Focus on Quantum Memories
Gavin Brennen, Elisabeth Giacobino, Christoph Simon
Quantum memories are essential for quantum information processing and long-distance quantum communication. The field has recently seen a lot of progress, and the present focus issu…
Weak values in a classical theory with an epistemic restriction
Angela Karanjai, Eric G. Cavalcanti, Stephen D. Bartlett +1
Weak measurement of a quantum system followed by postselection based on a subsequent strong measurement gives rise to a quantity called the weak value: a complex number for which t…
Heuristic for estimation of multiqubit genuine multipartite entanglement
Paulo E. M. F. Mendonca, Marcelo A. Marchiolli, Gerard J. Milburn
For every N-qubit density matrix written in the computational basis, an associated "X-density matrix" can be obtained by vanishing all entries out of the main- and anti-diagonals.…
Experimental Simulation of Closed Timelike Curves
Martin Ringbauer, Matthew A. Broome, Casey R. Myers +2
Closed timelike curves are among the most controversial features of modern physics. As legitimate solutions to Einstein's field equations, they allow for time travel, which instinc…
Heisenberg-limited metrology with a squeezed vacuum state, three-mode mixing, and information recycling
Behnam Tonekaboni, Simon A. Haine, Stuart S. Szigeti
We have previously shown that quantum-enhanced atom interferometry can be achieved by mapping the quantum state of squeezed optical vacuum to one of the atomic inputs via a beamspl…
Linear Optical Quantum Metrology with Single Photons: Exploiting Spontaneously Generated Entanglement to Beat the Shot-Noise Limit
Keith R. Motes, Jonathan P. Olson, Evan J. Rabeaux +3
Quantum number-path entanglement is a resource for super-sensitive quantum metrology and in particular provides for sub-shotnoise or even Heisenberg-limited sensitivity. However, s…
