Roads towards fault-tolerant universal quantum computation
Earl T. Campbell, Barbara M. Terhal, Christophe Vuillot
Current experiments are taking the first steps toward noise-resilient logical qubits. Crucially, a quantum computer must not merely store information, but also process it. A fault-…
Optimal Quantum Metrology of Distant Black Bodies
Mark E. Pearce, Earl T. Campbell, Pieter Kok
Measurements of an object's temperature are important in many disciplines, from astronomy to engineering, as are estimates of an object's spatial configuration. We present the quan…
Shorter gate sequences for quantum computing by mixing unitaries
Earl Campbell
Fault-tolerant quantum computers compose elements of a discrete gate set in order to approximate a target unitary. The problem of minimising the number of gates is known as gate-sy…
Quantum metrology of spatial deformation using arrays of classical and quantum light emitters
Jasminder S. Sidhu, Pieter Kok
We introduce spatial deformations to an array of light sources and study how the estimation precision of the interspacing distance, d, changes with the sources of light used. The q…
Universal growth scheme for entanglement-ready quantum dots
Joanna Skiba-Szymanska, R. Mark Stevenson, Christiana Varnava +12
Efficient sources of individual pairs of entangled photons are required for quantum networks to operate using fibre optic infrastructure. Entangled light can be generated by quantu…
Path-dependent initialization of a single quantum dot exciton spin in a nano-photonic waveguide
Rikki J. Coles, David M. Price, Ben Royall +4
We demonstrate a scheme for in-plane initialization and readout of a single exciton spin in an InGaAs quantum dot (QD) coupled to a GaAs nanobeam waveguide. The chiral coupling of…
