Thermal vapor quantum battery based on collective atomic spins
Jinyi Li, Juncheng Zheng, Xue Yang +7
Quantum batteries harness non-classical resources, such as quantum coherence and entanglement, to surpass the performance limits of classical energy-storage devices. Here we realiz…
On small perturbations of coherent information
Zhen Wu, Zhihao Ma, James Fullwood
Quantum capacity quantifies the amount of quantum information that can be transmitted by a quantum channel with an arbitrary small probability of error. Mathematically, the quantum…
The spatiotemporal Born rule is quasiprobabilistic
James Fullwood, Zhihao Ma, Zhen Wu
Contrary to general relativity, quantum theory treats space and time in fundamentally different ways. In particular, while joint probabilities associated with spacelike separated m…
Super-additivity of quantum capacity in simple channels
Zhen Wu, Qi Zhao, Zhihao Ma
The super-additivity of quantum channel capacity is an important feature of quantum information theory different from classical theory, which has been attracting attention. Recentl…
