Quantum certification and benchmarking
J. Eisert, D. Hangleiter, N. Walk +5
Concomitant with the rapid development of quantum technologies, challenging demands arise concerning the certification and characterization of devices. The promises of the field ca…
Bounds on Multipartite Entangled Orthogonal State Discrimination Using Local Operations and Classical Communication
M. Hayashi, D. Markham, M. Murao +2
We show that entanglement guarantees difficulty in the discrimination of orthogonal multipartite states locally. The number of pure states that can be discriminated by local operat…
Classicality of spin-coherent states via entanglement and distinguishability
D. Markham, V. Vedral
We investigate the classical nature of the spin coherent states. In addition to being minimum uncertainty states, as the size of the spin, S, increases, the classical nature is see…
Quantum state discrimination: a geometric approach
D. Markham, J. A. Miszczak, Z. Puchala +1
We analyse the problem of finding sets of quantum states that can be deterministically discriminated. From a geometric point of view this problem is equivalent to that of embedding…
Experimental demonstration of graph-state quantum secret sharing
B. A. Bell, D. Markham, D. A. Herrera-Martà +4
Distributed quantum communication and quantum computing offer many new opportunities for quantum information processing. Here networks based on highly nonlocal quantum resources wi…
Experimental demonstration of a graph state quantum error-correction code
B. A. Bell, D. A. Herrera-MartÃ, M. S. Tame +3
Scalable quantum computing and communication requires the protection of quantum information from the detrimental effects of decoherence and noise. Previous work tackling this probl…
