World's First Programmable Quantum Photonic Chip

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."

Entangling photons is a bad idea.

It takes hours to sort them out afterwards.

Re:Bristol group: uncertainty

[petes_PoV]

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.
