Exact Incompatibility-Breaking Criterion for Unital Qubit Channels
Yujie Zhang
The paper derives the exact condition under which unital qubit channels make all POVMs jointly measurable, showing that projective measurements set the boundary, and uses this to d…
Cost of Simulating Entanglement in Steering Scenario
Yujie Zhang, Jiaxuan Zhang, Eric Chitambar
Quantum entanglement is a fundamental feature of quantum mechanics, yet certain entangled states that are unsteerable can be classically simulated in steering scenarios, making the…
Temporally localized quantum operations on continuous-wave thermal light
Yunkai Wang, Yujie Zhang, Virginia O. Lorenz
Previous work showed that thermal light with a blackbody spectrum cannot be decomposed into a mixture of independent localized pulses. However, we find that in the weak-source limi…
Astronomical interferometry using continuous variable quantum teleportation
Yunkai Wang, Yujie Zhang, Virginia O. Lorenz
We propose a method to build an astronomical interferometer using continuous variable quantum teleportation to overcome the transmission loss between distant telescopes. The scheme…
