Quantum computer architecture with ions in tweezer arrays
Benjamin F. Schiffer, Christopher Monroe, Peter Zoller +1
We propose a quantum computer architecture based on ions confined in optical tweezer arrays, combining the long coherence times of trapped-ion qubits with the reconfigurability and…
Learning mixed quantum states in large-scale experiments
Matteo Votto, Marko Ljubotina, Cécilia Lancien +5
We present and test a protocol to learn the matrix-product operator (MPO) representation of an experimentally prepared quantum state. The protocol takes as an input classical shado…
Many-body entropies and entanglement from polynomially-many local measurements
Benoît Vermersch, Marko Ljubotina, J. Ignacio Cirac +3
Estimating global properties of many-body quantum systems such as entropy or bipartite entanglement is a notoriously difficult task, typically requiring a number of measurements or…
Quantum entanglement in spinor Bose-Einstein condensates
L. -M. Duan, J. I. Cirac, P. Zoller
We propose a scheme to generate and detect various kinds of quantum entanglement in a spin-1 Bose-Einstein condensate. It is shown that substantial many-particle entanglement can b…
Separability Criterion for all bipartite Gaussian States
G. Giedke, B. Kraus, M. Lewenstein +1
We provide a necessary and sufficient condition for separability of Gaussian states of bipartite systems of arbitrarily many modes. The condition provides an operational criterion…
Distillability Criterion for all Bipartite Gaussian States
G. Giedke, L. -M. Duan, J. I. Cirac +1
We prove that all inseparable Gaussian states of two modes can be distilled into maximally entangled pure states by local operations. Using this result we show that a bipartite Gau…
Physical implementation for entanglement purification of Gaussian continuous variable quantum states
Lu-Ming Duan, G. Giedke, J. I. Cirac +1
We give a detailed description of the entanglement purification protocol which generates maximally entangled states with high efficiencies from realistic Gaussian continuous variab…
Lower Bounds for Attainable Fidelity in Entanglement Purification
G. Giedke, H. Briegel, J. I. Cirac +1
We derive lower bounds for the attainable fidelity of standard entanglement purification protocols when local operations and measurements are subjected to errors. We introduce an e…
