Quantum Optics with Atomic Ensembles and Single Atoms in Cavities
Current experiments in our group explore the quantum interface between matter and light, with the goal of achieving coherent control for implementing quantum information protocols and quantum networks. We outline recent progress in this direction, including localization to the ground state of motion for an atom trapped in an optical cavity, observation of strong coupling between single Cesium a...
متن کاملQuantum Computing using Linear Optics
uantum computers are expected to be able to solve mathematical problems that cannot be solved using conventional computers. Many of these problems are of practical importance, especially in the areas of cryptography and secure communications. APL is developing an optical approach to quantum computing in which the bits, or “qubits,” are represented by single photons. Our approach allows the use ...

متن کاملQuantum phonon optics: Coherent and squeezed atomic displacements.
We investigate coherent and squeezed quantum states of phonons. The latter allow the possibility of modulating the quantum fluctuations of atomic displacements below the zero-point quantum noise level of coherent states. The expectation values and quantum fluctuations of both the atomic displacement and the lattice amplitude operators are calculated in these states—in some cases analytically. W...
متن کاملTopological Quantum Optics in Two-Dimensional Atomic Arrays.
We demonstrate that two-dimensional atomic emitter arrays with subwavelength spacing constitute topologically protected quantum optical systems where the photon propagation is robust against large imperfections while losses associated with free space emission are strongly suppressed. Breaking time-reversal symmetry with a magnetic field results in gapped photonic bands with nontrivial Chern num...
