Multiplatform modular quantum computers since 2011
Our co-founder and CEO Prof. Dr. Enrique (Kike) Solano has a long track record in the quantum computing space. Since more than a decade, with his first pioneering publications having been published in 2011, he and his global collaborators have been developing the scientific foundation behind our key technology concepts – modular, multiplatform, co-designed quantum computers.
Recent publications and patent applications
Selected historic publications
This list is a selection of Kike Solano’s research articles containing both theory and experimental works in modular and codesign quantum simulation and quantum computation involving Embedding Quantum Simulators (EQS), Digital-Analog Quantum Simulation (DAQS), Digital-Analog Quantum Computing (DAQC), Digitized-Adiabatic Quantum Computing, as well as the first works on Modular Quantum Simulation and Modular Quantum Computing in their evolution along the past decade. It also show-cases our strong network of collaborators which reaches to several universities and many leading companies.

This is the pioneering paper where celebrated VQE algorithm was applied to quantum chemistry models in trapped ions. These ideas were taken by top experimental groups in trapped ions (IQOQI, Innsbruck, Austria) and superconducting circuits (Google, Santa Barbara, US), and implemented in the lab.
Digital-analog quantum simulation of interacting fermions via exchange of bosons in quantum field theories (DAQS): L. García-Álvarez, J. Casanova, A. Mezzacapo, I. L. Egusquiza, L. Lamata, G. Romero, and E. Solano, “Fermion-Fermion Scattering in Quantum Field Theory with superconducting circuits”, Phys. Rev. Lett. 114, 070502 (2015).

In this work, we were able to describe a modular architecture for quantum computation of scattering processes between fermions, like electrons, via exchange of a continuum of bosonic modes, like photons in open air. Our proposal shows that you may reach quantum advantage with rather few quantum elements (qubits, cavities, open transmission lines), while the proposal of John Preskill and others, published in Science 2011 requires millions of qubits.
Mapping unphysical operations on a physical architecture in ion traps (CDQS): X. Zhang, Y. Shen, J. Zhang, J. Casanova, L. Lamata, E. Solano, M.-H. Yung, J.-N. Zhang, and K. Kim, “Time Reversal and Charge Conjugation in an Embedding Quantum Simulator”, Nat. Commun. 6, 7917 (2015).

Key experiment proving our prediction on how modular co-design concepts work nicely in the lab, in this case trapped ions.
