Low rank matrix completion and realization of graphs: results and problems Open
The Netflix problem (from machine learning) asks the following. Given a ratings matrix in which each entry $(i,j)$ represents the rating of movie $j$ by customer $i$, if customer $i$ has watched movie $j$, and is otherwise missing, we woul…

Learning noise via dynamical decoupling of entangled qubits Open
Understanding noise in entangled systems is a prerequisite for developing scalable quantum computers. Here, we propose and apply multiqubit dynamical decoupling sequences that characterize noise during two-qubit gates. This noise is qualit…

Measurements of quartic coupling and vector boson scattering in ATLAS Open
Measurements of multiboson production at the LHC probe the electroweak gauge structure of the Standard Model for contributions from anomalous couplings. \nVector boson scattering and triboson production provide the opportunity to directly …

Realizing topologically ordered states on a quantum processor Open
Synthesizing topological order Topologically ordered matter exhibits long-range quantum entanglement. However, measuring this entanglement in real materials is extremely tricky. Now, two groups take a different approach and turn to synthet…

Demonstrating a Continuous Set of Two-qubit Gates for Near-term Quantum Algorithms Open
Quantum algorithms offer a dramatic speedup for computational problems in material science and chemistry. However, any near-term realizations of these algorithms will need to be optimized to fit within the finite resources offered by exist…
