Zeno and Anti-Zeno Effects in Dark-State Dynamics Under Thermal Dephasing: A Numerical Study
Ran Chen, Jiangchuan You, Alexey Vladimirovich Kulagin +2
The quantum Zeno and anti-Zeno effects describe how frequent measurements can either suppress or accelerate quantum dynamics. While extensively studied in various platforms, their…
Beyond real: Investigating the role of complex numbers in self-testing
Ranyiliu Chen, Laura Mančinska, Jurij Volčič
We investigate complex self-testing, a generalization of standard self-testing that accounts for quantum strategies whose statistics is indistinguishable from their complex conjuga…
Maximal device-independent randomness in every dimension
Máté Farkas, Jurij Volčič, Sigurd A. L. Storgaard +2
Random numbers are used in a wide range of sciences. In many applications, generating unpredictable private random numbers is indispensable. Device-independent quantum random numbe…
A mathematical foundation for self-testing: Lifting common assumptions
Pedro Baptista, Ranyiliu Chen, Jędrzej Kaniewski +4
In this work we study the phenomenon of self-testing from the first principles, aiming to place this versatile concept on a rigorous mathematical footing. Self-testing allows a cla…
