Efficient generation and reliable distribution of quantum entangled states is crucial for emerging quantum applications, including quantum key distribution (QKDs). However, conventional ...

Quantum communication could enable uncrackable transfer of information, but most approaches rely on trusted devices. Researchers have now demonstrated that a new method that does away with this ...

Quantum entanglement occurs when two subatomic particles become linked in such a way that their properties remain connected, no matter how far apart they are. A change to one particle seems to ...

IonQ deployed what it claims to be the largest and most complex quantum key distribution (QKD) network in Europe. The initiative came out of a project with Romanian institutions, including the ...

MicroCloud Hologram Inc. has announced a groundbreaking proposal for a high-dimensional quantum key distribution (QKD) protocol that utilizes quantum Fourier transform and quantum-controlled NOT gate ...
