First, the processing medium is different: integrated circuit chips are the transmission, distribution, decoding and calculation of electronic signals, and quantum chips are the processing of optical quantum signals, which determines the essence of quantum chips and electronic chips are different.
Second, the processing speed is different: optical quantum transmission is faster, the connection between the chips is optical fiber, and the lines in the chip should also be assisted by superconducting technology, so the current electronic chip in addition to the auxiliary circuit around the quantum computer, the core part of the optical quantum computer is optical quantum signal processing, and the electronic chip is basically not suitable for the computing part of the core of the quantum computer.
To the quantum chip level and today's integrated chips will not be much different, because the quantum system into the electronic circuit level, today's mature integrated circuit chip technology can be fully used.
