Verifying the security of a continuous variable quantum communication protocol via quantum metrology
Lorcan O. Conlon, Biveen Shajilal, Angus Walsh +4
Quantum mechanics offers the possibility of unconditionally secure communication between multiple remote parties. Security proofs for such protocols typically rely on bounding the…
Testing the postulates of quantum mechanics with coherent states of light and homodyne detection
Lorcan O. Conlon, Angus Walsh, Yuhan Hua +5
Quantum mechanics has withstood every experimental test thus far. However, it relies on ad-hoc postulates which require experimental verification. Over the past decade there has be…
Multiparameter estimation with two qubit probes in noisy channels
Lorcan. O. Conlon, Ping Koy Lam, Syed. M. Assad
This work compares the performance of single and two qubit probes for estimating several phase rotations simultaneously under the action of different noisy channels. We compute the…
On the equivalence between squeezing and entanglement potential for two-mode Gaussian states
Bohan Li, Aritra Das, Spyros Tserkis +3
The maximum amount of entanglement achievable under passive transformations by continuous-variable states is called the entanglement potential. Recent work has demonstrated that th…
Quantifying total correlations in quantum systems through the Pearson correlation coefficient
Spyros Tserkis, Syed M. Assad, Ping Koy Lam +1
Conventionally the total correlations within a quantum system are quantified through distance-based expressions such as the relative entropy or the square-norm. Those expressions i…
Quantum-optimal information encoding using noisy passive linear optics
Andrew Tanggara, Ranjith Nair, Syed Assad +5
The amount of information that a noisy channel can transmit has been one of the primary subjects of interest in information theory. In this work we consider a practically-motivated…
