Large conditional single-photon cross-phase modulation
Kristin M. Beck, Mahdi Hosseini, Yiheng Duan +1
Deterministic optical quantum logic requires a nonlinear quantum process that alters the phase of a quantum optical state by through interaction with only one photon. Here, we…
Partially Nondestructive Continuous Detection of Individual Traveling Optical Photons
Mahdi Hosseini, Kristin M. Beck, Yiheng Duan +2
We report the continuous and partially nondestructive measurement of optical photons. For a weak light pulse traveling through a slow-light optical medium (signal), the associated…
Observation of Aubry transition in finite atom chains via friction
Alexei Bylinskii, Dorian Gangloff, Ian Counts +1
The highly nonlinear many-body physics of a chain of mutually interacting atoms in contact with a periodic substrate gives rise to complex static and dynamical phenomena, such as s…
Fast Compact Laser Shutter Using a Direct Current Motor and 3D Printing
Grace H. Zhang, Boris Braverman, Akio Kawasaki +1
We present a mechanical laser shutter design that utilizes a DC electric motor to rotate a blade which blocks and unblocks a light beam. The blade and the main body of the shutter…
Entanglement with Negative Wigner Function of Three Thousand Atoms Heralded by One Photon
Robert McConnell, Hao Zhang, Jiazhong Hu +2
Quantum-mechanically correlated (entangled) states of many particles are of interest in quantum information, quantum computing and quantum metrology. Metrologically useful entangle…
Carving complex many-atom entangled states by single-photon detection
Wenlan Chen, Jiazhong Hu, Yiheng Duan +3
We propose a versatile and efficient method to generate a broad class of complex entangled states of many atoms via the detection of a single photon. For an atomic ensemble contain…
