Chinese physicists realized a genuine entanglement of 18 quantum particles, beating their own world record set in 2016, while the team has set their next goal at 50-qubit entanglement.
The result of the study was published in the US journal Physical Review Letters on June 28.
Chinese leading quantum physicist PAN Jianwei led the project. Together with his team, PAN earlier demonstrated quantum entanglement with 10 quantum bits, or "qubits," in 2016, according to a report sent by PAN's team to Global Times on Tuesday.
Professor Pan Jianwei with University of Science and Technology of China (USTC) was presented Willis E.Lamb Award at 48th Physics of Quantum Electronics conference held in Salt Lake City of State of Utah, USA, on Jan. 10.
BEIJING - As the first to achieve quantum key distribution from a satellite to the ground, China is confident in making more scientific and technological breakthroughs.
The achievement, based on experiments conducted with the world's first quantum satellite -- Quantum Experiments at Space Scale (QUESS), lays a foundation for building a hack-proof global quantum communication network.
QUESS, nicknamed "Micius" after a fifth century B.C. Chinese philosopher and scientist, was launched on Aug. 16, 2016.
China has become the first country to send quantum keys－highly complex encryptions－from a satellite to a base on Earth, and to teleport light particles the other way.
The accomplishments are two major breakthroughs in the effort to create an unhackable global communications network.
The two experiments mark the completion of the the second and third of the three main goals of Micius, the world's first quantum communications satellite, which China launched last year.
Quantum entanglement—physics at its strangest—has moved out of this world and into space. In a study that shows China's growing mastery of both the quantum world and space science, a team of physicists reports that it sent eerily intertwined quantum particles from a satellite to ground stations separated by 1200 kilometers, smashing the previous world record. The result is a stepping stone to ultrasecure communication networks and, eventually, a space-based quantum internet.
LU Chaoyang was awarded the 2017 Fresnel prize for fundamental aspects for his outstanding achievement in quantum light sources, quantum teleportation and optical quantum computing, announced by the European Physical Society. The Plenary Ceremony will take place on June 27th in Munich, Germany.
The prize is named after Augustin-Jean Fresnel, a leading physicist in the 19th century. It is regarded as the highest global honor for scientists under the age of 35 in the field of quantum electronics and optics.
