, Josephine Dias +6
The no-cloning theorem states that an unknown quantum state cannot be cloned exactly and deterministically due to the linearity of quantum mechanics. Associated with this theorem i…
Continuous Variable Quantum Repeaters
Josephine Dias, Tim Ralph
We propose a quantum repeater for continuous variable (CV) quantum optical states. Our repeater relies on an error correction protocol for loss on CV states based on CV teleportati…
