Quantum Blockchains CEO Speaks at Seminar in Oak Ridge Lab’s Quantum Information Science Section

Dr. Mirek Sopek, CEO of Quantum Blockchains, was recently invited by the Quantum Information Science Section of the Computational Sciences and Engineering Division at ORNL to share insights into the company’s work on enhancing blockchain security and contributing to the field of quantum cryptography during a seminar.
Dr. Sopek began his presentation by reviewing Quantum Blockchains’ initial research on Abstract Quantum Blockchains and the later development of Quantum Secured Blockchain (QSB), which is grounded in three fundamental aspects of Quantum Cryptography: Quantum Key Distribution (QKD), Quantum Random Number Generation (QRNG), and Post-Quantum Cryptography (PQC).
He then discussed the company’s ongoing development of a novel consensus protocol that leverages a quantum communication method known as Time-Bin Conference Key Agreement (CKA). This work, which is currently pending patent approval, aims for experimental validation using techniques similar to those employed in quantum-optics research at ORNL.
In the latter part of the seminar, Dr. Sopek introduced the concept of post-Quantum Key Distribution (pQKD), a solution born out of necessity to facilitate the deployment of QSB networks under challenging conditions. He also outlined company main offering, the Quantum Cryptography Migration System (QCMS), which is designed as a three-phase process to transition from emulated QKD to a provably secure key distribution system, allowing for manageable cost increments.
Then, Dr. Sopek referenced a recent „Position Paper on Quantum Key Distribution” published by four European national security agencies, noting that the critiques outlined in the paper do not detract from the validity and potential of Quantum Blockchains’ products and services, such as pQKD and QCMS.
Concluding the seminar, Dr. Sopek highlighted an initiative by the Lodz University of Technology (TUL) — where he serves as the chairman of the university council — to establish the Quantum Cryptography Evaluation Laboratory (QCEL) in collaboration with „Cluster Q,” a consortium aimed at advancing quantum technology development in Poland. This effort underscores the collaborative spirit and commitment to innovation that drives both Quantum Blockchains and the broader quantum technology community.
