Quantifying the imaginarity of quantum states via Tsallis relative entropy
Jianwei Xu
It is a fundamental question that why quantum mechanics uses complex numbers instead of only real numbers. To address this topic, recently, a rigorous resource theory for the imagi…

Imaginarity of Gaussian states
Jianwei Xu
It has been a long-standing debate that why quantum mechanics uses complex numbers but not only real numbers. To address this topic, in recent years, the imaginarity theory has bee…

Quantifying the phase of quantum states
Jianwei Xu
Phase is a basic ingredient for quantum states since quantum mechanics uses complex numbers to describe quantum states. In this letter, we introduce a rigorous framework to quantif…
