A Macroscopic Violation of No Signaling In Time Inequalities? How to test Temporal Entanglement with Behavioral Observables [PDF]
Frontiers in Psychology, 2015 In this paper we applied for the first time the no-signaling in time (NSIT) formalism discussed by Kofler and Brukner to investigate temporal entanglement between binary human behavioral unconscious choices at t1 with binary random outcomes at t2.

Entanglement-enhanced quantum lock-in detection achieving Heisenberg scaling [PDF]
Nature CommunicationsQuantum lock-in detection (QLID) is a powerful technique for extracting weak oscillating signals within noise. While entanglement may enhance measurement precision beyond the standard quantum limit (SQL), its integration with QLID is still an ...

Transitions in Entanglement Complexity in Random Circuits [PDF]
Quantum, 2022 Entanglement is the defining characteristic of quantum mechanics. Bipartite entanglement is characterized by the von Neumann entropy. Entanglement is not just described by a number, however; it is also characterized by its level of complexity.

Quantifying Quantumness of Channels Without Entanglement
PRX Quantum, 2022 Quantum channels breaking entanglement, incompatibility, or nonlocality are defined as such because they are not useful for entanglement-based, one-sided device-independent, or device-independent quantum-information processing, respectively.
