Disentangling speech from surroundings with neural embeddings
Ahmed Omran, Neil Zeghidour, Zalán Borsos +3
We present a method to separate speech signals from noisy environments in the embedding space of a neural audio codec. We introduce a new training procedure that allows our model t…
Dispersive optical systems for scalable Raman driving of hyperfine qubits
Harry Levine, Dolev Bluvstein, Alexander Keesling +7
Hyperfine atomic states are among the most promising candidates for qubit encoding in quantum information processing. In atomic systems, hyperfine transitions are typically driven…
SoundStream: An End-to-End Neural Audio Codec
Neil Zeghidour, Alejandro Luebs, Ahmed Omran +2
We present SoundStream, a novel neural audio codec that can efficiently compress speech, music and general audio at bitrates normally targeted by speech-tailored codecs. SoundStrea…
Probing Topological Spin Liquids on a Programmable Quantum Simulator
Giulia Semeghini, Harry Levine, Alexander Keesling +13
Quantum spin liquids, exotic phases of matter with topological order, have been a major focus of explorations in physical science for the past several decades. Such phases feature…
Quantum Phases of Matter on a 256-Atom Programmable Quantum Simulator
Sepehr Ebadi, Tout T. Wang, Harry Levine +12
Motivated by far-reaching applications ranging from quantum simulations of complex processes in physics and chemistry to quantum information processing, a broad effort is currently…
Multiparticle interactions for ultracold atoms in optical tweezers: Cyclic ring-exchange terms
Annabelle Bohrdt, Ahmed Omran, Eugene Demler +2
Dominant multi-particle interactions can give rise to exotic physical phases with anyonic excitations and phase transitions without local order parameters. In spin systems with a g…
Parallel implementation of high-fidelity multi-qubit gates with neutral atoms
Harry Levine, Alexander Keesling, Giulia Semeghini +8
We report the implementation of universal two- and three-qubit entangling gates on neutral atom qubits encoded in long-lived hyperfine ground states. The gates are mediated by exci…
Generation and manipulation of Schrödinger cat states in Rydberg atom arrays
Ahmed Omran, Harry Levine, Alexander Keesling +16
Quantum entanglement involving coherent superpositions of macroscopically distinct states is among the most striking features of quantum theory, but its realization is challenging,…
Large-Scale Uniform Optical Focus Array Generation with a Phase Spatial Light Modulator
Donggyu Kim, Alexander Keesling, Ahmed Omran +5
We report a new method to generate uniform large-scale optical focus arrays (LOFAs). By identifying and removing undesired phase rotation in the iterative Fourier-transform algorit…
Quantum Kibble-Zurek mechanism and critical dynamics on a programmable Rydberg simulator
Alexander Keesling, Ahmed Omran, Harry Levine +12
Quantum phase transitions (QPTs) involve transformations between different states of matter that are driven by quantum fluctuations. These fluctuations play a dominant role in the…
High-fidelity control and entanglement of Rydberg atom qubits
Harry Levine, Alexander Keesling, Ahmed Omran +7
Individual neutral atoms excited to Rydberg states are a promising platform for quantum simulation and quantum information processing. However, experimental progress to date has be…
Probing many-body dynamics on a 51-atom quantum simulator
Hannes Bernien, Sylvain Schwartz, Alexander Keesling +9
Controllable, coherent many-body systems can provide insights into the fundamental properties of quantum matter, enable the realization of new quantum phases and could ultimately l…
Revealing Hidden Antiferromagnetic Correlations in Doped Hubbard Chains via String Correlators
Timon A. Hilker, Guillaume Salomon, Fabian Grusdt +5
Topological phases, like the celebrated Haldane phase in spin-1 chains, defy characterization through local order parameters. Instead, non-local string order parameters can be empl…
