Quantum Blockchain Miners Provide Massive Energy Savings
Joseph Kearney, Carlos A Perez-Delgado
Blockchain-based cryptocurrencies have become an extremely important, highly-used, technology. A major criticism of cryptocurrencies, however, is their energy consumption. In May 2…
Overcoming efficiency constraints on blind quantum computation
Carlos A. Pérez-Delgado, Joseph F. Fitzsimons
Blind quantum computation allows a user to delegate a computation to an untrusted server while keeping the computation hidden. A number of recent works have sought to establish bou…
Limitations on information theoretically secure quantum homomorphic encryption
Li Yu, Carlos A. Perez-Delgado, Joseph F. Fitzsimons
Homomorphic encryption is a form of encryption which allows computation to be carried out on the encrypted data without the need for decryption. The success of quantum approaches t…
Fundamental Limits of Classical and Quantum Imaging
Carlos A. Pérez-Delgado, Mark E. Pearce, Pieter Kok
Quantum imaging promises increased imaging performance over classical protocols. However, there are a number of aspects of quantum imaging that are not well understood. In particul…
General optimality of the Heisenberg limit for quantum metrology
Marcin Zwierz, Carlos A. Perez-Delgado, Pieter Kok
Quantum metrology promises improved sensitivity in parameter estimation over classical procedures. However, there is an extensive debate over the question how the sensitivity scale…
