When helium behaves like a black hole

A team of scientists has discovered that a law controlling the bizarre behavior of black holes out in space–is also true for cold helium atoms that can be studied in laboratories. Th...


The discovery of Majorana fermion

The research group in Shanghai Jiao Tong University (SJTU) achieved great breakthrough in the detection of Majorana fermion in the artificial topological superconductor, which is the...


How small can superconductors be?

Nature Communications For the first time, physicists have experimentally validated a 1959 conjecture that places limits on how small superconductors can be. If the superconducting g...


Chip-based quantum key distribution

Both devices, along with fibre coupled single photon detectors, represent the full photonic QKD system. Figure 2: Transmitter output for the BB84 states. While the key was generated ...


‘Blurred times’ in a quantum world

However, when quantum mechanical and gravitational effects are taken into account, this picture is no longer tenable, as the clocks mutually disturb each other and hands of the clock...


The future of search engines

Combining AI with the insights of annotators and the information encoded in domain-specific resources, he and his collaborators are developing new approaches to IR that will benefit ...
