Ability of stabilizer quantum error correction to protect itself from its own imperfection
The theory of stabilizer quantum error correction allows us to actively stabilize quantum states and simulate ideal quantum operations in a noisy environment. It is critical is to correctly diagnose noise from its syndrome and nullify it accordingly. However, hardware that performs quantum error correction itself is inevitably imperfect in practice. Here, we show that stabilizer codes possess a...
متن کاملStabilizer formalism for operator quantum error correction.
Operator quantum error correction is a recently developed theory that provides a generalized and unified framework for active error correction and passive error avoiding schemes. In this Letter, we describe these codes using the stabilizer formalism. This is achieved by adding a gauge group to stabilizer codes that defines an equivalence class between encoded states. Gauge transformations leave...
متن کاملQuantum Error-Correction Codes on Abelian Groups
We prove a general form of bit flip formula for the quantum Fourier transform on finite abelian groups and use it to encode some general CSS codes on these groups.
متن کاملApproaches to Quantum Error Correction
We have persuasive evidence that a quantum computer would have extraordinary power. But will we ever be able to build and operate them? A quantum computer will inevitably interact with its environment, resulting in decoherence and the decay of the quantum information stored in the device. It is the great technological (and theoretical) challenge to combat decoherence. And even if we can suitabl...
متن کاملIntroduction to Quantum Error Correction
with |α| + |β| = 1. The physical state of n particles is described by a vector in the Hilbert space H⊗n, which consists of all complex linear combinations of products |x1〉⊗|x2〉⊗· · ·⊗|xn〉, where |xi〉 ranges over the two basis vectors of the i-th copy of the Hilbert space H. Typically one uses the convention xi ∈ {0, 1} and the basis vectors of the 2-dimensional complex vector spaceH⊗n are writt...
