Refrigeration with Indefinite Causal Orders on a Cloud Quantum Computer
David Felce, Vlatko Vedral, Felix Tennie
We demonstrate non-classical cooling on the IBMq cloud quantum computer. We implement a recently proposed refrigeration protocol which relies upon indefinite causal order for its q…
Indefinite Causal Orders from Superpositions in Time
David Felce, Nicetu Tibau Vidal, Vlatko Vedral +1
Treating the time of an event as a quantum variable, we derive a scheme in which superpositions in time are used to perform operations in an indefinite causal order. We use some as…
Quantum Refrigeration with Indefinite Causal Order
David Felce, Vlatko Vedral
We propose a thermodynamic refrigeration cycle which uses Indefinite Causal Orders to achieve non-classical cooling. The cycle cools a cold reservoir while consuming purity in a co…
A Photonic Topological Mode Bound to a Vortex
Adrian J Menssen, Jun Guan, David Felce +2
Topological photonics sheds light on some of the surprising phenomena seen in condensed matter physics that arise with the appearance of topological invariants. Optical waveguides…
