Journal ArticleDOI
Wavevector multiplexed atomic quantum memory via spatially-resolved single-photon detection
Michał Parniak,Michał Dąbrowski,Mateusz Mazelanik,Adam Leszczyński,Michał Lipka,Wojciech Wasilewski +5 more
TL;DR: The proposed protocol utilizing the multimode memory along with the camera will facilitate generation of multi-photon states, which are a necessity in quantum-enhanced sensing technologies and as an input to photonic quantum circuits.
Journal ArticleDOI
Beating the Rayleigh Limit Using Two-Photon Interference
Michał Parniak,Sebastian Borówka,Kajetan Boroszko,Wojciech Wasilewski,Konrad Banaszek,Rafał Demkowicz-Dobrzański +5 more
TL;DR: In this article, Hong-Ou-Mandel interference followed by spatially resolved detection of photons provides precise information on both the separation and the centroid for a pair of point emitters, avoiding tradeoffs inherent to single-photon measurements.
Journal ArticleDOI
Wavevector multiplexed quantum memory via spatially-resolved single-photon detection
Michał Parniak,Michał Dąbrowski,Mateusz Mazelanik,Adam Leszczyński,Michał Lipka,Wojciech Wasilewski +5 more
TL;DR: In this paper, a wavevector multiplexed quantum memory based on a cold atomic ensemble was demonstrated using a single-photon resolving camera, where the second-order correlation between Raman scattered photons was confirmed by an average value of the secondorder correlation function.
Journal ArticleDOI
Entanglement between Distant Macroscopic Mechanical and Spin Systems
Rodrigo A. Thomas,Michał Parniak,Christoffer Østfeldt,Christoffer B. Møller,Christoffer B. Møller,Christian Bærentsen,Yeghishe Tsaturyan,Yeghishe Tsaturyan,Albert Schliesser,Jürgen Appel,Emil Zeuthen,Eugene S. Polzik +11 more
TL;DR: In this article, the authors demonstrate the generation of an entangled state between the motion of a macroscopic mechanical oscillator and a collective atomic spin oscillator, as witnessed by an Einstein-Podolsky-Rosen variance below the separability limit.
Journal ArticleDOI
Resolution limits of spatial mode demultiplexing with noisy detection
TL;DR: In this paper, the problem of estimating the spatial separation between two mutually incoherent point light sources using the super-resolution imaging technique based on spatial mode demultiplexing (SME) was considered.
