Sentences with phrase «coherence times»

We combine these techniques to detect nuclear magnetic resonance from dilute 31P in the purest available sample of 28Si, at concentrations inaccessible to conventional measurements, measuring a solid - state coherence time of over 180 seconds.

Nitrogen Vacancy (NV) color centers exhibit remarkable and unique properties, including long coherence times at room temperature (~ ms), optical initialization and readout, and coherent microwave control.

This is because holes have reduced hyperfine coupling to nuclear spins, allowing long spin coherence times [1], while the enhanced spin - orbit coupling of holes enables fast all - electric spin manipulation via EDSR [2].

With improvements of coherence times by over 5 order of magnitude, it is now possible to implement simple quantum algorithms with these circuits.

In the language of physics, they have a short coherence time.

«Also, we could reach the ideal condition of running the clock with its full coherence time, which refers to how long a series of ticks can remain stable.

These qubits, taken individually, have demonstrated world - record coherence times.

The 29Si isotope is present at 4.67 percent in natural silicon and is the only stable isotope of silicon that carries a nuclear spin limiting the qubit coherence time.

showing that long coherence times can be achieved.

Since 2012, when the first qubits that relied on electron spins were reported, the introduction of isotopically purified 28Si has led to significant enhancement of the spin coherence time.

Steger et al. (p. 1280) demonstrate that the nuclear spins of 31P impurities in an almost isotopically pure sample of 28Si can have a coherence time of as long as 192 seconds at a temperature of ∼ 1.7 K.

In diamond at room temperature, Maurer et al. (p. 1283) show that a spin - based qubit system comprised of an isotopic impurity (13C) in the vicinity of a color defect (a nitrogen - vacancy center) could be manipulated to have a coherence time exceeding one second.

Coherence times must improve, quantum error rates must decrease, and eventually, we must mitigate or correct the errors that do occur.

Compared with Ye's previous 1 - D clocks, the new 3 - D quantum gas clock can reach the same level of precision more than 20 times faster due to the large number of atoms and longer coherence times.

The ability to scale up both the atom number and coherence time will make this new - generation clock qualitatively different from the previous generation.»

Coherence times are also limited by collisions.

By extending the coherence time of electron states to over half a second, a team of scientists from Berkeley Lab, UC Berkeley, and Harvard University has vastly improved the performance of one of the most potent possible sensors of magnetic fields on the nanoscale — a diamond defect no bigger than a pair of atoms, called a nitrogen vacancy (NV) center.

Electron spins in silicon quantum dots are attractive systems for quantum computing owing to their long coherence times and the promise of rapid scaling of the number of dots in a system using semiconductor fabrication techniques.
