Alternating Projections Methods for Discrete-time Stabilization of Quantum States
Francesco Ticozzi, Luca Zuccato, Peter D. Johnson +1
We study sequences (both cyclic and randomized) of idempotent completely-positive trace-preserving quantum maps, and show how they asymptotically converge to the intersection of th…
Exact solution of corner-modified banded block-Toeplitz eigensystems
Emilio Cobanera, Abhijeet Alase, Gerardo Ortiz +1
Motivated by the challenge of seeking a rigorous foundation for the bulk-boundary correspondence for free fermions, we introduce an algorithm for determining exactly the spectrum a…
Multiqubit Spectroscopy of Gaussian Quantum Noise
Gerardo A. Paz-Silva, Leigh M. Norris, Lorenza Viola
We introduce multi-pulse quantum noise spectroscopy protocols for spectral estimation of the noise affecting multiple qubits coupled to Gaussian dephasing environments including bo…
Dynamical decoupling sequences for multi-qubit dephasing suppression and long-time quantum memory
Gerardo A. Paz-Silva, Seung-Woo Lee, Todd J. Green +1
We consider a class of multi-qubit dephasing models that combine classical noise sources and linear coupling to a bosonic environment, and are controlled by arbitrary sequences of…
Exact Solution of Quadratic Fermionic Hamiltonians for Arbitrary Boundary Conditions
Abhijeet Alase, Emilio Cobanera, Gerardo Ortiz +1
We present a procedure for exactly diagonalizing finite-range quadratic fermionic Hamiltonians with arbitrary boundary conditions in one of D dimensions, and periodic in the remain…
