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…
Exact and approximate conditions of tabletop reversibility: when is Petz recovery cost-free?
Minjeong Song, Hyukjoon Kwon, Valerio Scarani
Channels that describe open quantum dynamics are inherently irreversible: it is impossible to undo their effect completely, but one can study partial recovery of the…
Testing nonstabilizerness only with stabilizer states
Hyukjoon Kwon
The stabilizer formalism plays a central role in quantum information processing and quantum computing. Since stabilizer states and operations can be efficiently simulated classical…
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…
Probing Quantum States over Spacetime Through Interferometry
Seok Hyung Lie, Hyukjoon Kwon
Establishing a notion of the quantum state that applies consistently across space and time could be a crucial step toward formulating a relativistic quantum theory. We give an oper…
The thermodynamic uncertainty relation of a quantum-mechanically coupled two-qubit system
Kwang Hyun Cho, Hyukjoon Kwon, Changbong Hyeon
The minimal bound of the thermodynamic uncertainty relation (TUR) is modulated from that of the classical counterpart () when a quantumness is present in t…
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…
Causal Asymmetry of Classical and Quantum Autonomous Agents
Spiros Kechrimparis, Mile Gu, Hyukjoon Kwon
Why is it that a ticking clock typically becomes less accurate when subject to outside noise but rarely the reverse? Here, we formalize this phenomenon by introducing process causa…
