Prototype Could be Used to Connect Quantum Computers

Physicists from the Institute of Science and Technology Austria (IST Austria) used a mechanical oscillator to produce entangled radiation. According to the research team, this is the first time a mechanical object has been used to create entangled radiation. Beyond its significance for fundamental physics, such a device could someday be used to link sensitive quantum computers with the optical fibers that connect computer networks. Classical computers are typically connected through optical fibers, because optical radiation is robust against disturbances that could corrupt or destroy data. In order to apply this technology to quantum computers, a link that can convert the quantum computer’s microwave photons to optical...
