VANCOUVER, BC, June 5, 2023 /PRNewswire/ - BTQ Technologies Corp. (the "Company" or "BTQ") (NEO: BTQ) (FSE: NG3) (OTCQX: BTQQF), a global quantum technology company focused on securing mission-critical networks, is proud to announce its co-authorship of the groundbreaking research paper titled "Proof-of-work Consensus by Quantum Sampling."

The research paper, co-authored by BTQ Technologies, introduces a novel approach called coarse-grained boson-sampling (CGBS) as a quantum Proof-of-Work (PoW) scheme for blockchain consensus. Since its inception in 2011, boson-sampling has emerged as a prime candidate for demonstrating quantum advantage due to its simplicity and near-term requirements in comparison to other quantum algorithms.

The research team proposes the utilization of CGBS as a PoW scheme for blockchain consensus. Users engage in boson-sampling using input states that are dependent on the current block information, and subsequently commit their samples to the network. The team also determines CGBS strategies that can be employed to validate samples and reward successful miners. By combining rewards for miners committing honest samples and penalties for miners committing dishonest samples, a Nash equilibrium is achieved that incentivizes honest nodes.

The paper presents a groundbreaking solution to the classical Proof-of-Work (PoW) problem. By introducing a quantum consensus mechanism, the paper addresses the limitations of classical systems that rely on brute force methods to solve the inverse hashing problem. Instead, the proposed approach utilizes NISQ (Noisy Intermediate-Scale Quantum) hardware to achieve Proof-of-Work mining. This scheme not only offers a more efficient alternative to classical Bitcoin mining but also ensures resistance to attacks by quantum computers, providing post-quantum security.

This groundbreaking scheme is applicable to both Fock state boson sampling and Gaussian boson sampling, delivering remarkable speedup and energy savings when compared to classical hardware computation. The findings also suggest that Boson Sampling could serve as the first commercial application for NISQ devices, which holds immense implications for the field of quantum computing. This technological advancement effectively bridges the gap between quantum computing and blockchain, opening up new possibilities and demonstrating the promising future of this emerging technology. The research paper marks a significant step forward in the field of quantum technology and blockchain consensus algorithms.

"We take great pride in our contribution to this pioneering research paper on Proof-of-Work consensus by quantum sampling. The transformative nature of this innovative approach holds the promise of revolutionizing blockchain consensus algorithms by harnessing the immense power of quantum technology. This remarkable research serves as a testament to our unwavering commitment to providing cutting-edge solutions in the era of post-quantum security." - Olivier Roussy Newton, CEO of BTQ
