Evidence of Uncollapsed Quantum Amplitudes After Consecutive Measurements
Christoph Adami, Lambert Giner, Jeff S. Lundeen +1
Two of the most common interpretations of quantum measurement disagree about the fate of quantum amplitudes after measurement, yet this disagreement has not previously led to exper…
Experimental demonstration of a multi-particle collective measurement for optimal quantum state estimation
Arman Mansouri, Kyle M. Jordan, Raphael A. Abrahao +1
We experimentally demonstrate a two-particle collective measurement proposed as the optimal solution to a quantum state estimation game. Our results suggest that, in practice, the…
All-optical turbulence mitigation for free-space quantum key distribution using stimulated parametric down-conversion
Aaron A. Aguilar-Cardoso, Cheng Li, Tobey J. B. Luck +4
In this work, we propose and demonstrate a turbulence-resilient scheme for free-space quantum communication. By leveraging the phase conjugation property of stimulated parametric d…
Can We Conjugate the Orbital Angular Momentum of a Single Photon with Nonlinear Optics? A Theoretical Analysis
Tobey Luck, Aarón Aguilar-Cardoso, Cheng Li +4
Stimulated parametric down-conversion (StimPDC) produces an idler beam that exhibits a phase conjugate of the spatial structure of the classical seed beam. Extending this effect to…
Fast and Automated Optical Polarization Compensation of Fiber Unitaries
Niklas Braband, Arman Mansouri, Riza Fazili +2
The polarization of light is critical in various applications, including quantum communication, where the photon polarization encoding a qubit can undergo uncontrolled changes when…
Enhancing interferometry using weak value amplification with real weak values
Jing-Hui Huang, Kyle M. Jordan, Adetunmise C. Dada +2
We introduce an ultra-sensitive interferometric protocol that combines weak value amplification (WVA) with traditional interferometry. This protocol WVA + interferometry uses weak…
