Broadband uniform-efficiency OAM-mode detector
Suman Karan, Martin P. Van Exter, Anand K. Jha
The high-dimensional basis of orbital angular momentum (OAM) has several added and unique advantages for photonics quantum technologies compared to the polarization basis, which is…
A fiber coupled cavity QED source of identical single photons
H. J. Snijders, J. A. Frey, J. Norman +6
A high-fidelity source of identical single photons is essential for numerous quantum technologies such as quantum repeaters and optical quantum information processing. Hallmarks th…
Purification of a single photon nonlinearity
H. Snijders, J. A. Frey, J. Norman +6
We show that the lifetime-reduced fidelity of a semiconductor quantum dot-cavity single photon nonlinearity can be restored by polarization pre- and postselection. This is realized…
Tomography and state reconstruction with superconducting single-photon detectors
Jelmer J. Renema, Giulia Frucci, Michiel J. A. de Dood +3
We perform quantum state reconstruction of coherent and thermal states with a detector which has an enhanced multiphoton response. The detector is based on superconducting nanowire…
Schmidt modes generated in parametric downconversion
Filippo M. Miatto, Henrique Di Lorenzo Pires, Stephen M. Barnett +1
This paper presents the general Schmidt decomposition of two-photon fields generated in spontaneous parametric down-conversion (SPDC). It discusses in particular the separation of…
Complete experimental characterization of a superconducting multiphoton nanodetector
J. J. Renema, G. Frucci, Z. Zhou +6
We present a complete method to characterize multiphoton detectors with a small overall detection efficiency. We do this by separating the nonlinear action of the multiphoton detec…
CNOT and Bell-state analysis in the weak-coupling cavity QED regime
Cristian Bonato, Florian Haupt, Sumant S. R. Oemrawsingh +4
We propose an interface between the spin of a photon and the spin of an electron confined in a quantum dot embedded in a microcavity operating in the weak coupling regime. This int…
Does Excess Quantum Noise Exist in Spontaneous Processes?
A. Aiello, M. P. van Exter, G. Nienhuis +1
We investigate the role of excess quantum noise in type-II degenerate parametric down conversion in a cavity with non-orthogonal polarization eigenmodes. Since only two modes are i…
Plasmon-assisted Quantum Entanglement
E. Altewischer, M. P. van Exter, J. P. Woerdman
The state of a two-particle system is called entangled when its quantum mechanical wave function cannot be factorized in two single-particle wave functions. Entanglement leads to t…
