Application-specific quantum computing since 2011
Our co-founder and Chief Scientist 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.
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.
Quantum simulation of materials with interacting fermions and bosons (DAQS): A. Mezzacapo, J. Casanova, L. Lamata, and E. Solano, “Digital Quantum Simulation of the Holstein Model in Trapped Ions”, Phys. Rev. Lett. 109, 200501 (2012). Link: [1207.2664] Digital Quantum Simulation of the Holstein Model in Trapped Ions (arxiv.org)
In this work, we developed the pioneering Co-Design quantum simulation/computation of materials involving fermions coupled to bosons, where bosons are represented by bosons, as it should be for efficiency reasons. Along these lines, many important models in material design for quantum computers can reach quantum advantage with a few dozens of quantum elements, be qubits, qutrits, cavity modes, or open transmission lines.
Transforming an analog block into another one by single-qubit pulses (DAQS): J. S. Pedernales, R. Di Candia, D. Ballester, E. Solano, “Quantum Simulations of Relativistic Quantum Physics in Circuit QED”, New J. Phys. 15, 055008 (2013). Link: Quantum simulations of relativistic quantum physics in circuit QED – IOPscience
Here, we applied a known co-design method and found a mysterious coincidence in mathematical structure between light-matter interactions and relativistic Dirac equations, similar to the ones appearing in monolayer and bilayer graphene.
Embedding quantum simulators to measure entanglement (EQS): R. Di Candia, B. Mejia, H. Castillo, J. S. Pedernales, J. Casanova, and E. Solano, “Embedding Quantum Simulators for Quantum Computation of Entanglement”, Phys. Rev. Lett 111, 240502 (2013). Link: [1306.0510] Embedding Quantum Simulators for Quantum Computation of Entanglement (arxiv.org)
In this manuscript, we develop the full theory of embedding quantum simulators/computers to reproduce antilinear operations, which are unphysical but present in useful applications. In particular, it is present in the definition of measures of entanglement, so here we manage to prove that measuring entanglement in dynamical systems works better in quantum computers with Co-Design embedding concepts.
