The first Quantum Key Distribution (QKD) protocol has been proposed by Bennett and Brassard in 1984. Since then, the security of QKD has always been the central issue in the quantum cryptographic field. Trace distance
Initialization of composite quantum systems into highly entangled states is usually a must to enable their use for quantum technologies. However, unavoidable noise in the preparation stage makes the system state mixed, hindering this goal.
A team of Italian and Chinese researchers propose a method that uses entangled photons as radar probes. The quantum radar methods so far proposed could determine the distance to an object more precisely than classical
Researchers at Delft University of Technology have developed a spintronic sensor that is only 11 atoms in size. The sensor is capable of capturing spin magnetic waves and consists of an antenna, a readout capability,
Distributing entangled photon pairs over noisy channels is an important task for various quantum information protocols. Encoding an entangled state in a decoherence-free subspace (DFS) formed by multiple photons is a promising way to circumvent
This is a very interesting paper published by well-known people of the Quantum Community. Quantum computational supremacy arguments, which describe a way for a quantum computer to perform a task that cannot also be done
A scientist, Dr Benjamin Brown, at the University of Sydney has developed a type of error-correcting code for quantum computers that will free up more hardware to do useful calculations and allow to design better
Physicists at the National Institute of Standards and Technology (NIST) have managed a molecule-atom entanglement. They entangled an electrically charged atom and an electrically charged molecule, paving the road towards a hybrid quantum information system.
Researchers at the University of Bristol has developed the first integrated photon source with the potential to deliver large-scale quantum photonics. Integrated quantum photonics is a promising platform for developing quantum technologies due to its
QuTech has demonstrated a new setup for fast turnaround testing and validation of quantum materials and devices. The setup uses ordinary electronic chip components that can operate at extreme cryogenic temperatures, and can be readily
