Resolution-enhanced entanglement detection
Manuel Gessner, Luca Pezzè, Augusto Smerzi
We formulate a general family of entanglement criteria for multipartite systems. Fisher information criteria compare the sensitivity to unitary rotations with the variances of suit…
Quantum metrology with nonclassical states of atomic ensembles
Luca Pezzè, Augusto Smerzi, Markus K. Oberthaler +2
Quantum technologies exploit entanglement to revolutionize computing, measurements, and communications. This has stimulated the research in different areas of physics to engineer a…
Efficient entanglement criteria for discrete, continuous, and hybrid variables
Manuel Gessner, Luca Pezzè, Augusto Smerzi
We provide a method to construct entanglement criteria for arbitrary multipartite systems of discrete or continuous variables and hybrid combinations of both. While any set of loca…
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…
