Anomalous weak values in a generalized Mach-Zehnder interferometer extracted directly from intensity measurements
Ismaele V. Masiello, Hartmut Lemmel, Andreas Dvorak +2
Weak values provide a powerful framework for characterizing quantum systems. Their experimental extraction conventionally relies on weak conditioned von Neumann measurements, invol…
Tight qubit uncertainty relations studied through weak values in neutron interferometry
Andreas Dvorak, Ismaele V. Masiello, Yuji Hasegawa +3
In its original formulation, Heisenberg's uncertainty principle describes a trade-off relation between the error of a quantum measurement and the thereby induced disturbance on the…
Orbital Angular Momentum Generation in Schwinger Scattering from Perfect Quartz
Niels Geerits, Anna-Sophie Berger, Hartmut Lemmel +4
Static electric fields have been suggested as a spin to orbital angular momentum converter in neutrons. Initial calculations showed that the field required to facilitate significan…
Covariant correlation-disturbance and its experimental realization with spin-1/2 particles
Ali Asadian, Florian Gams, Stephan Sponar
We formulate a precise tradeoff relation between correlation and disturbance for sequential -outcome quantum measurements in Hilbert spaces of arbitrary dimension. This relation…
Measuring the Angular Momentum of a Neutron Using Earth's Rotation
Niels Geerits, Stephan Sponar, Kyle E. Steffen +6
A coupling between Earths rotation and orbital angular momentum (OAM), known as the Sagnac effect, is observed in entangled neutrons produced using a spin echo interferometer. Afte…
