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…
Utility of noiseless linear amplification and attenuation in single-rail discrete-variable quantum communications
Ozlem Erkilic, Aritra Das, Angela A. Baiju +3
Quantum communication offers many applications, with teleportation and superdense coding being two of the most fundamental. In these protocols, pre-shared entanglement enables eith…
Software-enhanced simultaneous quantum-classical communication protocol with Gaussian post-selection
Ozlem Erkilic, Biveen Shajilal, Nicholas Zaunders +1
Simultaneous quantum-classical communication (SQCC) protocols offer a practical approach to continuous-variable quantum key distribution (CV-QKD) by encoding quantum and classical…
Entanglement distribution via satellite: an evaluation of competing protocols assuming realistic free-space optical channels
Nicholas Zaunders, Timothy C. Ralph
A key technical requirement of any future quantum network is the ability to distribute quantum-entangled resources between two spatially separated points at a high rate and high fi…
Stokes Parameters and Dual Classical-Quantum Signaling
Anjali Dhiman, Ziqing Wang, Timothy C. Ralph +2
Catering to emerging satellite-based free-space optical (FSO) communication networks and exploiting polarization encoding via Stokes operators, we propose a novel simultaneous quan…
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 […
Enhanced Simultaneous Quantum-Classical Communications Under Composable Security
Nicholas Zaunders, Ziqing Wang, Robert Malaney +2
Simultaneous quantum-classical communications (SQCC) protocols are a family of continuous-variable quantum key distribution (CV-QKD) protocols which allow for quantum and classical…
General relativistic particle trajectories via quantum mechanical weak values and the Schwarzschild-Alcubierre spacetime
Joshua Foo, Cameron Bellamy, Timothy C. Ralph
We show that the average trajectories of relativistic quantum particles in Schwarzschild spacetime, obtained via quantum mechanical weak measurements of momentum and energy, are eq…
