Discussion Overview

The discussion centers on whether a CNOT (Controlled-NOT) gate has been physically constructed. Participants explore the existence and implementation of CNOT gates in quantum computing, referencing various sources and examples.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the existence of a physically built CNOT gate.
  • Another participant asserts that there are several physical realizations of CNOT gates and provides a link to support this claim.
  • A third participant confirms that CNOT gates have been constructed and mentions specific quantum circuits that utilize them, including links to proposed circuits.
  • One participant claims that the invention of CNOT gates can be attributed to Japanese researchers.

Areas of Agreement / Disagreement

Participants present multiple viewpoints regarding the existence and development of CNOT gates, indicating that there is no consensus on the specifics of their invention or realization.

Could somebody tell me whether or not a CNOT gate has actually been built or not?

Thanks,

I believe there are several CNOT physical realisation up to today. One of them:
