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

Photon catalysis is an intriguing quantum mechanical operation during which no photon is
added to or subtracted from the relevant optical system. However, we prove that photon …

Besides quantum entanglement and steering, quantum coherence has also been identified
as a useful quantum resource in quantum information. It is important to investigate the …

We study the dynamics and redistribution of entanglement and coherence in three time-
dependent coupled harmonic oscillators. We resolve the Schrödinger equation by using …

As one of the most remarkable features of quantum mechanics, quantum coherence is
regarded as an invaluable quantum resource in quantum information. Using the optical fiber …

Coherence is a basic feature for quantum states. Instead of quantum states, in this work, we
establish a resource theory for quantifying the coherence of Gaussian channels. To do this …

Quantum coherence plays an important role in quantum information processing. In this
Letter, we experimentally demonstrate the conversion of local and correlated Gaussian …

Orbital angular momentum (OAM) multiplexed entangled state is an important quantum
resource for high dimensional quantum information processing. In this paper, we …

Singularity or negativity of Glauber P-function is a widespread notion of nonclassicality, with
important implications in quantum optics and with the character of an irreducible resource …
