World's First Programmable Quantum Photonic Chip

Posted by samzenpus on from the future-chip dept.

MrSeb writes "A team of engineering geniuses from the University of Bristol, England has developed the world's first re-programmable, multi-purpose quantum photonic computer chip that relies on quantum entanglement to perform calculations. With multiple waveguide channels (made from standard silicon dioxide), and eight electrodes, the silicon chip is capable of repeatedly entangling photons. Depending on how the electrodes are programmed, different quantum states can be produced. The end result is two qubits that can be used to perform quantum computing. Most importantly, though, unlike existing quantum photonic setups which require apparatus the size of a 'large dining table,' this new chip is tiny: just 70mm (2.7 inches) by 3mm."

    but can you link it to the inverted phase-induced sub-space harmonic protocol analyzer to initiate a modulated tachyon pulse?

      Yes, but only if you reverse the polarity first.

      Yes, but only if you reverse the polarity first.

      Don't forget to reroute it all through the main deflector dish.

    i know! one time i slept on about 60 cat-5 cables on a 200+ person man LAN, it wasn't too bad. maybe if i laid in bed, and then had the chips on top of me? thanks for the input though :) i slept next to my frigid bitch of a ex girlfriend, so if i can handle near absolute zero temperatures, this should be a walk in the park.

      The trick is to keep Schroedinger's cat away from your photon strings.

    Unfortunately, after you program it you no longer know where it is.

    how many quantum computer groups are there likely to be in Bristol?

    You can either know where they are, or how many there are - but not both.
