Advantage of Hardy's Nonlocal Correlation in Reverse Zero-Error Channel Coding

Mir Alimuddin, Ananya Chakraborty, Govind Lal Sidhardh +5

Hardy's argument constitutes an elegant proof of quantum nonlocality. In this work, we report an exotic application of Hardy's nonlocal correlations in two-party communication setu…

The battery capacity of energy-storing quantum systems

Xue Yang, Yan-Han Yang, Mir Alimuddin +5

The quantum battery capacity is introduced in this letter as a figure of merit that expresses the potential of a quantum system to store and supply energy. It is defined as the dif…
