Local Gaussian bounds on the non-destructive discrimination of two-mode squeezed states
Mi-Jung So, James Moran, Youngrong Lim +2
Typical measurement setups in quantum systems are destructive, meaning that states are irretrievably altered after measurement. In this work, we analyse non-destructive discriminat…
Probabilistic Channel Distillation via Indefinite Causal Order
Spiros Kechrimparis, James Moran, Hyukjoon Kwon
The quantum switch has been widely studied as a prototypical example of indefinite causal order in quantum information processing. However, the potential advantages of utilising mo…
Near-optimal coherent state discrimination via continuously labelled non-Gaussian measurements
James Moran, Spiros Kechrimparis, Hyukjoon Kwon
Quantum state discrimination plays a central role in quantum information and communication. For the discrimination of optical quantum states, the two most widely adopted measuremen…
Enhancing Quantum State Discrimination with Indefinite Causal Order
Spiros Kechrimparis, James Moran, Athena Karsa +2
The standard quantum state discrimination problem can be understood as a communication scenario involving a sender and a receiver following these three steps: (i) the sender encode…
