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 serving…
Impact and mitigation of Hamiltonian characterization errors in digital-analog quantum computation
Mikel Garcia-de-Andoin, Alatz Álvarez-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…
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…
Gaussian matrix product states cannot efficiently describe critical systems
Adrián Franco-Rubio, J. Ignacio Cirac
Gaussian fermionic matrix product states (GfMPS) form a class of ansatz quantum states for 1d systems of noninteracting fermions. We show, for a simple critical model of free hoppi…
Entanglement renormalization for quantum fields with boundaries and defects
Adrián Franco-Rubio
The continuous Multiscale Entanglement Renormalization Ansatz (cMERA) [Haegeman et al., Phys. Rev. Lett. 110, 100402 (2013)] gives a variational wavefunctional for ground states of…
Emergent universality in critical quantum spin chains: entanglement Virasoro algebra
Qi Hu, Adrian Franco-Rubio, Guifre Vidal
Entanglement entropy and entanglement spectrum have been widely used to characterize quantum entanglement in extended many-body systems. Given a pure state of the system and a divi…
Entanglement renormalization for gauge invariant quantum fields
Adrian Franco-Rubio, Guifre Vidal
The continuous multiscale entaglement renormalization ansatz (cMERA) [Haegeman et al., Phys. Rev. Lett., 110, 100402 (2013)] is a variational wavefunctional for ground states of qu…
Continuous tensor network renormalization for quantum fields
Qi Hu, Adrian Franco-Rubio, Guifre Vidal
On the lattice, a renormalization group (RG) flow for two-dimensional partition functions expressed as a tensor network can be obtained using the tensor network renormalization (TN…
Entanglement and correlations in the continuous multi-scale entanglement renormalization ansatz
Adrián Franco-Rubio, Guifre Vidal
We investigate the entanglement structure of the continuous multi-scale entanglement renormalization ansatz (cMERA) [Haegeman et al., Phys. Rev. Lett., 110, 100402 (2013)] for grou…
