We present an integrated single-photon detection device custom designed for quantum key distribution (QKD) with time-bin encoded single photons. We implemented and demonstrated a prototype photon-to-digital converter (PDC) that integrates an 8 × 8 s

We present the experimental results of the first reference frame independent time bin quantum key distribution. Despite a lack of active phase stabilization of the interferometers, 0.078 asymptotic secret key bits per second were generated.

Theoretical modeling and experimental verification demonstrate that pair of identical polarization maintaining fibers (PMF), with a relative rotation angle of 90°, will preserve any linear polarization state entering the fiber pair.

Avalanche photodiodes (APDs) are well-suited for single-photon detection on quantum communication satellites as they are a mature technology with high detection efficiency without requiring cryogenic cooling. They are, however, prone to significantly

We investigate the impact of fiber birefringence and spontaneous Raman scattering on the properties of photon pairs that are generated by the spontaneous four-wave mixing process in birefringent fibers. Starting from the formulation of the theory of

Despite its widespread use in fiber optics, encoding quantum information in photonic time-bin states is usually considered impractical for free-space quantum communication as turbulence-induced spatial distortion impedes the analysis of time-bin stat

We study a novel protocol for reference frame independent (RFI) quantum key distribution (QKD) using six states for Alice and four states for Bob, while previous RFI protocols require a six state analyzer for Bob. Our protocol can generate a secure k

We designed and implemented a novel combination of a Sagnac-interferometer with a Mach–Zehnder interferometer for a source of polarization-entangled photons. The new versatile configuration does not require multi-wavelength polarization optics, yet

We propose to integrate the positron emission tomography (PET) and the single-photon emission computed tomography (SPECT) into one single isotope-based medical imaging technique [1]. This technique overcomes several imaging artifacts due to photon sc
