Communication security has to evolve to a higher plane in the face of the threat from the
massive computing power of the emerging quantum computers. Quantum secure direct …

Quantum secure direct communication (QSDC) is a unique technique, which supports the
secure transmission of confidential information directly through a quantum channel without …

Quantum secure direct communication (QSDC) leverages quantum states to transmit
information securely and reliably over a noisy, lossy, and wiretapped quantum channel. It …

The recent launch of the Micius quantum-enabled satellite heralds a major step forward for
long-range quantum communication. Using single-photon discrete-variable quantum states …

The measurement of quantum signals that travel through long distances is fundamentally
and technologically interesting. We present quantum-limited coherent measurements of …

Current satellite-based quantum key distribution (QKD) is limited to nighttime operations,
and the reliance on microwave communication for key distillation leads to significant delays …

Global quantum communications will enable long-distance secure data transfer, networked
distributed quantum information processing, and other entanglement-enabled technologies …

The establishment of a world-wide quantum communication network relies on the synergistic
integration of satellite-based links and fiber-based networks. The first are helpful for long …

The establishment of quantum communication links over a global scale is enabled by
satellite nodes. We examine the influence of the Earth's atmosphere on the performance of …
