High-Rate Continuous-Variable Quantum Key Distribution with Orbital Angular Momentum Multiplexing
Entropy, 2021 The secret key rate is one of the main obstacles to the practical application of continuous-variable quantum key distribution (CVQKD). In this paper, we propose a multiplexing scheme to increase the secret key rate of the CVQKD system with orbital ...

Ancilla-free continuous-variable SWAP test [PDF]
Quantum, 2022 We propose a continuous-variable (CV) SWAP test that requires no ancilla register, thereby generalizing the ancilla-free SWAP test for qubits. In this ancilla-free CV SWAP test, the computational basis measurement is replaced by photon number-resolving ...
