Phase noise measurement of external cavity diode lasers and implications for optomechanical sideband cooling of GHz mechanical modes
Tobias J. Kippenberg, Albert Schliesser, Michael Gorodetsky
Cavity opto-mechanical cooling via radiation pressure dynamical backaction enables ground state cooling of mechanical oscillators, provided the laser exhibits sufficiently low phas…
Unforgeable Noise-Tolerant Quantum Tokens
Fernando Pastawski, Norman Y. Yao, Liang Jiang +2
The realization of devices which harness the laws of quantum mechanics represents an exciting challenge at the interface of modern technology and fundamental science. An exemplary…
Quantum Magnetomechanics with Levitating Superconducting Microspheres
O. Romero-Isart, L. Clemente, C. Navau +2
We show that by magnetically trapping a superconducting microsphere close to a quantum circuit, it is experimentally feasible to perform ground-state cooling and to prepare quantum…
Bose-Einstein condensate as a quantum memory for a photonic polarization qubit
Stefan Riedl, Matthias Lettner, Christoph Vo +3
A scheme based on electromagnetically induced transparency is used to store light in a Bose-Einstein condensate. In this process, a photonic polarization qubit is stored in atomic…
Gapless Hamiltonians for the toric code using the PEPS formalism
Carlos Fernández-González, Norbert Schuch, Michael M. Wolf +2
We study Hamiltonians which have Kitaev's toric code as a ground state, and show how to construct a Hamiltonian which shares the ground space of the toric code, but which has gaple…
Majorization theory approach to the Gaussian channel minimum entropy conjecture
Raul Garcia-Patron, Carlos Navarrete-Benlloch, Seth Lloyd +2
A longstanding open problem in quantum information theory is to find the classical capacity of an optical communication link, modeled as a Gaussian bosonic channel. It has been con…
