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…
Phase Estimation of Coherent States with a Noiseless Linear Amplifier
Syed Assad, Mark Bradshaw, Ping Koy Lam
Amplification of quantum states is inevitably accompanied with the introduction of noise at the output. For protocols that are probabilistic with heralded success, noiseless linear…
Maximizing device-independent randomness from a Bell experiment by optimizing the measurement settings
Syed M Assad, Oliver Thearle, Ping Koy Lam
The rates at which a user can generate device-independent quantum random numbers from a Bell-type experiment depend on the measurements that he performs. By numerically optimising…
