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…
How Quantum Agents Can Change Which Strategies Are More Complex
Spiros Kechrimparis, Nix Barnett, Mile Gu +1
Whether winning blackjack or navigating busy streets, achieving desired outcomes requires agents to execute adaptive strategies, strategies where actions depend contextually on pas…
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…
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…
