Team Objectives and Work Description_

Qilimanjaro builds on its expertise in superconducting qubits for gate-based quantum computers to focus on timely and affordable quantum advantage, by designing next-generation analog quantum processors with high quality qubits, which do not require quantum error correction and can therefore be faster-to-market.

Simulators have advanced humanity in tremendous ways by predicting the world and thus showing us how to harness its processes to our advantage. The tiny world of atoms, molecules and light obeys very different laws, however, than the macroscopic world we see with our own eyes: in the tiny world, atoms can exist in opposite configurations at the same time (superposition), can teleport from one location to the next, or can be entangled with another atom miles away.

At the Qilimanjaro hardware team, we are building simulators, called coherent quantum annealers (CQA), harnessing this quantum world. These CQA processors consist of a network of interconnected artificial atoms, where the interactions are user defined, and where the delicate quantum information carried within the network is kept and retrieved when desired.

Each CQA processor and its network is designed to simulate and solve a specific problem. These problems can be of a variety of ranges: from biology where one can simulate how certain drugs affect our health system, through physics where one can model many body interactions all the way to financial optimization problems. At the Hardware team we engineer our CQA processors to best simulate the task at hand!

Pol Forn-Díaz

Chief Hardware Architect

Pol obtained his PhD from TU Delft in 2010 with a study of superconducting flux qubits and the limits of the force of interaction with a superconducting resonator. He was then postdoctoral researcher with the Kimble group at the California Institute of Technology, working on the interface of cold atoms and photonic waveguides. In a second postdoctoral stage, he was a fellow at the Institute for Quantum Computing at the University of Waterloo, working with Dr C. Wilson and A. Lupascu on superconducting qubits interacting with the propagation of microwave fields. He is a partner at Entanglement Partners SL. In 2017, he was appointed BSC researcher to lead experimental efforts to build a quantum processor using superconducting circuits.

Daniel Szombati

Senior Quantum Engineer

Daniel has obtained his PhD from the TU Delft on quantum transport in exotic low temperature semiconductor physics. He then dived into the world of superconducting qubits by taking on research position first at the University of Queensland in Brisbane and then at the École Normale Supérieure de Lyon, where he made his contribution to the field via significant scientific publications on first principle qubit physics. He is now leading the research efforts at Qilimanjaro towards a first coherent adiabatic quantum computing processor.

Ramiro Sagastizabal

Senior Quantum Engineer

Ramiro has a degree in Physics from the National University of Cordoba (Argentina), Master in Physics from the University of Aix-Marseille (France). During his PhD at TU Delft (The Netherlands) he specialized in design, fabrication and control of superconducting qubits, where this quarter he will read his thesis entitled “Experimental Quantum Simulations with Noisy Intermmediate-Scale Quantum Processors”.

David Eslava

Quantum Engineer

David is a second year PhD student at the UAB Barcelona and obtained a fellowship from AGAUR-Agency for Management of University and Research Grants, as an Industrial PhD working in the hardware team of Qilimanjaro Quantum Tech. His Phd thesis is entitled: “Microwave technology for quantum processors”.

David’s PhD is looking at novel ways to enhance the readout of qubits. David is working on using new filters to improve coherence times and optimizing elements of the readout chain to improve the signal to noise ratio. These improvements will allow more complex problems to be solved using a quantum processor.

Yifei Chen

Quantum Engineer

Yifei just started the second year as a PhD student at the UAB Barcelona and obtained a fellowship from AGAUR-Agency for Management of University and Research Grants, as an Industrial PhD working in the hardware team of Qilimanjaro Quantum Tech.

Yifei ́s PhD thesis is entitled “Digital and Analog Quantum Computers”. She is aiming to build a digital quantum computer based on quantum gates with trasmons. At the same time, Yifei is exploring novel couplers for quantum annealers to improve the coherence between qubits.

David Quinn

Quantum Engineer

David is a second year PhD student at the UAB Barcelona and obtained a fellowship from AGAUR-Agency for Management of University and Research Grants, as an Industrial PhD working in the hardware team of Qilimanjaro Quantum Tech.

David ́s PhD thesis is focused on the “Study of scalability in superconducting quantum annealers”. David’s PhD is looking at novel ways to enhance the scalability of flux qubits for use in quantum annealing systems. David is working on using new materials systems to improve coherence times and using flip chip technology to enhance the interconnectivity of these qubits. These improvements will allow more complex problems to be solved using a quantum annealer.
