BTQ Technologies and Quandela have signed a Memorandum of Understanding to evaluate the use of photonic quantum computing for validating blockchain transactions using BTQ’s Quantum Sampling Proof-of-Work (QSPoW) protocol. QSPoW is designed as a quantum-secure and energy-efficient alternative to classical Proof-of-Work systems, leveraging boson sampling rather than traditional hash computation.
Under the MoU, Quandela will provide both simulated and experimental boson-sampling datasets from its Perceval cloud platform to support QSPoW testing on BTQ’s quantum testnet. The companies aim to assess whether photonic quantum data can meet performance requirements while reducing energy costs associated with ASIC-based mining.
If benchmarks are met, BTQ and Quandela plan to explore commercialization opportunities, including potential integration of Quandela’s new Belenos quantum processor into QSPoW-based blockchain systems. The partnership also intends to evaluate error mitigation techniques and security implications of using photonic systems in consensus mechanisms.
QSPoW represents a response to security concerns raised by the potential of future quantum computers to compromise classical cryptographic protocols. BTQ’s design emphasizes quantum resistance while reducing computational overhead, providing a potential path to securing decentralized systems in the post-quantum era.
