Optical and microwave control of germanium-vacancy center spins in diamond
Petr Siyushev, Mathias H. Metsch, Aroosa Ijaz +13
A solid-state system combining a stable spin degree of freedom with an efficient optical interface is highly desirable as an element for integrated quantum optical and quantum info…

Valentina M. Berezanskaya, Igor Ya. Doskoch, Margarita A. Man'ko
In connection with the 150-th Anniversary of P. N. Lebedev, we present historical aspects of his scientific and organizing activity and recall his famous experimental observations…
Observables, evolution equation,and stationary states equation in the joint probability representation of quantum mechanics
Ya. A. Korennoy, V. I. Man'ko
Symplectic and optical joint probability representations of quantum mechanics are considered, in which the functions describing the states are the probability distributions with al…
Heralded temporal shaping of single photons enabled by entanglement
Valentin Averchenko, Denis Sych, Gerd Leuchs
We propose a method to produce pure single photons with an arbitrary designed temporal shape in a heralded, lossless and scalable way. As the indispensable resource, the method use…

Demid V. Sychev, Alexander E. Ulanov, Anastasia A. Pushkina +3
Superpositions of macroscopically distinct quantum states, introduced in Schroedinger's famous Gedankenexperiment, are an epitome of quantum "strangeness" and a natural tool for de…

Efficient interfaces between photons and quantum emitters form the basis for quantum networks and enable nonlinear optical devices operating at the single-photon level. We demonstr…
