Strong unitary designs in optimal depth and space
Teodor Parella-Dilmé, Júlia Barberà-Rodríguez, Salvatore F. E. Oliviero +1
Unitary designs provide finite-moment approximations to Haar-random unitaries, with wide-ranging applications across physics and quantum information, from scrambling and black-hole…
Swap Network Augmented Ansätze on Arbitrary Connectivity
Teodor Parella-Dilmé, Jakob S. Kottmann, Antonio AcÃn
Efficient parametrizations of quantum states are essential for trainable hybrid classical-quantum algorithms. A key challenge in their design consists in adapting to the available…
Certification of quantum properties with imperfect measurements
Leonardo Zambrano, Teodor Parella-Dilmé, Antonio AcÃn +1
The accurate characterization of quantum systems is essential for the advancement of quantum technologies. In particular, certifying convex functions of quantum states plays a cent…
Reducing Entanglement With Physically-Inspired Fermion-To-Qubit Mappings
Teodor Parella-Dilmé, Korbinian Kottmann, Leonardo Zambrano +3
In ab-initio electronic structure simulations, fermion-to-qubit mappings represent the initial encoding step of the fermionic problem into qubits. This work introduces a physically…
