A quantum internet is the holy grail of quantum information processing, enabling the
deployment of a broad range of quantum technologies and protocols on a global scale …

Over the past few decades, significant progress has been made in quantum information
technology, from theoretical studies to experimental demonstrations. Revolutionary quantum …

Concerted efforts are underway to establish an infrastructure for a global quantum Internet to
realise a spectrum of quantum technologies. This will enable more precise sensors, secure …

Optical photons are powerful carriers of quantum information, which can be delivered in free
space by satellites or in fibers on the ground over long distances. Entanglement of quantum …

Global-scale quantum communication links will form the backbone of the quantum internet.
However, exponential loss in optical fibres precludes any realistic application beyond few …

Digital payments have replaced physical banknotes in many aspects of our daily lives.
Similarly to banknotes, they should be easy to use, unique, tamper-resistant and …

Mechanical resonators, due to their capability to host ultralong-lived phonon modes, are
particularly attractive for quantum state storage and as memory elements in conjunction with …

Quantum networks provide a prospective paradigm to connect separated quantum nodes,
which relies on the distribution of long-distance entanglement and active feedforward control …

As the cornerstone of AI generated content, data drives human-machine interaction and is
essential for developing sophisticated deep learning agents. Nevertheless, the associated …

Entanglement between photons at telecommunication wavelengths and long-lived quantum
memories is one of the fundamental requirements of long-distance quantum communication …
