Single-Photon Quantum Contextuality on a Chip
In classical physics, properties of objects exist independently of the context, i.e., whether and how measurements are performed. Quantum physics showed this assumption to be wrong, and that Nature is indeed "contextual". Contextuality has been observed in the simplest physical systems, such as single particles, and plays fundamental roles in quantum computation advantage. Here, we demonstrate ...
متن کاملSingle photon quantum cryptography.
We report the full implementation of a quantum cryptography protocol using a stream of single photon pulses generated by a stable and efficient source operating at room temperature. The single photon pulses are emitted on demand by a single nitrogen-vacancy color center in a diamond nanocrystal. The quantum bit error rate is less that 4.6% and the secure bit rate is 7700 bits/s. The overall per...

متن کاملOn-chip time resolved detection of quantum dot emission using integrated superconducting single photon detectors
We report the routing of quantum light emitted by self-assembled InGaAs quantum dots (QDs) into the optical modes of a GaAs ridge waveguide and its efficient detection on-chip via evanescent coupling to NbN superconducting nanowire single photon detectors (SSPDs). The waveguide coupled SSPDs primarily detect QD luminescence, with scattered photons from the excitation laser onto the proximal det...
متن کاملOn-chip single photon transfer with site-controlled quantum dots coupled to photonic crystal waveguides
The challenging goal of realizing on-chip quantum circuits in which spins are interfaced with photons that are then routed, processed and detected has triggered significant research efforts over the past decades [1]. InGaAs/GaAs quantum dots (QDs) integrated in photonic crystal (PhC) circuits are one of the most advanced technologies in this direction [2]. Most of the work has focused on Strans...
