Measurement-based estimator scheme for continuous quantum error correction

نویسندگان

چکیده

Canonical discrete quantum error correction (DQEC) schemes use projective von Neumann measurements on stabilizers to discretize the syndromes into a finite set, and fast unitary gates are applied recover corrupted information. Quantum (QEC) based continuous measurement, known as (CQEC), in principle, can be executed faster than DQEC also resource efficient. However, CQEC requires meticulous filtering of noisy measurement data reliably extract basis which errors could detected. In this paper, we show that by constructing measurement-based estimator (MBE) logical qubit protected, is driven currents stabilizers, it possible accurately track occurring physical qubits real time. We MBE develop (MBE-CQEC) scheme protect high degree, surpassing performance DQEC, allows QEC conducted either immediately or delayed time with instantaneous feedbacks.

Measurement-based quantum error correction

Measurement-based (or one-way) quantum error correction (MBQEC) is a method with the capability to detect and correct any errors present in a measurement-based quantum computation (MBQC) setup [1]. There are a variety of methods and protocols we can use to perform QEC, although few that have been successfully implemented experimentally [2, 3]. An MBQC protocol requires a resource state and will...

Continuous quantum error correction

We describe new implementations of quantum error correction that are continuous in time, and thus described by continuous dynamical maps. We evaluate the performance of such schemes using numerical simulations, and comment on the effectiveness and applicability of continuous error correction for quantum computing.

Error Correction for Continuous Quantum Variables

Quantum computers hold the promise for efficiently factoring large integers [1]. However, to do this beyond a most modest scale they will require quantum error correction [2]. The theory of quantum error correction is already well studied in two-level or spin2 systems (in terms of qubits or quantum bits) [2–7]. Some of these results have been generalized to higher-spin systems [8–11]. This work...
