Integrated photonic platform with high-speed entanglement generation and witnessing
Gong Zhang, Chao Wang, Koon Tong Goh +10
High-speed generation and efficient entanglement detection on a photonic chip are essential for quantum information applications but hard to achieve due to common photonic chips' m…
Provably-secure quantum randomness expansion with uncharacterised homodyne detection
Chao Wang, Ignatius William Primaatmaja, Hong Jie Ng +5
Quantum random number generators (QRNGs) are able to generate numbers that are certifiably random, even to an agent who holds some side-information. Such systems typically require…
Discrete-variable quantum key distribution with homodyne detection
Ignatius William Primaatmaja, Cassey Crystania Liang, Gong Zhang +3
Most quantum key distribution (QKD) protocols can be classified as either a discrete-variable (DV) protocol or continuous-variable (CV) protocol, based on how classical information…
Securing practical quantum communication systems with optical power limiters
Gong Zhang, Ignatius William Primaatmaja, Jing Yan Haw +3
Controlling the energy of unauthorized light signals in a quantum cryptosystem is an essential criterion for implementation security. Here, we propose a passive optical power limit…
Machine Learning Cryptanalysis of a Quantum Random Number Generator
Nhan Duy Truong, Jing Yan Haw, Syed Muhamad Assad +2
Random number generators (RNGs) that are crucial for cryptographic applications have been the subject of adversarial attacks. These attacks exploit environmental information to pre…
Real-Time Source Independent Quantum Random Number Generator with Squeezed States
Thibault Michel, Jing Yan Haw, Davide G. Marangon +5
Random numbers are a fundamental ingredient for many applications including simulation, modelling and cryptography. Sound random numbers should be independent and uniformly distrib…
Entanglement properties of a measurement-based entanglement distillation experiment
Hao Jeng, Spyros Tserkis, Jing Yan Haw +5
Measures of entanglement can be employed for the analysis of numerous quantum information protocols. Due to computational convenience, logarithmic negativity is often the choice in…
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…
Overarching framework between Gaussian quantum discord and Gaussian quantum illumination
Mark Bradshaw, Syed M. Assad, Jing Yan Haw +3
We cast the problem of illuminating an object in a noisy environment into a communication protocol. A probe is sent into the environment, and the presence or absence of the object…
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…
Bridging the gap between the Jaynes-Cummings and Rabi models using an intermediate rotating wave approximation
Yimin Wang, Jing Yan Haw
We present a novel approach called the intermediate rotating wave approximation (IRWA), which employs a time-averaging method to encapsulate the dynamics of light-matter interactio…
Replicating the benefits of closed timelike curves without breaking causality
Xiao Yuan, Syed M. Assad, Jayne Thompson +6
In general relativity, closed timelike curves can break causality with remarkable and unsettling consequences. At the classical level, they induce causal paradoxes disturbing enoug…
Maximization of Extractable Randomness in a Quantum Random-Number Generator
J. Y. Haw, S. M. Assad, A. M. Lance +4
The generation of random numbers via quantum processes is an efficient and reliable method to obtain true indeterministic random numbers that are of vital importance to cryptograph…
Measurement-Based Noiseless Linear Amplification for Quantum Communication
Helen M. Chrzanowski, Nathan Walk, Syed M. Assad +5
Entanglement distillation is an indispensable ingredient in extended quantum communication networks. Distillation protocols are necessarily non-deterministic and require advanced e…
Experimental demonstration of Gaussian protocols for one-sided device-independent quantum key distribution
Nathan Walk, Sara Hosseni, Jiao Geng +9
Nonlocal correlations, a longstanding foundational topic in quantum information, have recently found application as a resource for cryptographic tasks where not all devices are tru…
Experimental Verification of Quantum Discord in Continuous-Variable States
S. Hosseini, S. Rahimi-Keshari, J. Y. Haw +6
We introduce a simple and efficient technique to verify quantum discord in unknown Gaussian states and a certain class of non-Gaussian states. We show that any separation in the pe…
Parity Measurement in Ultrastrong Coupling Regime
Jing Yan Haw, Yimin Wang, Valerio Scarani
The measurement of the parity of two qubits is a primitive of quantum computing that allows creating deterministic entanglement. In the field of circuit quantum electrodynamics, a…
