5 days ago · Abstract. For quantum error correction codes the required number of measurement rounds typically increases with the code distance when measurements are faulty. Single-shot error correction allows for an error threshold with only one round of noisy syndrome measurements regardless of the code size.
4 days ago · toric code, the work you perform is called quantum error-correction [7]. In Section 3 we assign to each proof πin multiplicative linear logic a Hilbert space H π, quantum error-correcting code S π and Hamiltonian H π=−∑ X∈S π X. We think of JπK =(H π,S π) as either the quantum error-correcting code or the associated finite quantum ...
5 days ago · Research update. Quantum error correction produces better ‘magic’ states. 29 May 2024 Raman Choudhary. Error-corrected magic: Clifford circuits attain universality – that is, the ability to compute any function that quantum theory permits – upon injection of special states called magic states.
Quantum error correction (QEC) is vital to scalable quantum information processing applications. It uses entanglement ...
5 days ago · Given a fixed logical circuit of a certain depth and given a certain physical error probability (which must be below threshold) you can (in principle) choose an error correction code with a code distance that pushes logical error probabilities low enough for your circuit to do what it should do.
