Quantum Complementarity Approach to Device-Independent Security
Xingjian Zhang, Pei Zeng, Tian Ye +2
Complementarity is an essential feature of quantum mechanics. The preparation of an eigenstate of one observable implies complete randomness in its complementary observable. In qua…
Reference-frame-independent design of phase-matching quantum key distribution
Anran Jin, Pei Zeng, Richard V. Penty +1
The recently proposed phase-matching quantum key distribution offers means to overcome the linear key rate-transmittance bound. Since the key information is encoded onto the phases…
Universal quantum algorithmic cooling on a quantum computer
Pei Zeng, Jinzhao Sun, Xiao Yuan
Quantum cooling, a deterministic process that drives any state to the lowest eigenstate, has been widely used from studying ground state properties of chemistry and condensed matte…
Characterizing correlation within multipartite quantum systems via local randomized measurements
Zhenhuan Liu, Pei Zeng, You Zhou +1
Given a quantum system on many qubits split into a few different parties, how many total correlations are there between these parties? Such a quantity, aimed to measure the deviati…
