Efficient Quantum Error Correction for Fully Correlated Noise
نویسندگان
چکیده
We investigate an efficient quantum error correction of a fully correlated noise. Suppose the noise is characterized by a quantum channel whose error operators take fully correlated forms given by σ x , σ ⊗n y and σ ⊗n z , where n > 2 is the number of qubits encoding the codeword.

The upside of noise: engineered dissipation as a resource in superconducting circuits
Historically, noise in superconducting circuits has been considered an obstacle to be removed. A large fraction of the research effort in designing superconducting circuits has focused on noise reduction, with great success, as coherence times have increased by four orders ofmagnitude in the past two decades. However, noise and dissipation can never be fully eliminated, and further, a rapidly g...
متن کاملDecoherence by correlated noise and quantum error correction.
We study the decoherence of a quantum computer in an environment which is inherently correlated in time and space. We first derive the nonunitary time evolution of the computer and environment in the presence of a stabilizer error correction code, providing a general way to quantify decoherence for a quantum computer. The general theory is then applied to the spin-boson model. Our results demon...
متن کاملEffects of noise on quantum error correction algorithms
It has recently been shown that there are efficient algorithms for quantum computers to solve certain problems, such as prime factorization, which are intractable to date on classical computers. The chances for practical implementation, however, are limited by decoherence, in which the effect of an external environment causes random errors in the quantum calculation. To combat this problem, qua...
متن کاملQuantum Computers: Noise Propagation and Adversarial Noise Models
In this paper we consider adversarial noise models that will fail quantum error correction and fault-tolerant quantum computation. We describe known results regarding high-rate noise, sequential computation, and reversible noisy computation. We continue by discussing highly correlated noise and the “boundary,” in terms of correlation of errors, of the “threshold theorem.” Next, we draw a pictur...
