Quantum self-correction in the 3D cubic code model.
A big open question in the quantum information theory concerns the feasibility of a self-correcting quantum memory. A quantum state recorded in such memory can be stored reliably for a macroscopic time without need for active error correction, if the memory is in contact with a cold enough thermal bath. Here we report analytic and numerical evidence for self-correcting behavior in the quantum s...
متن کاملSupplementary Material: Numerical study of quantum self-correction in the 3D Cubic Code model
Here, we explain details of our numerical simulation. The interaction of the memory system with a thermal bath is simulated by Metropolis evolution. As we wish to observe low temperature behavior we adopt continuous time algorithm by Bortz, Kalos, and Lebowitz (BKL) [1]. A pseudo-random number generation package RngStream by L’Ecuyer [2] was used. As before, the coupling constant in the Hamilto...
متن کاملAnalytic and numerical demonstration of quantum self-correction in the 3D Cubic Code
A big open question in the quantum information theory concerns feasibility of a selfcorrecting quantum memory. A quantum state recorded in such memory can be stored reliably for a macroscopic time without need for active error correction if the memory is put in contact with a cold enough thermal bath. In this paper we derive a rigorous lower bound on the memory time Tmem of the 3D Cubic Code mo...
متن کاملFault-tolerant quantum error correction code conversion
In this paper we demonstrate how data encoded in a five-qubit quantum error correction code can be converted, fault-tolerantly, into a seven-qubit Steane code. This is achieved by progressing through a series of codes, each of which fault-tolerantly corrects at least one error. Throughout the conversion the encoded qubit remains protected. We found, through computational search, that the method...
متن کاملEntropy of a Quantum Error Correction Code
We define and investigate the notion of entropy for quantum error correcting codes. The entropy of a code for a given quantum channel has a number of equivalent realisations, such as through the coefficients associated with the Knill-Laflamme conditions and the entropy exchange computed with respect to any initial state supported on the code. In general the entropy of a code can be viewed as a ...
