Fock state interferometry for quantum enhanced phase discrimination

Reihaneh Shahrokhshahi, Saikat Guha, Olivier Pfister

We study Fock state interferometry, consisting of a Mach-Zehnder Interferometer with two Fock state inputs and photon-number-resolved detection at the two outputs. We show that it…

State-independent quantum tomography of a single-photon state by photon-number-resolving measurements

Rajveer Nehra, Aye Win, Miller Eaton +6

The Wigner quasiprobability distribution of a narrowband single-photon state was reconstructed by quantum state tomography using photon-number-resolving measurements with transitio…

Simulating realistic non-Gaussian state preparation

N. Quesada, L. G. Helt, J. Izaac +4

We consider conditional photonic non-Gaussian state preparation using multimode Gaussian states and photon-number-resolving detectors in the presence of photon loss. While simulati…

Broadband quadrature-squeezed vacuum and nonclassical photon number correlations from a nanophotonic device

V. D. Vaidya, B. Morrison, L. G. Helt +13

We report demonstrations of both quadrature squeezed vacuum and photon number difference squeezing generated in an integrated nanophotonic device. Squeezed light is generated via s…

Ultra-low-noise room-temperature quantum memory for polarization qubits

Mehdi Namazi, Connor Kupchak, Bertus Jordaan +2

Here we show an ultra-low noise regime of operation in a simple quantum memory in warm Rb atomic vapor. By modelling the quantum dynamics of four-level room temperature atoms, we a…

Direct measurement of the Wigner function by photon-number-resolving detection

Niranjan Sridhar, Reihaneh Shahrokhshahi, Aaron J. Miller +5

Photon-number-revolving (PNR) detection allows the direct measurement of the Wigner quasiprobability distribution of an optical mode without the need for numerically processing an…

Large-scale multipartite entanglement in the quantum optical frequency comb of a depleted-pump optical parametric oscillator

Reihaneh Shahrokhshahi, Olivier Pfister

We show theoretically that multipartite entanglement is generated on a massive scale in the spectrum, or optical frequency comb, of a single optical parametric oscillator (OPO) emi…

Parallel generation of quadripartite cluster entanglement in the optical frequency comb

Matthew Pysher, Yoshichika Miwa, Reihaneh Shahrokhshahi +2

Scalability and coherence are two essential requirements for the experimental implementation of quantum information and quantum computing. Here, we report a breakthrough toward sca…

Dynamics of entanglement of bosonic modes on symmetric graphs

F. Ghahhari, V. Karimipour, R. Shahrokhshahi

We investigate the dynamics of an initially disentangled Gaussian state on a general finite symmetric graph. As concrete examples we obtain properties of this dynamics on mean fiel…
