Running an experiment in the IBM Quantum Experience - Duration:. We implement multiple quantum error correction cycles for phase- flip. One of the most straightforward error- correcting codes is the repetition code. quantum repetition code that. any errors, an experiment or realistic. Title: Experimental Quantum Error Correction. The experiment implemented the 3- bit code for phase errors in liquid state state NMR. The quantum eraser experiment described in this article is a variation of Thomas Young' s classic double- slit experiment. It establishes that when action is taken to determine which slit a photon has passed through, the photon cannot interfere with itself. used higher quantum states of a superconducting- based quantum circuit to demonstrate a method for the fault- tolerant measurement of an error- correctable logical qubit.

Such fault- tolerant measurements will allow more frequent interrogations of the state of the logical qubit, ultimately leading to the implementation of more quantum operations and more complex entangled quantum circuits. The journey to realizing functional quantum computers will be long and it' s a path that Q- CTRL is committed to making as easy as possible for you. Researchers demonstrate a superconducting quantum system that would allow for error correction. Faithful transmission of quantum information is a crucial ingredient in quantum communication networks. To overcome the unavoidable decoherence in a noisy channel, to date, many efforts have been made to transmit one.
