Number-phase uncertainty relations and bipartite entanglement detection in spin ensembles
Giuseppe Vitagliano, Matteo Fadel, Iagoba Apellaniz +4
We present a method to detect bipartite entanglement based on number-phase-like uncertainty relations in split spin ensembles. First, we derive an uncertainty relation that plays t…
Entanglement between two spatially separated atomic modes
Karsten Lange, Jan Peise, Bernd Lücke +6
Modern quantum technologies in the fields of quantum computing, quantum simulation and quantum metrology require the creation and control of large ensembles of entangled particles.…
0.75 atoms improve the clock signal of 10,000 atoms
I. Kruse, K. Lange, J. Peise +8
Since the pioneering work of Ramsey, atom interferometers are employed for precision metrology, in particular to measure time and to realize the second. In a classical interferomet…
Entanglement and extreme spin squeezing of unpolarized states
Giuseppe Vitagliano, Iagoba Apellaniz, Matthias Kleinmann +3
We present criteria to detect the depth of entanglement in macroscopic ensembles of spin-j particles using the variance and second moments of the collective spin components. The cl…
