Minimum-cost quantum measurements for quantum information
Petros Wallden, Vedran Dunjko, Erika Andersson
Knowing about optimal quantum measurements is important for many applications in quantum information and quantum communication. However, deriving optimal quantum measurements is of…
Realization of Quantum Digital Signatures without the requirement of quantum memory
Robert J. Collins, Ross J. Donaldson, Vedran Dunjko +5
Digital signatures are widely used to provide security for electronic communications, for example in financial transactions and electronic mail. Currently used classical digital si…
Quantum Digital Signatures without quantum memory
Verdan Dunjko, Petros Wallden, Erika Andersson
Quantum Digital Signatures (QDS) allow for the exchange of messages from one sender to multiple recipients, with the guarantee that messages cannot be forged or tampered with. Addi…
Markovian evolution of strongly coupled harmonic oscillators
Chaitanya Joshi, Patrik Ohberg, James D. Cresser +1
We investigate how to model Markovian evolution of coupled harmonic oscillators, each of them interacting with a local environment. When the coupling between the oscillators is wea…
Universal quantum computation by the unitary control of ancilla qubits and using a fixed ancilla-register interaction
Timothy J. Proctor, Erika Andersson, Viv Kendon
We characterise a model of universal quantum computation where the register (computational) qubits are controlled by ancillary qubits, using only a single fixed interaction between…
Experimental demonstration of quantum digital signatures using phase-encoded coherent states of light
Patrick J. Clarke, Robert J. Collins, Vedran Dunjko +3
Digital signatures are frequently used in data transfer to prevent impersonation, repudiation and message tampering. Currently used classical digital signature schemes rely on publ…
