Experimental Scattershot Boson Sampling
Marco Bentivegna, Nicolò Spagnolo, Chiara Vitelli +10
Boson Sampling is a computational task strongly believed to be hard for classical computers, but efficiently solvable by orchestrated bosonic interference in a specialised quantum…
The Coulomb Branch of 3d Theories
Mathew Bullimore, Tudor Dimofte, Davide Gaiotto
We propose a construction of the quantum-corrected Coulomb branch of a general 3d gauge theory with supersymmetry, in terms of local coordinates associated with an…
Mutation, Witten Index, and Quiver Invariant
Heeyeon Kim, Seung-Joo Lee, Piljin Yi
We explore Seiberg-like dualities, or mutations, for quiver quantum mechanics in the context of wall-crossing. In contrast to higher dimensions, the 1d Seiberg-duality…
Strong Optimized Conservative Fermi-LAT Constraints on Dark Matter Models from the Inclusive Photon Spectrum
Andrea Massari, Eder Izaguirre, Rouven Essig +3
We set conservative, robust constraints on the annihilation and decay of dark matter into various Standard Model final states under various assumptions about the distribution of th…
Verifying the quantumness of a channel with an untrusted device
Matthew F. Pusey
Suppose one wants to certify that a quantum channel is not entanglement-breaking. I consider all four combinations of trusted and untrusted devices at the input and output of the c…
Detecting crystal symmetry fractionalization from the ground state: Application to spin liquids on the kagome lattice
Yang Qi, Liang Fu
In quantum spin liquid states, the fractionalized spinon excitations can carry fractional crystal symmetry quantum numbers, and this symmetry fractionalization distinguishes differ…
