Thermal‐Driven Diode Polarity Switching From Competing Helical Superconducting States in WTe2/α‐Fe2O3 Heterostructures

Advanced Materials, EarlyView.
A Nb‐proximitized Josephson junction based on a WTe2/α‐Fe2O3 heterostructure exhibits a robust superconducting diode effect with programmable polarity. The diode direction can be trained by magnetic fields and switched by temperature cycling, revealing tunable finite‐momentum pairing states and competing superconducting states in symmetry‐broken ...

Quantum key distribution with a control key

2017 International Symposium on Wireless Communication Systems (ISWCS), 2017
Quantum key distribution (QKD) relies on randomness to exchange secret keys among the communicating parties. While ensuring the secrecy of the keys being distributed, independent randomness also causes to reduce the number of key bits that can be shared per quantum signal exchanged.

Key for a Hidden Quantum State

Physical Review Letters, 2022
Quantum trajectories are crucial to understanding the evolution of open systems. We consider an open cavity mode undergoing up and down multistate quantum jumps due to the emission and absorption of photons. We prove that among all subtrajectories, starting simultaneously from different photon number states, only one survives a long single-run ...

A Tutorial on Quantum Key Distribution

2015 10th International Conference on Broadband and Wireless Computing, Communication and Applications (BWCCA), 2015
Quantum Key Distribution (QKD) technology, based on quantum uncertainty principle, no-cloning theorem and Heisenberg uncertainty principle, can generate information-theoretically secure keys for communication parties. Typical QKD systems include the quantum communication phase and the post-processing phase and can be divided into three families: Device
