Hyper-entangled photons
We experimentally demonstrate the first quantum system entangled in every degree of freedom (hyper-entangled). Using pairs of photons produced in spontaneous parametric downconversion, we verify entanglement by observing a Bell-type inequality violation in each degree of freedom: polarization, spatial mode and time-energy. We also produce and characterize maximally hyperentangled states and nov...
متن کاملManipulating Frequency Entangled Photons
A parametric down conversion source pumped by a monochromatic laser will produce frequency entangled photon pairs. We demonstrate this by an experiment in which five-dimensional frequency entanglement is manipulated at telecommunication wavelengths using commercially available components such as electro-optic phase modulators and narrowband frequency filters. A theoretical intuition for this ap...
متن کاملEntangled “Frankenstein” Photons
The H> and V> outputs of a Polarizing Beam Splitter can be combined to restore the original input superposition state, as long as no knowledge is obtained regarding the path taken through the PBS. Using this principle, it should be possible to create entangled photons from the identical H> and V> components of different polarization entangled photons. These “Frankenstein” photons will also be p...
متن کاملSingle and Entangled Photons
Quantum computing is a sought after technology that will greatly increase the speed and security of computations and communications. The understanding of quantum computing and information technology is dependent upon the understanding of quantum interactions. The difference between current computers and quantum computers lies in the fundamental units of information utilized. The qubit, which is...
متن کاملRoutes to Single and Entangled Photons
The advent of quantum information and computation science has placed stringent demands on optical sources, namely that produce single or entangled photons. Quantum cryptography, quantum radiometry, distributed quantum computing as well as adjacent technologies such as biomedical, and astronomical imaging and low power classical communication also rely on single photon technologies and their ent...
