Acoustic frequency atomic spin oscillator in the quantum regime
Jun Jia, Valeriy Novikov, Tulio Brito Brasil +3
We experimentally demonstrate quantum behavior of a macroscopic atomic spin oscillator in the acoustic frequency range. Quantum back-action of the spin measurement, ponderomotive s…
Two-colour high-purity Einstein-Podolsky-Rosen photonic state
Tulio Brito Brasil, Valeriy Novikov, Hugo Kerdoncuff +2
Entanglement is the backbone of quantum information science and its applications. Entangled states of light are necessary for distributed quantum protocols, quantum sensing and qua…
Cavity-enhanced sum-frequency generation of blue light with near-unity conversion efficiency
Hugo Kerdoncuff, Jesper B. Christensen, Túlio B. Brasil +4
We report on double-resonant highly efficient sum-frequency generation in the blue range. The system consists of a 10-mm-long periodically poled KTP crystal placed in a double-reso…
Entangled resource for interfacing single- and dual-rail optical qubits
David Drahi, Demid V. Sychev, Khurram K. Pirov +4
Today's most widely used method of encoding quantum information in optical qubits is the dual-rail basis, often carried out through the polarisation of a single photon. On the othe…
Entanglement of macroscopically distinct states of light
Demid V. Sychev, Valeriy A. Novikov, Khurram K. Pirov +2
Schrödinger's famous Gedankenexperiment has inspired multiple generations of physicists to think about apparent paradoxes that arise when the logic of quantum physics is applied to…
