For the first time, researchers in China have demonstrated how quantum dots can be engineered to consistently generate pairs of entangled photons. By carefully tailoring the photonic environment ...

The collaboration of TU Wien with research groups in China has resulted in a crucial building block for a new kind of quantum computer: The realization of a novel type of quantum logic gate makes it ...

A team of physicists has uncovered a hidden topological structure within one of the most widely used sources of quantum entanglement.

The experimental layout of the sender Alice and the receiver Bob. Alice’s setup contains the excitation and collection setup of the single photon source, and a Sagnac-like polarization modulator for ...

A pair of photons enters an optical maze, and sometimes they leave as something new. Not new in the everyday sense, since both were still photons when they came out. But new in the way they share ...

A quantum internet is only as useful as its reach, and in a first, researchers created more than a million qubit pairs across ...
