Fast Quantum Interconnects via Neutral Atom Ensembles
Sina Zeytinoglu, Wenchao Xu, Thomas Pohl
Distributing entanglement between distant qubits is a crucial element of scalable quantum computing. Here, we describe a scalable quantum interconnect that generates remote entangl…
Controlling Rydberg atom-polariton interactions: from exceptional points to fast readout
Tamara Šumarac, Emily H. Qiu, Shai Tsesses +8
Rydberg atoms represent a platform underpinning many recent developments in quantum computation, simulation, sensing, and metrology. They further facilitate optical nonlinearity at…
Dual-type dual-element atom arrays for quantum information processing
Zhanchuan Zhang, Jeth Arunseangroj, Wenchao Xu
Neutral-atom arrays are a leading platform for quantum technologies, offering a promising route toward large-scale, fault-tolerant quantum computing. We propose a novel quantum pro…
Bose-Einstein condensation by polarization gradient laser cooling
Wenchao Xu, Tamara Šumarac, Emily H. Qiu +7
Attempts to create quantum degenerate gases without evaporative cooling have been pursued since the early days of laser cooling, with the consensus that polarization gradient cooli…
Individual-atom control in array through phase modulation
Guoqing Wang, Wenchao Xu, Changhao Li +2
Performing parallel gate operations while retaining low crosstalk is an essential step in transforming neutral atom arrays into powerful quantum computers and simulators. Tightly f…
Fast Preparation and Detection of a Rydberg Qubit using Atomic Ensembles
Wenchao Xu, Aditya V. Venkatramani, Sergio H. Cantú +4
We demonstrate a new approach for fast preparation, manipulation, and collective readout of an atomic Rydberg-state qubit. By making use of Rydberg blockade inside a small atomic e…
Repulsive photons in a quantum nonlinear medium
Sergio H. Cantu, Aditya V. Venkatramani, Wenchao Xu +4
The ability to control strongly interacting light quanta (photons) is of central importance in quantum science and engineering. Recently it was shown that such strong interactions…
Correlated Spin-Flip Tunneling in a Fermi Lattice Gas
Wenchao Xu, William Morong, Hoi-Yun Hui +2
We report the realization of correlated, density-dependent tunneling for fermionic 40K atoms trapped in an optical lattice. By appropriately tuning the frequency difference between…
Bad-Metal Relaxation Dynamics in a Fermi Lattice Gas
Wenchao Xu, William McGehee, William Morong +1
We report the discovery of phenomena consistent with bad-metal relaxation dynamics in the metallic regime of an optical-lattice Hubbard model. The transport lifetime induced by int…
Velocity-selective EIT measurement of potassium Rydberg states
Wenchao Xu, Brian DeMarco
We demonstrate a velocity selection scheme that mitigates suppression of electromagnetically induced transparency (EIT) by Doppler shifts for low--high EIT probe--coupling waveleng…
