Bouchard, Frédéric ; Koutný, Dominik ; Hufnagel, Felix ; Hradil, Zdenek ; Rehácek, Jaroslav ; Yong-Siah, Teo ; Ahn, Daekun ; Jeong, Hyunseok ; Sánchez Soto, Luis Lorenzo ; Leuchs, Gerd ; Karimi, Ebrahim | The Optical Society Of America | 2019-06-24The ability to completely characterize the state of a system is an essential element for the emerging quantum technologies. Here, we present a compressed-sensing-inspired method to ascertain any rank-deficient qudit state, which we experimentall[...]texto impreso
Müller, C. R. ; Peuntinger, P. ; Dirmeier, T. ; Khan, I. ; Vogl, U. ; Leuchs, G. ; Sánchez Soto, Luis Lorenzo ; Teo, Y. S. ; Hradil, Zdenek ; ?ehá?ek, J. | American Physical Society | 2016-08-11The accuracy in determining the quantum state of a system depends on the type of measurement performed. Homodyne and heterodyne detection are the two main schemes in continuous-variable quantum information. The former leads to a direct reconstru[...]texto impreso
Mogilevtsev, D. ; Teo, Y.S. ; ?ehá?ek, Jaroslav ; Hradil, Zdenek ; Tiedau, J. ; Kruse, R. ; Harder, Georg ; Silberhorn, C. ; Sánchez Soto, Luis Lorenzo | IOP publishing ltd | 2017-09-13The physical nature of any quantum source guarantees the existence of an effective Hilbert space of finite dimension, the physical sector, in which its state is completely characterized with arbitrarily high accuracy. The extraction of this sect[...]texto impreso
?ehá?ek, J. ; Stoklasa, Bohumil ; Koutný, Dominik ; Hradil, Zdenek ; Sánchez Soto, Luis Lorenzo | The American Physical Society | 2019-11-07We derive fundamental precision bounds for single-point axial localization. For Gaussian beams, this ultimate limit can be achieved with a single intensity scan, provided the camera is placed at one of two optimal transverse detection planes. He[...]texto impreso
?ehá?ek, Jaroslav ; Hradil, Zdenek ; Teo, Yong Siah ; Sánchez Soto, Luis Lorenzo ; Ng, Hui Khoon ; Chai, Jing Hao ; Englert, Berthold-Georg | American Physical Society | 2015-11Measuring incomplete sets of mutually unbiased bases constitutes a sensible approach to the tomography of high-dimensional quantum systems. The unbiased nature of these bases optimizes the uncertainty hypervolume. However, imposing unbiasedness [...]texto impreso
Aiello, Andrea ; Paúr, Martin ; Stoklasa, Bohumil ; Hradil, Zdenek ; ?ehá?ek, Jaroslav ; Sánchez Soto, Luis Lorenzo | The Optical Society (OSA) | 2020-09-15We report the first, to the best of our knowledge, observation of concentrating paraxial beams of light in a linear nondispersive medium. We have generated this intriguing class of light beams, recently predicted by one of us, in both one- and t[...]texto impreso
Donohue, J. M. ; Ansari, V. ; ?ehá?ek, Jaroslav ; Hradil, Zdenek ; Stoklasa, Bohumil ; Paúr, Martin ; Sánchez Soto, Luis Lorenzo ; Silberhorn, C. | American Physical Society | 2018-08-27By projecting onto complex optical mode profiles, it is possible to estimate arbitrarily small separations between objects with quantum-limited precision, free of uncertainty arising from overlapping intensity profiles. Here we extend these tech[...]texto impreso
Paúr, Martin ; Stoklasa, Bohumil ; Grover, Jai ; Krzoc, Andrej ; Sánchez Soto, Luis Lorenzo ; Hradil, Zdenek ; ?ehá?ek, Jaroslav | Optical Society of America | 2018-09-25It has been argued that, for a spatially invariant imaging system, the information one can gain about the separation of two incoherent point sources decays quadratically to zero with decreasing separation. The effect is termed Rayleigh's curse. [...]texto impreso
?ehá?ek, Jaroslav ; Hradil, Zdenek ; Stoklasa, Bohumil ; Motka, Libor ; Sánchez Soto, Luis Lorenzo | Society of Photo-Optical Instrumentation Engineers (SPIE) | 2015Wavefront sensing is an advanced technology that enables the precise determination of the phase of a light field, a critical information for many applications, such as noncontact metrology, adaptive optics, and vision correction. Here, we reinte[...]
