Completely zero-field operation is desirable for scaling up a quantum computer based on superconducting qubits. Here we demonstrate quantum error correction to protect the nuclear spin of the nitrogen as a quantum memory in a diamond nitrogen-vacancy center with two nuclear spins of the surrounding ...
Quantum error correction for quantum memoriesQuantum error correction for quantum memoriesdoi:10.1103/RevModPhys.87.307Active quantum error correction using qubit stabilizer codes has emerged as a promising, but experimentally challenging, engineering program for building a universal quantum computer. In this...
Fault-tolerant quantum memory plays a key role in interfacing quantum computers with quantum networks to construct quantum computer networks. Manipulation of spin quantum memory generally requires a magnetic field, which hinders the integration with supe

An Introduction to Quantum Error Correction Quantum states are very delicate, so it is likely some sort of quantum error correction will be necessary to build reliable quantum computers. The theory o... D Gottesman 被引量: 142发表: 2000年 Quantum error correction for quantum memories Active quan...
Incorporating protection against quantum errors into adiabatic quantum computing (AQC) is an important task due to the inevitable presence of decoherence. Here, we investigate an error-protected encoding of the AQC Hamiltonian, where qubit ensembles are

From our single-photon-error, cold-cavity loading analysis for the trapped Rb atom quantum memories =-=[5,6]-=-, see Fig. 3, we have derived [7] the conditional joint density operator, given no erasure, that accounts for pump phase, gain, and detuning errors in a dual-OPA ...
The development of quantum memories for quantum repeaters is a long-term solution to this short range but is far from maturity [86]. For example, Gravity Probe B cost USD750M and took over 50 years of development [87], whilst the Hubble Space Telescope cost USD4.7B to launch [88] and...
Quantum-enhanced measurements hold the promise to improve high-precision sensing ranging from the definition of time standards to the determination of fundamental constants of nature. However, quantum sensors lose their sensitivity in the presence of noi
