Sentence examples for below the quantum error from inspiring English sources

While the optimization yields a gate error well below the quantum error correction threshold, it deviates significantly from the simple geometric phase gate scheme, resulting in complex dynamics.

While such a small deviation is not discernible in the plot of the population in panel (d), it is nonetheless a significant error in the objective of obtaining high fidelity gates below the quantum error correction limit, typically resulting in gate errors below 10−3.

Quantum states to prevent eavesdropping Throughout the moves, Gottesman continued to work on quantum error correction, but he also moved into the field of quantum cryptography, which uses quantum states to prevent eavesdropping.

The enormous recent progress in this field comprises, for example, the realization of quantum teleportation  [3] and complex two- and three-qubit algorithms, including number factoring and quantum error correction  [4 8].

"In order for a quantum error-correcting code to work, it must prevent the environment from learning about the encoded quantum state?because measuring a quantum state will necessarily disturb it.

This built-in secrecy makes quantum error-correcting codes ideal for quantum cryptography," says Gottesman.

It can be seen that below the quantum-classical crossover temperature (which is the temperature below which classical and quantum mechanics diverge; in this system 260 K for H2, 190 K for D2) the effective quantum energy barrier decreases as the temperature is lowered.

For the values of the quantum yield an error of 10% in regard to the measurement procedure was assumed.

About 10% errors on the quantum yields are estimated due to the systematic errors (extrapolation, instrument wavelength-dependent sensitivity, polarization effects, etc).

The luminescence has a lifetime of several microseconds and the quantum yield below 0.1%.

If someone listens in on a message encrypted with a quantum key, it causes a collapse of the quantum state and leads to an error that can be detected on the receiving end.
