Neutron State Entanglement with Overlapping Paths
S. J. Kuhn, S. McKay, J. Shen +12
The development of direct probes of entanglement is integral to the rapidly expanding field of complex quantum materials. Here we test the robustness of entangled neutrons as a qua…
An Operator Analysis of Contextuality Witness Measurements for Multimode-Entangled Single Neutron Interferometry
Shufan Lu, Abu Ashik Md. Irfan, Jiazhou Shen +5
We develop an operator-based description of two types of multimode-entangled single-neutron quantum optical devices: Wollaston prisms and radio-frequency spin flippers in inclined…
Unveiling contextual realities by microscopically entangling a neutron
J. Shen, S. J. Kuhn, R. M. Dalgliesh +13
The development of qualitatively new measurement capabilities is often a prerequisite for critical scientific and technological advances. The dramatic progress made by modern probe…
Certified Quantum Measurement of Majorana Fermions
Abu Ashik Md. Irfan, Karl Mayer, Gerardo Ortiz +1
We present a quantum self-testing protocol to certify measurements of fermion parity involving Majorana fermion modes. We show that observing a set of ideal measurement statistics…
