Spatially-entangled Photon-pairs Generation Using Partial Spatially Coherent Pump Beam
Hugo Defienne, Sylvain Gigan
We demonstrate experimental generation of spatially-entangled photon-pairs by spontaneous parametric down conversion (SPDC) using a partial spatially coherent pump beam. By varying…
High-dimensional quantum encoding via photon-subtracted squeezed states
Francesco Arzani, Alessandro Ferraro, Valentina Parigi
We introduce a high-dimensional quantum encoding based on coherent mode-dependent single-photon subtraction from multimode squeezed states. This encoding can be seen as a generaliz…
Demonstration of Einstein-Podolsky-Rosen Steering Using Hybrid Continuous- and Discrete-Variable Entanglement of Light
A. Cavaillès, H. Le Jeannic, J. Raskop +7
Einstein-Podolsky-Rosen steering is known to be a key resource for one-sided device-independent quantum information protocols. Here we demonstrate steering using hybrid entanglemen…
Spontaneous emission of a sodium Rydberg atom close to an optical nanofibre
E Stourm, Y Zhang, M Lepers +5
We report on numerical calculations of the spontaneous emission rate of a Rydberg-excited sodium atom in the vicinity of an optical nanofibre. In particular, we study how this rate…
Remote preparation of continuous-variable qubits using loss-tolerant hybrid entanglement of light
H. Le Jeannic, A. Cavaillès, J. Raskop +2
Transferring quantum information between distant nodes of a network is a key capability. This transfer can be realized via remote state preparation where two parties share entangle…
Quantum Kibble-Zurek mechanism and critical dynamics on a programmable Rydberg simulator
Alexander Keesling, Ahmed Omran, Harry Levine +12
Quantum phase transitions (QPTs) involve transformations between different states of matter that are driven by quantum fluctuations. These fluctuations play a dominant role in the…
