A team at the University of Science and Technology of China (USTC) has demonstrated the teleportation of high-dimensional states in a three-dimensional six-photon system. Compared with two-dimensional systems, high-dimensional system quantum networks have the advantages
A joint group of scientists has demonstrated that temperature difference can be used to entangle pairs of electrons in superconducting structures. The researchers designed a device where a superconductor was layered withed graphene and metal
Researchers at Universita degli Studi Roma Tre and University of Florence have characterized the energetic footprint of a two-qubit quantum gate from the perspective of non-equilibrium quantum thermodynamics. Despite the significant progress made towards the
Ilyas Khan, CEO of UK quantum startup Cambridge Quantum Computing, is the third nominee of the ‘Quantum Personality of the Year 2020’. He founded the company in 2014, when the wording ‘quantum’ was anything but trendy.
Quantum Key Distribution (QKD) protocols are performed by sending a sizeable, but finite, number of quantum signals between the distant parties involved. Many QKD experiments, however, predict their achievable key rates using asymptotic formulas, which
The Dutch startup Qblox wins CES 2021 Innovation Award honoree for its qubit control hardware – the Cluster series and announces it secures $6Mn in seed funding from the European Innovation Council – Horizon 2020.
Quantum annealers are devices that physically implement a quantum system called the Ising model to solve combinatorial optimization problems like the famous traveling salesman problem. In the late 90s, scientists found that combinatorial optimization problems
Light-based processors, called photonic processors, enable computers to complete complex calculations at incredible speeds. A team of researchers has examined the potential of photonic processors for artificial intelligence applications. The results demonstrated for the first
Scientists have found a way to grow diamonds in the lab that can be stressed and strained to give them special electricity-conducting properties. In addition to being tough, diamonds are highly conductive when it comes to
Chinese scientists have established the world’s first integrated quantum communication network, combining over 700 optical fibers on the ground with two ground-to-satellite links to achieve Quantum Key Distribution (QKD) over a total distance of 4,600
