Implementation of controllable universal unital optical channels
A. Shaham, T. Karni, H. S. Eisenberg
We show that a configuration of four birefringent crystals and wave-plates can emulate almost any arbitrary unital channel for polarization qubits encoded in single photons, where…
The Effect of Decoherence on the Contextual and Nonlocal Properties of a Biphoton
A. Shaham, H. S. Eisenberg
Quantum contextuality is a nonintuitive property of quantum mechanics, that distinguishes it from any classical theory. A complementary quantum property is quantum nonlocality, whi…
Entanglement Dynamics in the Presence of Controlled Unital Noise
A. Shaham, A. Halevy, L. Dovrat +2
Quantum entanglement is notorious for being a very fragile resource. Significant efforts have been put into the study of entanglement degradation in the presence of a realistic noi…
Realizing a variable isotropic depolarizer
A. Shaham, H. S. Eisenberg
We demonstrate an isotropic depolarizing channel with a controllable degree of depolarization. The depolarizer is composed of four birefringent crystals and half-wave plates. Quant…
Measurements of the dependence of the photon-number distribution on the number of modes in parametric down-conversion
L. Dovrat, M. Bakstein, D. Istrati +2
Optical parametric down-conversion (PDC) is a central tool in quantum optics experiments. The number of collected down-converted modes greatly affects the quality of the produced p…
Quantum process tomography of single photon quantum channels with controllable decoherence
A. Shaham, H. S. Eisenberg
We characterized unital quantum channels of single photon polarization qubits. The channels are composed of two birefringent crystals and wave-plates, where their decoherence prope…
Realizing controllable noise in photonic quantum information channels
A. Shaham, H. S. Eisenberg
Controlling the depolarization of light is a long-standing open problem. In recent years, many demonstrations have used the polarization of single photons to encode quantum informa…
