Impact and mitigation of Hamiltonian characterization errors in digital-analog quantum computation
Mikel Garcia-de-Andoin, Alatz Ãlvarez-Ahedo, Adrián Franco-Rubio +1
Digital-analog is a universal quantum computing paradigm which employs the natural entangling Hamiltonian of the system and single-qubit gates as resources. Here, we study the stab…

Matrix product states as thin torus limits of conformal correlators
Adrián Franco-Rubio, J. Ignacio Cirac, Germán Sierra
We introduce one-parameter families of spin chain ansatz wavefunctions constructed from chiral conformal field theory correlators on a torus, with the modular parameter servin…

Symmetry defects and gauging for quantum states with matrix product unitary symmetries
Adrián Franco-Rubio, Arkadiusz Bochniak, J. Ignacio Cirac
In this work, we examine the consequences of the existence of a finite group of matrix product unitary (MPU) symmetries for matrix product states (MPS). We generalize the well-unde…
