The twisted convolution identity and ghost -SICs from finite quantum dilogarithms
Marcus Appleby, Steven T. Flammia, Gene S. Kopp
Radchenko and Wheeler (RW) recently proved a finite pentagon relation for real quadratic special values of the modular quantum dilogarithm and used it to establish the rank- twi…
Gauge freedom and efficient algorithms for Lindbladian learning
Steven T Flammia, Savar D Sinha, Yu Tong
We study the problem of learning a local Lindbladian in the presence of state-preparation-and-measurement (SPAM) noise. Although recent work has developed scalable learning algorit…
Fermionic Averaged Circuit Eigenvalue Sampling
Adrian Chapman, Steven T. Flammia
Fermionic averaged circuit eigenvalue sampling (FACES) is a protocol to simultaneously learn the averaged error rates of many fermionic linear optical (FLO) gates simultaneously an…
Ansatz-free Hamiltonian learning with Heisenberg-limited scaling
Hong-Ye Hu, Muzhou Ma, Weiyuan Gong +4
Learning the unknown interactions that govern a quantum system is crucial for quantum information processing, device benchmarking, and quantum sensing. The problem, known as Hamilt…
A Constructive Approach to Zauner's Conjecture via the Stark Conjectures
Marcus Appleby, Steven T Flammia, Gene S Kopp
We propose a construction of complex equiangular lines in , also known as SICPOVMs, conjectured by Zauner to exist for all d. The construction gives a putativel…
Chasing shadows with Gottesman-Kitaev-Preskill codes
Jonathan Conrad, Jens Eisert, Steven T. Flammia
We consider the task of performing shadow tomography of a logical subsystem defined via the Gottesman-Kitaev-Preskill (GKP) error correcting code. Our protocol does not require the…
