چکیده انگلیسی:
To realize the Quantum Internet, quantum
communications require pre-shared entanglement among quantum nodes. However, both the generation and the distribution
of the maximally-entangled quantum states are inherently contaminated by quantum decoherence. Conventionally, the quantum
decoherence is mitigated by performing the consecutive steps of
quantum entanglement distillation followed by quantum teleportation. However, this conventional approach imposes a long delay.
To circumvent this impediment, we propose a novel quantum
communication scheme relying on realistic noisy pre-shared
entanglement, which eliminates the sequential steps imposing
delay in the standard approach. More precisely, our proposed
scheme can be viewed as a direct quantum communication
scheme capable of improving the quantum bit error ratio (QBER)
of the logical qubits despite relying on realistic noisy pre-shared
entanglement. Our performance analysis shows that the proposed
scheme offers competitive QBER, yield, and goodput compared
to the existing state-of-the-art quantum communication schemes,
despite requiring fewer quantum gates.
