http://www.cs.tulane.edu/quantum/slides/PR18/MURIFinal.pptx The Eastin–Knill theorem is a no-go theorem that states: "No quantum error correcting code can have a continuous symmetry which acts transversely on physical qubits". In other words, no quantum error correcting code can transversely implement a universal gate set. Since quantum computers are … See more The approximate version of the Eastin–Knill theorem states: "If a code admits a continuous symmetry pertaining to a Lie group and corrects erasure with fixed accuracy, then for each logical qubit, a number of physical … See more The Eastin–Knill theorem does not prohibit protocols that provide fault tolerant quantum computation. Some methods of getting around … See more WebOct 18, 2024 · However, the Eastin-Knill theorem says that not all unitaries in a universal set can be implemented transversally. So there will be (at least) one gate in the set with a much higher depth, and that may be your critical case. In many implementations, the non-transversal gate is chosen to be the T gate. ... noridian webinar part a
