3/19/2023 0 Comments Quantum error channels onlineThe operations that you perform on the qubits are faulty themselves as well, and in a proper simulation of a QECC this has to be taken into account. Quantum error correction is used to protect information in quantum communication (where quantum states pass through noisy channels) and quantum computation (where quantum states are transformed through a sequence of imperfect computational steps in the presence of environmental decoherence to solve a computational problem). Further details can be found in the supporting online material on Science Online. The error rates are mostly expressed in the damping time $T_$ say only something about what happens to your qubits when they are idle. Communication over a noisy quantum channel introduces errors in the. Now, if you want to simulate actual systems more closely, as I explained in my answer linked above, it's 'better' to use the amplitude damping and dephasing channel. This excellent answer elaborates a bit on why we call it the pseudo threshold, and not just threshold. it creates more errors than it can correct) for a low $p$ the code will actually do some good, and thus an interesting value for $p$ might be the point where the code starts to add benefit - this value is often referred to as the pseudo threshold. As you may be aware, for higher $p$, a code may do more bad than good (i.e. Posted Feb 09, 2022, 18:00 The above link for live-cast has been updated. Posted Feb 10, 2022, 13:20 Recording for Feb 10 lecture uploaded. Posted Feb 11, 2022, 21:30 Assignment 4 updated (revision also available on Slack). We analyze a generalized quantum error-correction code against photon. We will just keep updating the above link. Cat Man is online now Related Heavy Equipment Questions Cat c9 power pack machine. Moreover, what is much more interesting is to perform the simulation for a range of values of $p$, and see how the performance of the code depends on $p$. Each live-cast seems to have a unique link. So for simulations where you, for instance, investigate the performance of some code against the depolarizing channel, it doesn't really matter what the exact value of $p$ is in your simulations. As I explained in my answer on a previous question of yours, the depolarizing channel is not really 'physical' - actual quantum systems don't really behave that way.
