Direct tomography of high-dimensional density matrices for general quantum states of photons
Yiyu Zhou, Jiapeng Zhao, Darrick Hay +3
Quantum state tomography is the conventional method used to characterize density matrices for general quantum states. However, the data acquisition time generally scales linearly w…
Performance analysis of d-dimensional quantum cryptography under state-dependent diffraction
Jiapeng Zhao, Mohammad Mirhosseini, Boris Braverman +7
Standard protocols for quantum key distribution (QKD) require that the sender be able to transmit in two or more mutually unbiased bases. Here, we analyze the extent to which the p…
Optimal measurements for quantum multiparameter estimation with general states
Jing Yang, Shengshi Pang, Yiyu Zhou +1
We generalize the approach by Braunstein and Caves [Phys. Rev. Lett. 72, 3439 (1994)] to quantum multi-parameter estimation with general states. We derive a matrix bound of the cla…
