Quantum Speed-Up at Zero Temperature via Coherent Catalysis
Gabriel A. Durkin
It is known that secondary non-stoquastic drivers may offer speed-ups or catalysis in some models of adiabatic quantum computation accompanying the more typical transverse field dr…
Goldilocks Probes for Noisy Interferometry via Quantum Annealing to Criticality
Gabriel A. Durkin
Quantum annealing is explored as a resource for quantum information beyond solution of classical combinatorial problems. Envisaged as a generator of robust interferometric probes,…
True Limits to Precision via Unique Quantum Probe
Sergey I. Knysh, Edward H. Chen, Gabriel A. Durkin
Quantum instruments derived from composite systems allow greater measurement precision than their classical counterparts due to coherences maintained between N components; spins, a…
Practical Quantum Metrology
Jonathan C. F. Matthews, Xiao-Qi Zhou, Hugo Cable +5
Quantum metrology research promises approaches to build new sensors that achieve the ultimate level of precision measurement and perform fundamentally better than modern sensors. P…
Estimation of Phase and Diffusion: Combining Quantum Statistics and Classical Noise
Sergey I. Knysh, Gabriel A. Durkin
Coherent ensembles of qubits present an advantage in quantum phase estimation over separable mixtures, but coherence decay due to classical phase diffusion reduces overall prec…
Scaling laws for precision in quantum interferometry and bifurcation landscape of optimal state
Sergey Knysh, Vadim N. Smelyanskiy, Gabriel A. Durkin
Phase precision in optimal 2-channel quantum interferometry is studied in the limit of large photon number , for losses occurring in either one or both channels. For losses…
