Román Orús Lacort (Barcelona, 1979) is a Spanish theoretical physicist known for his work in quantum information science and quantum tensor networks. He is Ikerbasque Research Professor at the Donostia International Physics Center (DIPC), as well as co-founder and Chief Scientific Officer of Multiverse Computing.[1][2][3][4]

Academic Career

[edit]

Román Orús studied physics at the University of Barcelona where he obtained his Ph.D. supervised by José Ignacio Latorre in 2006. Afterwards he worked as a research fellow at the University of Queensland (Brisbane, Australia) with Guifré Vidal, and at the Max Planck Institute of Quantum Optics (Garching, Germany) with Ignacio Cirac.

He became Junior Professor of Condensed Matter Physics at the Johannes Gutenberg-Universität (Mainz, Germany) in 2013, and Ikerbasque Research Professor at DIPC (San Sebastián, Spain) in 2018. He also held visiting professorships at CNRS (Toulouse, France) and DIPC and has lectured at the Institute for Pure and Applied Mathematics at UCLA.

His foundational research on tensor networks for complex quantum systems contributed to the field’s modern research and applications in machine learning.[5][6][7][3]

Scientific Work

[edit]

Orús' doctoral thesis was the first in Spain on quantum algorithms, connecting them with quantum phase transitions.[8] Orús also developed tensor networks to study high-dimensional quantum complex systems at the University of Queensland in 2006.[9]

In 2013 he wrote a review on tensor networks states[10] (with over 2,000 citations) as well as follow-up papers on the topic.[11][12] Orús also obtained results on quantum many-body entanglement, including the discovery of the geometric entanglement of topologically-ordered systems.[13][14]

In cybersecurity,  Orús also developed examples of possible quantum cyberattacks for symmetric-key cryptographic protocols such as AES and Blowfish that could make those ciphers vulnerable using few-qubit quantum processors.[2]

He also developed industrial applications of tensor networks for machine learning[15], using tensor networks to compress Large Language Models such as ChatGPT and LLaMA, reducing size while retaining most of the original accuracy to improve energy costs and efficiency.[3][1]

Awards

[edit]

Orús has received several awards for his scientific work, including an Honorable Mention in the Václav Votruba Prize (2008), a Marie Curie Incoming International Fellowship (2009) and the Early Career Prize of the European Physical Society (2014), which he won alongside Ian Chapman.[16] With Multiverse Computing, Orús work was recognized by winning DIGITALEUROPE's Future Unicorn Award (2024) and CB Insights' Top 100 Most Promising AI Startup Recognition (2023).[17][18]

Business Career

[edit]

In 2018, Orús wrote an article with S. Mugel and E. Lizaso on the practical applications of quantum computing in finance [19] that demonstrates the potential impact of quantum computing in the financial industry which eventually led to the creation of Multiverse Computing.[20][21][22]

In 2019, together with E. Lizaso, S. Mugel and A. Rubio, Orús co-founded Multiverse Computing focused on quantum and quantum-inspired software solutions. Multiverse incorporated as a company in 2019 in San Sebastián (Spain) with the support of DIPC, BIC-Gipuzkoa and local authorities.

Orus’ work and commentary on AI and quantum computing have been broadly featured in the media.[23][24][25][26][27][28][29][30][4][2][1]

Other Activities

[edit]

Orús is steering board member of the journal Quantum, editor of the journal Symmetry, a member of the Quantum for Quants commission of the Quantum World Association, partner at Entanglement Partners, member of the Scientific Committee of the Pedro Pasqual Benasque Center for Science (CCBPP), and former president of the Specialized Group on Quantum Information at the Spanish Royal Physics Society.[31][32] [33] Since 2012, he has also co-organized one of the leading conferences worldwide on strongly correlated systems at the CCBPP.
